Magnet therapy uses the influence of magnetic flux on biological tissue. Electric current is induced in the tissue due to voltage change which causes a polarization of the cell membrane. One of fundamental phenomenon of electric current in biological tissue is a transfer of neural excitation or muscle contraction. The intensity of the effect is dependent on the magnetic flux density, repetition rate of the pulses, pulse time duration or envelope of the stimulation signal.
Water and biological molecules are diamagnetic substances. The magnetic field is not affected by diamagnetic substances. Therefore no loss of intensity or magnetic flux density occurs when passing through the biological structure or tissue.
Magnet therapy originally used permanent magnets with a stationary magnetic field. Natural magnets were applied especially to acupuncture points, or to the location of pain. Thereafter natural magnets were replaced by synthetic magnets and electromagnets of stationary magnetic field of higher induction than permanent magnets. In the last few decades, therapeutic methods have used mainly a pulsed magnetic field.
Existing methods of magnetic therapy generally tend to be limited to the key parameters of magnetic flux density and repetition rate. High values of magnetic flux density are reached at low repetition rate or vice versa. These combinations limit the effectiveness of muscle therapy at higher repetition rates over 50 Hz. Therefore the stimulation of deep structures or stimulation by high repetition rates or the combination of both is limited. Existing designs do not provide any device and/or method for stimulating biological structure at repetition rate over 50 Hz and magnetic flux density sufficient to cause at least partial muscle contraction repetitively. Additionally existing methods do not disclose time duration of the therapy.
Existing methods are also not able to provide stimulation of biological structures by pulsed magnetic field at repetition rates which exceed the frequency resolution of the biological structure. Some systems also require making physical contact with the patient since the magnetic field is weak or the stimulation signal cannot be transferred without the electrical contact. Generally, these known methods are limited to repetition rates over 50 Hz in order to provide biological structure stimulation. Furthermore, repetition rates exceeding 100 Hz are not utilized. The therapeutic methods at higher repletion rates over 100 Hz are provided only by electrotherapeutic methods.
Presently, muscle contraction leading to strengthening, training, myorelaxation or analgesic effect at higher repetition rates over 50 Hz and at sufficient intensity stimulus may be achieved only by direct current therapy. However, direct current methods require contact with the patient and even may be invasive. These methods can result in skin irritation, painful application especially for the stimulus of higher intensity, discomfort during the treatment, lack of deep tissue stimulation by non-invasive methods, and a lack of patient compliance with a prescribed therapy due to these factors.
The present invention generally relates to methods using the influence of magnetic and induced electric field on biological structure. The magnetic field is time-varying and high powered therefore the method is based on a value of magnetic flux density sufficient to induce at least partial muscle contraction.
In a first aspect, a method provides stimulation of biological structure using magnetic field at repetition rates exceeding 50 Hz for purpose of at least a partial muscle contraction.
In another aspect, the stimulation utilizes non-invasive and/or contactless transfer of the stimulation signal from an applicator to biological structure to evoke the action potential of the biological structure to induce at least partial muscle contraction. The applicator may include a source of magnetic field e.g. a coil.
The method may provide a non-invasive transfer of a stimulation signal from an applicator to biological structure to evoke the action potential of biological structure.
The method may use a peak to peak magnetic flux density on a coil surface at least 0.2 T, 0.4 T, 1.5 T, 2 T, or at least 3 T. The repetition rate may exceed 50 Hz, 80 Hz, 90 Hz, 100 Hz or 120 Hz, and up to 150 Hz, with preferable repetition rate up to 700 Hz. with initial or successive treatments lasting several seconds or longer, for example, for at least 5, 10, 30, 60, 120 or 240 seconds, or longer. The pulse width is in the range of tens to hundreds of microseconds.
In another aspect of the invention, a neuromuscular plate is stimulated causing an at least partial contraction of the muscle. The muscle is contracted at higher repetition rates and the contraction is stronger and more efficient for improving the muscle strength. The method is especially useful for deep muscles, major muscles, and for treatment of patients with high value of BMI. Deep muscle is the muscle underneath the superficial muscle. Muscle tissues may be selectively stimulated and the magnetic flux density of the stimulation may be adjusted based on patient characteristics or input. Treatment time can be shortened to a minimum due to selective stimulation of targeted muscles. Additionally, the treatment may be non-invasive or even contactless due to the high value of magnetic flux density. The patient may be treated without removing clothing, thereby reducing patient discomfort.
In further aspect, a neuromuscular plate and/or the nerve innervating the neuromuscular plate is stimulated and at least partial muscle contraction is provided. The muscle may be contracted at higher repetition rates and the contraction is stronger. Therefore the stimulation is more efficient for reducing the number and/or volume of adipocytes and enhancing the visual appearance of the treated body area via targeted muscle contraction. Additionally, strong muscle contractions at higher repetition rates cause mechanical movement of all the layers in proximity of the contracted muscle. This method therefore causes remodeling and/or neogenesis of the collagen and elastin fibres.
The present methods may be used for enhancing visual appearance of body areas including adipose tissue reduction, muscle toning, muscle shaping, body contouring, body shaping, skin tightening, cellulite treatment, circumferential reduction, breast enhancement and/or lip enhancement.
The target biological structure may be a joint. Due to the pulsed magnetic field, the dynamic fluid properties of synovial fluid are improved and muscle contraction is achieved, contributing to positioning of the joint by short movements of the joint compartments.
In another aspect of the invention the repetition rate may exceed the frequency resolution of the structure. The magnetic flux density of the stimulation signal may increase over time. Therefore the envelope of resulting stimulation signal is increasing and it is perceived by the stimulated biological structure as a continuous stimulation signal instead of plurality of discrete stimuli. The envelope may be preferably triangular and other shapes may be used as well. This method is effective for stimulation of denervated muscle.
The envelope may be generated by time-varying magnetic flux density and/or repetition rate and/or impulse duration.
In a further aspect of the invention, the method stimulates the biological structure via a magnetic stimulation signal of at least 100 Hz, where the stimulation is intended for at least partial muscle contraction. The pulsed magnetic field induces the electric current which may provide myorelaxation. The stimulation signal repetition rate may be at least 120 Hz or at least 140 Hz.
Alternatively the treatment may combine a plurality of different treatment methods using different approaches. Such a combination may be magnetic treatment in combination with optical treatment, electromagnetic treatment such as radiofrequency treatment and/or treatment using mechanical interactions such as ultrasound wave, acoustic wave, shock wave treatment (SWT) which may be unfocused or focused.
The present invention relates to device and methods for treating a patient by a magnetic and/or electromagnetic field.

Electric current is induced in the stimulated biological structure during pulsed magnet therapy. A distribution of a magnetic field is uniform in the biological structure. Particles (e.g. atoms, ions, molecules etc.) in the biological structures are affected by the magnetic field and permeability of a cell membrane also increases.
Due to increased permeability of the cell membrane, an action potential may occur and a partial or full muscle contraction is induced. Convenient repetition rates may cause pain relief and/or myorelaxation, different repetition rate may cause stimulation of denervated muscle, and further different repetition rates may improve movability of a joint.
Advantages of the present magnet therapy include: affecting the deep structures which are problematically stimulated by superficial stimulation; non-invasive or non-contact application of magnetic flux, it may be applied even with clothes; absolute non-invasiveness of the stimulation and elimination of skin irritation in the place of magnetic field application; high rate of acceptability of the stimulation by patients; elimination of stimulation side effects; elimination necessity of applicator made of biocompatible materials; providing a clean and sterile applicator on the highest level; possibility of local or area treatment.
It is to be understood that the method is not limited to the particular applications and that the method may be practiced or carried out in various ways.
The present methods may use magnetic stimulation of magnetic flux density at least sufficient to cause active response of a biological structure at the repetition rates at least 50 Hz. The broad spectrum of application of biological structure stimulation by magnetic field is achieved due to high repetition rates and/or high value of magnetic flux density. Methods are intended especially for at least partial muscle contraction.
The magnetic stimulation of the biological structure has various applications for enhancing visual appearance of the contour body area. High density magnetic field reaches such values which may be used for: adipose tissue reduction, wherein the adipose tissue reduction is achieved by reduction of number and/or volume of adipose cells; muscle toning, wherein the muscle appearance enhancement is achieved by adipose tissue reduction with no muscle bulking; muscle shaping, wherein the muscle appearance enhancement is achieved by adipose tissue reduction and/or muscle bulking; body contouring, wherein the silhouette appearance enhancement is achieved by adipose tissue reduction with no muscle bulking; body shaping, wherein the silhouette appearance enhancement is achieved by adipose tissue reduction and/or muscle bulking; skin tightening, wherein the skin appearance enhancement is achieved by obtaining smoother and younger appearance, including wrinkles reduction; cellulite treatment, wherein the appearance enhancement is achieved by adipose tissue reduction, muscle contraction and/or elastic fibres neogenesis; circumferential reduction, wherein the reduction is achieved by adipose tissue reduction and/or the muscle bulking; breast enhancement, wherein the appearance enhancement effect is achieved by elevation or shape modification; lip enhancement, wherein the lip appearance enhancement is achieved by obtaining fuller and firmer appearance.
One application of time-varying magnetic field for enhancing the visual appearance of body area may be stimulation of a muscle by magnetic flux density for reducing the cellulite. The magnetic flux density is delivered through the skin to the neuromuscular plate and/or nerve innervating at least one muscle fibre. The electric current is induced in the target biological structure causing at least partial muscle contraction. The at least partial muscle contraction causes the movement of the skin and all the biological structures subtending epidermis. Additionally, the at least partial muscle contraction improves blood circulation by itself, or via the movement of the muscle in the vicinity including fibrous septae. Additionally, blood and/or lymph circulation is improved in the layers subtending epidermis since the muscle contraction moves the fibrous septae. Also local and/or adipose tissue metabolism is improved. The at least partial muscle contraction is more effective for adipose tissue metabolism as the value of magnetic flux density increases since the muscle contraction is stronger. The higher magnetic flux density effects the higher number of muscle fibres contraction and the more adipose tissue is reduced. Therefore the visual appearance of regions prone to cellulite is enhanced.
The method causes the circumferential reduction i.e. a reduction of the size of the treated body area. The method is mostly indicated for the regions with cellulite, especially for buttocks, abdomen, hips, thighs or arms. However, the indication is not limited to the mentioned regions and the method may be used for stimulation of any other body area.
The present method may provide a massage effect via the stimulation which is caused by the at least partial muscle contraction. Therefore the massage effect may be achieved by contactless methods instead of manual massage techniques or soft tissue techniques. The massage effect improves lymph circulation.
With the present method muscle contractions induced by the applied magnetic flux density help to tone the muscle providing a more attractive appearance. As the muscle structure is stimulated by time-varying magnetic field the entire limb may be moved due to the high power of the magnetic stimulation signal. Nevertheless, the method is not limited to the applications to the limbs and the method is able to be applied to stimulation of any muscle, e.g. gluteus maximus or any muscle/deep muscle to induce body contouring and/or body shaping effect and fat burn. Additionally, shortened and/or flabby muscles are stretched. The physical fitness of the patient is improved as well.
The present methods may also induce muscle contraction to reduce effect of skin laxity. Skin laxity may be caused by e.g. the aging process or increasing number and/or volume of adipose cells which pulls down the skin by gravity, rapid weight loss or skin stretching during the pregnancy. The muscles are stimulated by the induced electric current to contract. Repetitive contractions cause the muscles to obtain the tonus and flexibility. Therefore the skin appearance is enhanced by stimulating the flabby muscles. The effect of skin tightening is achieved. The method also stimulates the creation of the collagen and elastin fibres in the layers subtending the epidermis hence the skin obtains enhanced visual appearance. The method may be widely applied but not limited to application to the regions of neck, breasts, arms or abdomen. The method provides the smoother and younger appearance of the skin to the patient.
Similar methods of stimulation the muscle structure by time-varying magnetic field for inducing the at least partial muscle contraction may be used for treatment of wrinkles as well. Wrinkles are results of extrinsic and intrinsic factors. Nowadays, wrinkles are considered to be negative effect of natural aging process which decreases the production of collagen and elastin fibres and weakens the skin which becomes thinner. As the muscle stimulation by the magnetic flux density induces at least partial muscle contraction, the stimulation of collagen and elastin fibres neogenesis is improved. Additionally, the muscles subtending the stimulated region are toned and the skin gets a younger and enhanced visual appearance. Therefore, the effect of skin tightening is achieved.
The present methods may improve the neogenesis and remodelling of collagen fibres in the lips to reach a full, plump and firmer appearance. The magnetic flux density is applied to the lips by an applicator. Therefore the lips become fuller and firmer without any need of invasive method such as injection of the synthetic fillers, permanent makeup or the facial implants. The present method stimulates the remodelling and/or neogenesis of collagen fibres in a natural way. Additionally, the collagen is natural substance of the human body which provides the elasticity to the structure.
The collagen constitutes around 30% of proteins. Treatment by time-varying magnetic field may induce the neocollagenesis. The collagen may be treated by various repetition rates, e.g. in the range of 1 to 250 Hz, more preferably in the range of 10 to 100 Hz, or up to 700 Hz. However, the repetition rate of 25 Hz may be preferably used because the results achieved by stimulation of repetition rate of 25 Hz were the most significant. High value of magnetic flux density may improve the neocollagenesis more than low value of magnetic flux density. Hence the magnetic flux density may be at least 0.5 T, more preferably 1 T, most preferably at least 2 T, or up to 7 T.
The present methods may be used for enhancing the visual appearance of breasts. Cooper's ligament may be stimulated, improved and/or firmed by the at least partial muscle contraction. The muscle stimulation induces the elevation of the breast tissue. Additionally, the breast tissue is stimulated to be modified in a shape, wherein the shape includes the size and/or the contour of the breast tissue. Therefore the visual appearance is enhanced and breasts are more attractive for the patient. The present method is a non-invasive alternative for current aesthetic surgery method for the treatment of sagging breast tissue. The present method provides a patient a method of breast visual appearance enhancement without surgery. Therefore the method lacks post-surgery complications such as scars, postoperative pain or long recovery period. Various treatment protocols may be used.
The present invention provides new methods of aesthetic treatment of a patient focused on remodeling the buttocks of the patient.
In one application, the muscle stimulation may induce the same effect as muscle exercising of buttocks. During the stimulation of buttocks the magnetic field is targeted to stimulation of muscles shaping the buttocks, e.g. tensor fasciae latae muscle or at least one of gluteal muscles: maximus, medius or minimus. In one preferred application all three gluteal muscles may be stimulated. Further other muscles may be stimulated, e.g. abdominal muscles, spinal muscles and/or thoracic muscles. By the complex stimulation and muscle contraction in the target area the stimulated muscles are strengthened, toned, the cellulite may be reduced and dimples may be removed. Buttocks and even the patient's figure may be enhanced in visual shape appearance and become more attractive. Buttocks become wellshaped, round, firm, well-trained, toned, smoother, tight and lifted. The complex stimulation may reduce hips, an make perfect round and lifted buttocks, increasing the self-confidence of the patient.
In still another application the magnetic treatment may be used for improving sport performances, such as the sports where the movement technique may be important factor for the result, e.g. pole vaulting, ski jump or gymnastics. The magnetic treatment may be applied to motoric cortex of the patient. The magnetic treatment may improve the production of newly created neural interconnection during the learning the skill. Hence specific sport performance may be learned in shorter time period and/or less number of repetitions. Furthermore the magnetic treatment may improve the movement coordination and/or the jumping force.
Alternatively the magnetic treatment influencing sport performance may be used in combined treatment preferably for regeneration after sport performance and/or for recovering of the athletes after injuries by regenerating the muscles, improving local metabolism, preventing atrophy and/or by selective training of correct motion patterns.
Alternatively the magnetic treatment may be used for strengthening the muscle in natural way following the motion pattern, e.g. dumbbell exercise of biceps. In an exemplary application the repetition rate of the treatment may be constant, e.g. at least 5 Hz, more preferably at least 20 Hz, even more preferably at least 40 Hz, most preferably at least at least 80 Hz, and the amplitude of magnetic flux density may vary, e.g. the amplitude of magnetic flux density may rise for a defined time period and decrease for a defined time period. The magnetic flux density may be in the range of 0.1 to 2.5 T, more preferably at least 0.5 to 2 T, even more preferably at least 1 T, or up to 7 T. The strength of the at least partial muscle contraction may correspond with the value of magnetic flux density. This exemplary application may cause a motion corresponding with motion during dumbbell exercise of biceps.
The treatment is more efficient than standard workout in fitness since the machines strengthen only the isolated muscles. The results may be achieved in very short-time periods with minimal time of treatment. Without being limited, it is believed that the exercising of the gluteus medius may reduce the volume of the buttocks; exercising of the gluteus maximus may shape and/or lift the buttocks; exercising of the gluteus minimus may lift the buttocks.
The one approach is stimulating central neural system or peripheral neural structure and determining the feedback, e.g. muscle contraction.
In still another application of the invention, the time-varying magnetic field may be used for stimulation of neural structure to cause muscle stimulation. The muscle stimulation may occur during stimulation by envelopes of repetition frequencies below 100 Hz.
In the preferred application the magnet treatment may be combined with other treatment methods using different approaches, e.g. conventional non-invasive treatments. The combined treatment may be applied to the surroundings tissues around buttocks to reduce the cellulite around the buttocks and enhance the shape of the enhanced appearance of the buttocks. The surrounding tissues may be represented by e.g. abdomen, love handles, thighs or saddle bags.
The present methods may be provided by the magnetic stimulation device which contains no magnetic core, however, the magnetic core may also be used. The magnetic stimulation device may be cooled by a fluid, such as air. The total power consumption may be preferable, but is not limited to values below 1.3 kW. Convenient therapeutic apparatus is described in the U.S. patent application Ser. No. 14/789,156 or U.S. patent application Ser. No. 14/789,658, incorporated herein by reference.
A device for time variable magnetic field generation may include an energy source, an energy storage device, a switching circuit, a coil and possibly a core. The energy storage device accumulates tens of Joules of energy and the magnetic flux density induced by the coil is in the range of tenths of a Tesla to about one Tesla.
The coil may be made of insulated wires with a conductor diameter less than 3 mm even more preferably less than 0.5 mm and most preferably less than 0.05 mm. Smaller diameter and individual insulation of the wires significantly reduces self-heating of the coil and therefore increase efficiency of magnetic stimulation device. The coil may be flexibly attached in a casing of device. The casing may comprise a blower or blowers which ensure cooling of the coil.
Space between the insulated wires may be filled with a solid material so as to reduce the noise caused by vibrations. The coil is connected with an energy storage device which serves as a storage of energy.
The switch can be any kind of switch such as diode, MOSFET, JFET, IGBT, BJT, thyristor or a combination of them. The switch can be connected in parallel to the coil and the energy storage device, to eliminate reversal polarity of high voltage on the terminals of the energy source in the second half of the resonant effect. Therefore there is no need for additional protective circuits to protect the energy source from the negative voltage. Electric losses associated with such protective circuits are avoided. Energy use is reduced. The voltage drop in the energy storage device between first and second oscillation maximum during resonance is also reduced. Via the lower voltage drop, higher repetition rates of magnetic pulses and higher magnetic flux density may be achieved for treatment of the patient.
The coil of the magnetic stimulation device may be flexibly attached to casing of the device. The blower or blowers may be arranged to blow air on both sides of coil. Optionally, the coil may be a flat type coil.
PEDDY=π2·BP2·d2·f2/6·k·ρ·D, Eq. 1
where: PEDDY is power loss per unit mass (W·kg−1); Bp is the peak of magnetic field (T); f is frequency (Hz); d is the thickness of the sheet or diameter of the wire (m); k is constant equal to 1 for a thin sheet and 2 for a thin wire; ρ is the resistivity of material (Ω·m); D is the density of material (kg·m3).
The individual insulation of each wire reduces eddy currents. The individually insulated wires may be wound either one by one or in a bundle of individually insulated wires so as to form a coil, which will serve as a magnetic field generator. The coil provides an improvement in the efficiency of energy transfer in the LC resonant circuit and also reduces or eliminates unwanted thermal effects.
The coil may have a planar coil shape where the individually insulated wires may have cross-section wires with conductor diameter less than 3 mm even more preferably less than 0.5 mm and most preferably less than 0.05 mm. The wires are preferably made of materials with higher density and higher resistivity e.g. gold, platinum or copper. The diameters of the single wires should be minimal. On the other hand the total diameter should be maximal because of inverse proportion between the cross-section of all wires forming the coil and the electrical resistance. Therefore the ohmic part of the heat is then lower. Eq. 2 describes power loss of the coil:
PR=ρ·l/S·I2/m Eq. 2
where: PR is the power loss heat dissipation (W); ρ is the resistance (Ω·m); l is the length of wire (m); S is the surface area (m2); I is the current (A) and m is 1 kg of wire material.
Total power loss is (Eq.3):
PTOT=PEDDY+PR Eq. 3
where: PTOT is the total power losses (W·kg−1); PEDDY is the power dissipation of eddy currents (W·kg−1); PR is the power loss heat dissipation (W·kg−1).
Dynamic forces produced by current pulses passing through the wires of the coil cause vibrations and unwanted noise. The individual insulated wires of the coil may be impregnated under pressure so as to eliminate air bubbles between the individual insulated wires. The space between wires can be filled with suitable material which causes unification, preservation and electric insulation of the system. Suitable rigid impregnation materials like resin, and elastic materials like PTE can be also used. With the coil provided as a solid mass, the vibrations and resonance caused by movements of the individual insulated wires are suppressed. Therefore noise is reduced.
The coil may be attached to the case of the applicator, such as a hand held applicator of the magnetic stimulation device; built-in applicator in e.g. chair, bed; or stand-alone applicator e.g. on mechanical fixture. The attachment may be provided by an elastic material e.g., silicone, gum; or other flexible manner. Connection with the coil of the applicator's case can be ensured by several points. The several fastening points ensure the connection of the coil to the casing by flexible material so that the main part of the coil and the main part of the casing of applicator are spaced apart. The spacing should be at least 0.1 mm so that air can easily flow. The gap between the coil and the casing can be used either for spontaneous or controlled cooling. The coil may optionally be connected to the case of the applicator by only one fastening point. The fastening points eliminate vibrations of wires which could be transferred to housing of the applicator and therefore reduce noise of the magnetic stimulation device.
The magnetic stimulation device may be cooled by a fluid, e.g. by a liquid or a gas. In the preferred embodiment the magnetic stimulation device is cooled by air.
The fastening points 12 connect the coil to the case of the applicator in at least one point. The fastening points 12 maintain the coil and the main part of the case of the applicator spaced apart so that fluid (which may be air or any liquid) can flow between them. At least one blower 13 can be placed around the circumference of the coil, or perpendicular to the coil. The blower can be any known kind of device for directing the fluid e.g. outer air directed into the case of the applicator. This arrangement of the blower allows air to bypass the coil from upper and lower (patient's) sides. In still another embodiment the outer air can be cooled before directing into the case. The blower can have an inlet placed around the circumference of the coil for injecting air, to remove heat from the coil. A connecting tube (not shown) can ensure connection of the applicator with the energy source and/or control unit of magnetic stimulation device. The connecting tube may also contain a conduit of the fluid.
The arrows 15 indicate the air flow through the applicator. This arrangement of the blower allows the air to bypass the coil from upper and lower (patient's) side. Outlet may be preferably placed on upper side of the casing. By placing the blower around the circumference of the coil instead of on the top/below the coil, the blower 13 does not interfere with the magnetic flux peak and therefore its lifespan and reliability is increased.
In
During second half-period of LC resonance, the polarity on the energy storage device 20 is reversed in comparison with the energy source 23. In this second half-period, there is a conflict between energy source 23, where voltage on positive and negative terminals is typically thousands of Volts. The energy storage device 20 is also charged to the positive and negative voltage generally to thousands of Volts. As a result, there is in the circuit, consequently, twice the voltage of the energy source 23. Hence the energy source 23 and all parts connected in the circuit are designed for a high voltage load. Therefore, the protective resistors and/or protection circuitry 24 must be placed between energy source 23 and energy storage device 20. As a result a large amount of energy is transformed to undesired heat in the protective resistors and/or protection circuitry 24.
The switch 32 can be any kind of switch such as diode, MOSFET, JFET, IGBT, BJT, thyristor or their combination. Depending on the type of component the load of energy source 33 is reduced to a few Volts, e.g., 1-10 volts. Consequently, it is not necessary to protect the energy source 33 from a high voltage load, e.g., thousands of Volts. The use of protective resistors and/or protection circuits is reduced or eliminated. The present designs simplify the circuits used, increase efficiency of energy usage and provide higher safety.
The present invention provides a magnetic stimulation device and method of controlling the magnetic stimulation device using a plurality of magnetic field generating devices.
The magnetic stimulation device may include the at least one applicator, the at least one energy source and at least two magnetic field generating devices. However, in an alternative embodiment the magnetic stimulation device may include a plurality of applicators and/or plurality of energy sources. The plurality of applicators may be used for treatment of at least two cooperating muscle groups with different treatment effects. In an exemplary application e.g. the triceps brachii muscle may be treated to achieve myostimulation effects and the biceps brachii muscle may be treated to achieve myorelaxation effects.
The magnetic stimulation device may include a plurality of applicators. The applicator includes at least one magnetic field generating device which may be movable. The benefit of this embodiment is that the movement and/or positioning of the plurality of the applicators may be independent. Hence different parts of the patient's body may be treated simultaneously. Therefore the total treatment time is reduced and patient's downtimes are reduced as well. The movement of the at least one applicator may be automatic so that manual manipulation may not be needed. The movement of the at least one applicator may follow a predetermined trajectory or it may be random. In an alternative embodiment the movement of the plurality of applicators may be synchronized.
There is no necessity of constant movement of the applicator over a larger area. The applicator may remain in a stationary position relative to the patient for several seconds or longer, e.g. for at least 10, 30, 60, 120 or 240 seconds, or longer. The at least one applicator may be of such dimension which may allow to the treated biological structure to be within physiological conditions, e.g. the biological structure may not be overheated over critical temperature causing irreversible changes in the biological structure.
The static position of the at least one applicator may be provided by a positioning member. The positioning member may be e.g. an arm or an adjustable flexible belt. The positioning member may include a buckle for adjusting the length of the belt. The applicator may be placed within predefined locations of the belt. Alternatively the applicator may be shaped to be moveable along the positioning member, e.g. the shape of the applicator may be preferably concave, e.g. V-shaped or U-shaped. The positioning member may be inserted itself into the concavity of the applicator. The position of the applicator may be adjusted by limited movement along the positioning member because the positioning member may be used as guiding member. However, the applicator may not be fixed to a particular static position. The position of the applicator may be dynamically adjusted during the treatment following the patient's needs.

Using a plurality of magnetic field generating devices provides faster treatment. Large and/or different areas may be treated in shorter time. Using a plurality of applicators allows different areas and/or target biological structures to be stimulated at the same time. The movement of the at least one applicator may automatically follow a predetermined trajectory. Hence manual manipulation is not needed. Furthermore the shape of the generated magnetic field may be adjusted by an operator.
The treatment device and/or the applicator, preferably a hand-held applicator, may include a human machine interface including inputting and/or outputting interface, e.g. graphical user interface.

The treatment by the magnetic stimulation device may be in different operation modes. One operation mode may generate a plurality of impulses 61 at one time within the pulse 62 as illustrated in
The magnetic stimulation device may generate a plurality of the impulses 61 by the magnetic field generation devices L1, L2, . . . LN at one time within the pulse 62. This operation mode is illustrated in
The switching devices 707-709 may be switched separately, with the magnetic field generated by separate magnetic field generating devices.
In an alternative embodiment any switching device may be switched in combination with at least one other switching device.
The active magnetic field generating devices are the magnetic field generating device in the closed loop of the electric circuit. For example if the number of active magnetic field generating devices is 2 and the inductances of the magnetic field generating devices are the same, then the value of magnetic flux density for each magnetic field generating device is one-half of the magnetic flux density which would be reached by one active magnetic field generating device with the same parameters and conditions, e.g. inductance, resistance, frequency, voltage. The total equivalent inductance of the magnetic stimulation device may be changed by switching a plurality of switching devices into a closed electric circuit. Therefore the impulse duration may be adjusted by adjusting the inductance. The value of total equivalent inductance (Ltotal) may be determined by Equation 4.
1/Ltotal=1/L1+1/L2+ . . . +1/LN
The magnetic stimulation device may generate a plurality of impulses 61 generated by the magnetic field generation devices L1, L2, . . . LN at different times within the pulse 62. This operation mode is illustrated in
In the example of
The benefit of this exemplary embodiment is the time independency of the impulses generated by the separate magnetic field generating devices. However, the switching devices may be synchronized to generate the impulses at one fixed time within the pulse or both operation modes may be combined using this embodiment. Another benefit of this embodiment is the possibility of providing various treatments by a plurality of magnetic field generating devices. Various treatments may provide various effects for the patient, e.g. stimulation, such as myostimulation, pain alleviation or myorelaxation.
The impulses generated by the separate magnetic field generating devices are time independent. However, the switching devices may be synchronized to generate the impulses at one time within the pulse or both operation modes may be combined.

Inputting interface may include at least one input element, e.g. touch member such as touchscreen, keyboard or control member for adjusting the treatment or microphone for providing the information from operator. The operator may adjust e.g. a treatment protocol or may adjust treatment parameters following the patient's needs. A communication link between the human machine interface and control unit of the treatment device may be established.
The treatment parameters may be constant during the treatment. Alternatively the treatment may vary during the treatment. The treatment may be modulated. The treatment parameters may be adjusted by the operator following the patient's needs.
Repetition rate and/or magnetic flux density may vary during the treatment protocol. Further the magnetic stimulation signal may include several periods of stimulation signal of different repetition rates, therefore the modulation of the signal is in repetition rate domain. The stimulation signal may include several periods of stimulation signal of different magnetic flux densities, therefore the modulation of the signal is in magnetic flux density domain. In yet another approach the envelope of the stimulation signal may be modulated by combinations of repetition rate domain, magnetic flux density domain or impulse duration domain.
Various envelopes of the stimulation signal and waveform, e.g. pulse, sinusoidal, rectangular, square, triangular, saw-tooth, trapezoidal, exponential etc. for the purpose of muscle stimulation may also be used, and is not limited to recited shapes of stimulation signals.
The plurality of magnetic field generating devices may be used for treating at least two cooperating muscle groups.

In still another embodiment the at least partial muscle contraction may be determined visually.
The feedback information may be provided by determining an active response for stimulation, e.g. at least partial muscle contraction or change in biological structure characteristic. The at least partial muscle contraction may cause dynamic forces which may be determined by at least one sensor preferably placed beneath the patient, more preferably a plurality of sensors may be used as well. Alternatively at least one sensor may be within the applicator, e.g. for determining skin temperature or for determining the active response of the target biological structure. Following the feedback information the magnetic stimulation device may adjust the position and/or orientation of the magnetic field generating device with respect to the patient to improve the effectiveness of the treatment.

The video output may include a graphical processing, e.g. a game controlled via feedback information such as biofeedback application. The graphical user interface may provide instruction to the patient to improve the treatment, e.g. contraction of correct muscles. The output in human perceptible form may be adjusted by the operator following the patient's needs, e.g. a plurality difficulty levels may be set.
The applicator may be a loop-coil. The biological structure may be inserted to the area inside the loop-coil. The loop-coil applicator may provide a substantially homogenous magnetic flux density inside the coil.
The device can be used for treatment/successive treatments in continual, interrupted or various duty cycle regime. The duty cycle may be higher than 10%, which means interrupted regime with the ratio up to 1 active to 9 passive time units.

The pulse width is in the range of tens to hundreds of microseconds, e.g. 200, 400, 500 or 625 μs. The duty cycle of the stimulation may be at least 1:50, more preferably at least 1:40, even more preferably at least 1:20, most preferably at least 1:8 or up to 1:4.
The pulse width is in the range of tens to hundreds of μs, preferably in the range of 100 to 600 μs, most preferably in the range of 250 to 350 μs.
Repetition rate of the magnetic impulses may reach up to 700 Hz, more preferably up to 500 Hz, most preferably in the range of 1 to 300 Hz, e.g. 5, 30, 70, 120, 140 or 180 Hz.

The present methods may be used for muscle stimulation and exercising, e.g. for treatment of pelvic floor muscles, incontinence, etc. Incontinence is a disability of mainly older patients to restrain evacuations of urine or faeces. Incontinence is currently treated by exercising pelvic floor muscles or by utilizing vaginal or rectal probes using direct current therapy, or using urologic chairs using stimulation by pulsed magnetic field. However, urologic chairs achieve low magnetic flux density at high repetition rate. Efficacy of urological chairs is low because the values of stimulation parameters, repetition rate and magnetic flux density, are insufficient. Therefore the therapy is relatively time consuming and uncomfortable for the patient.
Another field of application may be treatment of erectile dysfunction. A synergic effect may also be myorelaxation.
The present methods may be used for various stimulation of any other muscle or muscle group or any other biological structure, especially for the deep muscles, e.g. psoas major muscle, and the diaphragm. The method may stimulate other biological structures, e.g. selective stimulation of the particular muscle groups for improving their functionality or for generating a contraction pattern from the muscle group for improving the efficiency of the movement or generating the muscle memory.
According to another aspect of this invention the method may be used for magnetic field stimulation by pulsed magnetic field at repetition rates above 50 Hz, 100 Hz, 150 Hz, or 200 Hz are favourable mainly for treatment of denervated muscle. Denervated muscle lacks the ability of conscious contraction due to a lesion or nerve degradation caused by e.g. polio or trauma, so that the signals from the central neural system are not received. The muscle loses the ability of contraction and flexibility and it atrophies. Effects of muscle atrophy are visible just after three weeks of inactivity.
The stimulation of denervated muscle is based on the adaptability of health motor unit for the raising magnetic flux density. Denervated muscle lacks an ability of adaptation to raise induced electric stimulus as in a normal healthy muscle. Hence the denervated muscle is stimulated by low magnetic flux density.
The stimulation results in an at least partial contraction of denervated muscle and the contraction of healthy muscle is eliminated or minimized.
The stimulation signal may consist of several impulses 61 called burst and a time period with no stimulation. The number of pulses in one burst varies in range of at least 2 pulses to thousands of pulses. The envelope may consist of stimulation signals with various burst frequencies, e.g. 5, 10, 20, 50, or more Hz. The above defined method may be used for therapy, mainly for treatment of denervated muscle. Further the envelope may consist of several periods of stimulation signal of different repetition rates. Therefore the modulation of the signal is in repetition rate domain. In yet another approach the envelope may be modulated by combination of repetition rate domain and magnetic flux density domain.
Envelope may be generated by time-varying magnetic field of varying peak magnetic flux density hence the process is called magnetic flux density modulation (MFDM). The principle of MFDM is described in
Alternatively the envelope may be generated in repetition rate domain hence the process is called repetition rate modulation (RRM). The principle of RRM is described in
According to still another aspect of the application, envelope may be generated in impulse duration domain. The principle of impulse duration modulation is shown in
The modulation approaches are not limited by exemplary waveform. Therefore the envelope may be rectangular, square, saw-tooth, trapezoidal, sinusoidal, exponential etc. Person skilled in the art of neurology and/or physiotherapy may modulate various envelopes and/or envelopes combination.
The application is not limited to use the only single modulation approach. In the preferred application any combination of the upper mentioned approaches may be used.
In an alternative application the neural structure may be stimulated by rectangular or increasing shaped envelope as well.
According to another aspect of the application in neural system diagnostics, the neural structure may be stimulated by single pulses or rectangular shaped envelope, and by increasing shaped envelope. Both envelopes are used for determination of minimal magnetic flux density value sufficient to induce at least partial muscle contraction. The envelope duration may last 1 second. After the determination of both magnetic flux densities values, the level of muscle denervation may be calculated.
An essential principle of magnet therapy used for biological structure stimulation is the influence of the magnetic field on the cell. The cell membrane is polarized due to the induced electric current. One of fundamental phenomenon of electric current in biological tissue may be an action potential occurrence, a transfer of neural excitation and/or a partial or full muscle contraction may be induced. Additionally, the effect of the generated action potential may modulate a painful stimulus transmission, providing a pain management effect.
According to still another application of the invention, the neural structure stimulation by time-varying magnetic field may be used for pain management. In general, the method is focused on neural structure stimulation by time-varying magnetic field of repetition rate at least 100 Hz and/or magnetic flux density sufficient to induce and/or modulate an action potential in a stimulated neural structure.
According to one approach of the aspect of the application in pain management, the neural structure may be stimulated by an envelope created by higher repetition values e.g. exceeding 100 Hz, more preferably at least 150 Hz, even more preferably at least 200 Hz, most preferably at least 250 Hz, or up to 700 Hz. The envelope may be generated with predefined repetition frequency and/or shape.
According to another aspect of the application in pain management, the neural structure may be stimulated by time-varying magnetic field at repetition rate in the range of 80 to 120 Hz, more preferably 90 to 110 Hz, even more preferably 95 to 105 Hz, most preferably around 100 Hz, with magnetic flux density inducing at least below-sensory-threshold stimulus or more preferably at least sensory-threshold stimulus following the application and indication. The method may stimulate the large diameter neural fibers. In general, time-varying magnetic field of repetition rate around 100 Hz with magnetic flux density inducing at least sensory-threshold stimulus is used preferably for pain relief effect.
According to another approach of the aspect of the application in pain management, the neural structure may be stimulated by a time-varying magnetic field to induce electric current of random repetition rate fluctuation around a predefined repetition rate. In the preferred application the repetition rate fluctuates at least 5%, more preferably at least 15%, most preferably at least 30% or up to 50%, the magnetic flux density is sufficient to induce at least sensory-threshold stimulus, more preferably at least over-sensory-threshold stimulus of the neural structure. The neural structure is not able to adapt for the stimulation by time-varying magnetic field since the repetition rate varies. Additionally, the magnetic flux density may be adjusted during the time.
According to still another aspect of the application in pain management, the neural structure may be stimulated by time-varying magnetic field for alleviating the pain via spinal cord and/or spinal nerve stimulation. The aspect of the application may be based on the pattern theory of pain perception. The time-varying magnetic field may be delivered to the target area of backbone and/or spine. Specifically, the method exploits benefits and pain alleviating effect of stimulation with repetition rate at least 125 Hz, more preferably at least 135 Hz, most preferably around 145 Hz or up to 170 Hz. The magnetic flux density is sufficient to induce at least motor-threshold stimulus, more preferably below-noxious-threshold stimulus. Additionally, during the application at least partial muscle contraction may occur hence the local perfusion may increase. Still another benefit of the presented aspect may be myorelaxative effect, long lasting analgesic effect which may be used e.g. for alleviating pain after injuries, in orthopaedics, rheumatology, migraine, headache, neck pain, lumbago, pain of upper or lower extremities and improving the perfusion of itself. Furthermore, various pain syndromes may be treated by the present method.
According to still another aspect of the application in pain management, the neural structure may be stimulated by time-varying magnetic field at repetition rate of at least 160 Hz, more preferably at least 170 Hz, most preferably around 180 Hz, or up to 250 Hz. The present method may be based on gate-control theory of pain. In the preferred application the impulse duration lasts 500 μs at repetition rate around 180 Hz. Optimal magnetic flux density is sufficient to induce at least motor-threshold stimulus, more preferably below-noxious-threshold stimulus. The magnetic flux density may be adjusted following the patient's needs based on the sensitivity of a patient and the depth of the stimulated neural structure. However, the minimal magnetic flux density exceeds 0.1 T, more preferably 0.5 T, even more preferably 1 T, most preferably up to 7 T to induce the at least one action potential. Benefit of the present method is myorelaxative effect. According to one approach of the aspect of the application in myorelaxation, the neural structure may be stimulated by time-varying magnetic field at repetition rate in the range of 30 to 150 Hz, more preferably in the range of 50 to 100 Hz. The time-varying magnetic field is preferably modulated to prevent the neural structure to adapt the magnetic stimulation. The magnetic flux density is sufficient to induce at least over-sensory-threshold stimulus, more preferably motor-threshold, even more preferably over-motor-threshold stimulus
According to still another approach of the aspect of the application in pain management, the neural structure may be stimulated by trains 1601 of several pulses 1602 and time with no stimulation after the train 1601. The group of several pulses 1601 and the time with no stimulation is called burst 1604. Therefore one burst 1604 consists of the only one train 1601 and time with no stimulation 1603. The train 1601 preferably consists of at least 2 pulses, more preferably 5 pulses, even more preferably tens pulses or up to hundreds pulses; repetition rate of the pulses 1602 is at least 100 Hz. The burst repetition rate may vary following the patient's needs. In the preferred application the burst repetition rate vary from 1 to 10 Hz. The number of pulses 1602 in train 1601 and/or the time with no stimulation may vary following the patient needs.
Magnetic stimulation at high repetition rates according to proposed invention is further applicable for the effect of myorelaxation. The repetition rate of at least 100 Hz, 110 Hz, 120 Hz, or 130 Hz may be used for the purpose of the muscle stimulation.
One of the myorelaxation approaches is non-paralyzed muscle adaptation to high repetition rate of stimuli. The magnetic flux density is sufficient to induce current in the biological structure causing motoric intensity or over-motoric intensity at the beginning of the application and it becomes below-motoric intensity after several minutes at constant magnetic flux density since the non-paralyzed muscle can accommodate for the stimulus of constant repetition rate. The impulse time duration is in at least tens of μs, more preferably at least 250 μs or 500 μs. The time duration of a pulse is at least 1 ms, 2.5 ms or 5.5 ms. A repetition rate of pulses around 180 Hz is highly effective. A temporary reflex adjustment of hypertonic muscles or muscle groups is achieved by the application of magnetic stimulation thereafter myorelaxation is provided.
Further application of magnet therapeutic method using sufficient magnetic flux density at high repetition rates over 100 Hz is focused especially on spastic muscle and its trigger point. The method proposes stimulation of muscle hypertonia of the overloaded muscle fibres to relieve a local spasm (the hypertonia in stimulated muscle fibre is relieved). The method affects the muscle insertion as well. The method may even affect the whole muscle group for specific movement.
The stimulation by pulsed magnetic field is divided into two separate periods. The neuromuscular plate is stimulated by pulsed magnetic field during the first period. The magnetic flux density is sufficient to induce at least motoric intensity of electric current to cause at least partial muscle contraction in the stimulated biological structure. The muscle is activated by isometric contraction and sedation follows. The most reactive fibres are selectively inhibited. During the second period the repetition rate is increased to at least 100 Hz, 150 Hz, or 200 Hz. The muscle is relaxed due to high repletion rate. The method is used for high-quality relaxation of at least one muscle fibre.
The method may be used also in sport medicine for stretching of athletes before a performance and muscle relaxation after the performance, thereafter it significantly contributes to muscle regeneration. Further applications are treating for muscle imbalance or muscle relaxation caused by overload, pain relief or elimination and preparation the muscle for physical activity.
The present method may also be used for functional joint blockade treatment. A joint may include muscular structure providing the movement of the joint, joint itself including synovial fluid. Functional joint blockade may be caused by spastic muscles in the vicinity of the joint whose secondary effect is pain. The most common functional joint blockades are in the backbone. These can cause vertebrogenic problems, headache and backbone pain, migraine, perfusion ailment resulting to dizziness, backbone sharp pain directing to limbs, visual insufficiency, tinnitus, toothache or earache etc. The scoliosis, sacral pain (even after fractures), weakness of pelvic floor muscles and incontinence, urine retention or constipation or functional sterility may also be treated by treatment of functional joint blockade.
For the purpose of functional blockade treatment and joint movability improvement the preferred repetition rates may be at least 50 Hz, 60 Hz, 70 Hz or 100 Hz, magnetic flux density at least 0.2 T, 0.4 T, 0.5 T, or at least 1 T and up to 7 T.
Formerly the functional joint blockades were treated by manual positioning, traction, mobilization of the soft tissues, reflex therapy or even pharmacologically. The present method achieves at least partial muscle contraction in the vicinity of the joint, e.g. backbone, by stimulation of neuromuscular plate by pulsed magnetic field at low repetition rate and high magnetic flux density providing at least partial muscle contraction. The joint contact surfaces are moved and the joint is moved due to at least partial muscle contractions of muscles in the vicinity of the joint, e.g. the muscles in the vicinity of the backbone are represented by rotators which causes local microrotations of the backbone. The functional joint blockade is unblocked via muscle mobilization by mechanical approach.
Still another approach of the present method is affecting the rheological properties of synovial fluid by pulsed magnetic field. The total effect of this method may be synergic. Although the method is explained on example of backbone functional joint blockade, the application of the method is not limited to the backbone. A person skilled in anatomy or physical therapy is able to apply the method for any other joint provided by sufficient amount of neuromuscular structures in vicinity. The present method may be preferably used in combination with analgesic methods. It is very convenient to use the present method in combination with method providing myorelaxation since the functional joint blockade is caused by spastic biological structures in vicinity.
All the described methods of stimulation provide trophotropic, anti-oedematous or placebo effect which contributes to the patient's health state and comfort. Local metabolism may be increased as well.
The values of magnetic flux density and repetition rate are cited in several preferred applications since the perception of the stimulation is subjective. Nevertheless the magnetic flux density and repetition rates are not limited by the recited values. A person skilled in physical therapy is able to repeat and apply the therapy methods adjusting the magnetic flux density or repetition rate following the patient's needs.
A person skilled in the physical therapy is able to use various envelopes of the stimulation signal and waveform, e.g. pulse, sinusoidal, rectangular, square, triangular, saw-tooth, trapezoidal, exponential etc. for the purpose of muscle stimulation. The invention is not limited to recited shapes of stimulation signals.
Stimulation signal of biological structure by pulsed magnetic field following the recited methods may be but not limited to continuous, pulsed, randomized, burst. The pulse may be but not limited to symmetric, asymmetric, most preferably biphasic. As used here, proximate to includes in actual contact with the skin of the patient.
In the methods described above, the patient is seated on a patient supporting means maintaining the patient in sufficiently seated position such as a chair or the patient is in sufficiently horizontal position such as supine, prone or lateral position on suitable patient supporting means, e.g. a treatment table or a bed. One or more applicators providing the magnetic stimulation are positioned adjacent to the patient, or in contact with the patient's skin. Generally, the patient's head, torso and limbs are unrestricted, i.e. the patient is free to move and no part of the patient is secured, e.g. strapped, to the patient supporting means. The applicator or applicators are generally placed near the patient, but may not be attached to the patient, so that no part of the treatment apparatus, i.e. one or more applicators and the patient supporting means is attached to the patient and does not restrain or guide a movement of any part of the patient. The magnetic stimulation typically does not cause the patient to move continuously, although some movement may occur via muscle contraction, during certain treatments.
The methods described above do not involve exertion or voluntary contraction of muscle. Rather, the patient is idle and in a relaxed state. In some applications the methods may be used to treat any healthy tissue, and the methods may be used with only magnetic stimulation alone, without any other form of stimulation.
As used here muscle means a single muscle or a group of muscles. Actively moving means physically moving any part of the patient via external apparatus exerting physical force on the patient.
The present method is not limited to be used independently. For enhancing the result the method may be used in combination with other conventional non-invasive and/or invasive aesthetic medicine method.
Skin is composed of three basic elements: epidermis, dermis and hypodermis or so called subcutis. The outer and also the thinnest layer of skin is the epidermis. The dermis consists of collagen, elastic tissue and reticular fibers. The hypodermis is the lowest layer of the skin and contains hair follicle roots, lymphatic vessels, collagen tissue, nerves and also fat forming a subcutaneous white adipose tissue (SWAT). The adipose cells create lobules which are bounded by connective tissue, fibrous septae (retinaculum cutis).
Another part of adipose tissue, so called visceral fat, is located in the peritoneal cavity and forms visceral white adipose tissue (VWAT) located between parietal peritoneum and visceral peritoneum, closely below muscle fibers adjoining the hypodermis layer.
A method of treating a biological structure uses a combination of non-invasive methods for enhancing human appearance. The invention utilizes electromagnetic radiation. Methods may be used for targeted remodeling adipose tissue, focused treatment of cellulite, body contouring, skin tightening or skin rejuvenation. The invention relates to focused heating of the target tissue by electromagnetic waves, whereas the effect of focused heating of the target tissue is amplified by the effect of a pulsed magnetic field treatment.
The present invention discloses the advanced approaches in aesthetic applications, e.g. for cellulite treatment and/or body shaping. Combined methods of treatment by electromagnetic field and treatment by magnetic field are used. The electromagnetic field may include treatment by radiofrequency, infrared or optical waves. The magnet treatment may be provided by permanent magnets, electromagnetic devices generating a static magnetic field or time-varying magnetic devices. In the preferred application the treatment by a pulsed magnetic field and radiofrequency treatment may be combined. However the application is not limited by the recited combination so the combined method may include magnet treatment and any treatment by electromagnetic field, e.g. light treatment, IR treatment or treatment by radiofrequency waves, e.g. microwaves, short waves or long waves.
The energy source for the magnetic and/or light treatment device may be preferably external, e.g. a plug. Alternatively the energy source may be incorporated in the device, e.g. a battery.
Magnet treatment in combination with radiofrequency treatment may be represented by two independent treatment devices, e.g. one treating the target structure by radiofrequency waves and the second treating the target structure by magnetic field. Both devices may have a separate applicator for treating the target structure, or one applicator may be used by at least two devices, i.e. the applicator may be modular for a plurality of devices.
The aesthetic treatment device may include at least one HF frequency generator for providing energy for radiofrequency treatment and for providing energy for magnet treatment. In an alternative embodiment, the device may include at least one HF frequency generator for providing energy for radiofrequency treatment and at least one other independent frequency generator for providing energy for magnet treatment. The device may include plurality of applicators for providing separate radiofrequency or magnet treatments to the patient.
In alternative embodiment the applicator may provide a combination of radiofrequency and magnet treatment. In one embodiment, the applicator may include at least one radiofrequency electrode for providing radiofrequency treatment and at least one coil for providing magnet treatment. In another embodiment, the applicator may include at least one electrode for providing radiofrequency treatment and at least one coil providing magnet treatment, wherein the at least one RF source provides energy for both at least one electrode and at least one coil.
In still another embodiment the at least one RF source may provide the energy for the at least one coil providing magnet treatment wherein the at least one coil may be used as the at least one electrode. The essence is the far different stimulation frequencies which are used for RF treatment and magnet treatment. The coil in the high frequency field is similar to the electrode. This enables the coil to be the electrode for radiofrequency treatment. In the preferred embodiment a flat coil may be used as the electrode.
The frequencies for the radiofrequency treatment may be in the range of ones of MHz to hundreds of GHz, more preferably in the range of 13 MHz to 3 GHz, most preferably around 13.56 or 40.68 or 27.12 MHz or 2.45 GHz. The term “around” should be interpreted as in the range of 5% of the recited value.
Alternatively the RF treatment may be in the range of hundreds kHz to ones MHz, more preferably in the range of 250 kHz to 1 MHz, even more preferably in the range of 400 to 600 kHz, most preferably in the range of 450 to 550 kHz. Such a RF treatment may provide a heating of the target biological structure, e.g. at least one muscle fiber, muscle or a tendon, to provide relaxation effect.
The combination of the recited method may improve currently used applications in various aspects and the effect of the treatments may be significantly enhanced. The application of a radiofrequency electromagnetic field is combined with application of a magnetic field applied before, simultaneously or after the radiofrequency treatment. The magnetic field may be generated by a permanent magnet or electromagnet. The magnetic field may be constant in time or in the preferred application the magnetic field may be time-varying, more preferably a pulsed magnetic field may be used. The application of a magnetic field induces many benefits for radiofrequency treatment, such as applications inducing at least partial muscle contraction, myorelaxation effect or analgesic effect. The perfusion or metabolism may be improved as well.
The at least partial muscle contraction may induce enhanced effects on adipose tissue reduction by catabolism of the adipose tissue and burning energy from adipose tissue. The total adipose tissue reduction effect is enhanced by radiofrequency treatment.
Additionally, the at least partial muscle contraction may improve a blood flow and/or perfusion in the treated area. The improved blood flow may be caused by activation of muscle pump and/or by the muscle necessity of more oxygen due to the at least partial contraction. Due to increased blood flow and/or local perfusion, the risk of overheated muscle is limited or even eliminated. Further the homogeneity of the thermal field induced by thermal effect of radiofrequency treatment may be significantly enhanced and/or the temperatures may be well-balanced/compensated in the target treatment area. Still another benefit is prevention of creation any hot spot caused by steep thermal gradient.
Further the at least partial muscle contraction may improve the movement of lymphatic vessel and the lymph flow may be improved.
Due to improved blood flow, perfusion and/or lymph flow the metabolism may be improved. Additionally, the effect of radiofrequency treatment may be enhanced by improved metabolism, e.g. cellulite treatment, body shaping and/or contouring, skin tightening or skin rejuvenation. Further benefit may be reducing or eliminating the risk of panniculitis or local skin inflammation since any clustering of the treated adipocytes may be prevented by the improved metabolism. The improved blood and/or lymph flow may contribute the removing of the adipocytes. The removing of the adipocytes may be promoted by higher number of cells phagocytosing the adipocytes as well. Synergic effects of magnet and RF treatment significantly improves metabolism. Therefore the possibility of adverse event occurrence is limited and treatment results induced by the present invention are reached in shorter time period.
In the preferred application the RF and/or magnetic field may be modulated. In the most preferred application both stimulation signals are modulated. The magnetic stimulation may be modulated in the magnetic flux density domain, repetition rate domain, or impulse duration domain, to provide different treatment effects and to prevent adaptation of the target biological structure. The radiofrequency treatment may be modulated in the frequency domain, intensity domain and/or time domain to reach the most complexity and/or efficiency of the target treated biological structure. The modulation in the time domain may be changing the active and passive periods of stimulation, e.g. the radiofrequency treatment may include period with no stimulation, i.e. the radiofrequency treatment is not continual but the treatment is provided in pulses. The periods of no stimulation may vary and may be adjusted by the operator. Due to modulation during the treatment, different target biological structures may be treated in the different depth.
The application may be contact or the preferred application of the invention the treatment may be applied contactless. Contactless application may avoid all biocompatibility factors which may occur during contact treatment. In the most preferred application the treatment may be provided by self-operated device. Hence the continual surveillance and/or control by the operator is not essential for correct and/or safe operation of the treatment device. Self-operated treatment may be provided by a hand-held applicator or the applicator may be fixed to stand-alone device. The self-operated treatment may be also enabled using various types of sensors in communication with the device for monitoring the treatment and/or the patient. The at least one sensor may be e.g. reactive sensor, electrochemical sensor, biosensor, biochemical sensor, temperature sensor, sorption sensor, pH sensor, voltage sensor, sensor for measuring distance of applicator from the patient surface and/or from the treated area, position sensor, motion detector, photo sensor, camera, sound detector, current sensor, sensor for measuring of specific human/animal tissue and/or any suitable sensors measuring biological parameters and/or combination thereof such as sensor for measuring dermal tensile forces, sensor for measuring the activity of the muscle, muscle contraction forces, tissue impedance or skin elasticity.
Further the homogeneity of the treatment may be improved by several approaches. A first approach may be represented by a moveable applicator providing the dynamic treatment to a larger target area. The dynamic treatment improves the homogeneity of applied treatment energy and additionally due to larger area the effect is uniform and/or well balanced. Static positioning of the applicator may be used as well. Another approach of improving homogeneity may be represented by using a bolus. The bolus may provide improved transmittance of the electromagnetic energy to the treated biological structures. Additionally, the bolus may prevent occurrence of hot spots within the treated area; the bolus may provide constant temperature to the target treated surface area; or the bolus may increase the homogeneity of the radiofrequency waves application by providing a homogenous medium for electromagnetic waves propagation not being influenced by the interface of the target treated area and an air. The bolus may profile the electromagnetic field to enhance the effect of the treatment. In still another approach an air gap may be between the applicator and the patient.
The treatment by magnetic and/or electromagnetic field may be in continuous or discrete modes. In one application the magnetic treatment may be applied in continual mode with no pauses and the electromagnetic treatment may be applied in pulsed mode to provide improved adipose tissue reduction caused by natural process and by the increased temperature. In another application the electromagnetic treatment may be applied continuously with no pauses and the magnetic treatment may be applied in pulsed mode to provide improved thermal reduction of adipose tissue and by improved metabolism due to improved blood flow. Both modes may be combined in various treatment sequences.
In the preferred application the treatment is started at the moment when the target biological structure reaches the predetermined temperature. The temperature in the target tissue may be up to 80° C., more preferably in the range of 37 to 60° C., even more preferably in the range of 40 to 45° C. The temperature may be adjusted based on the intended use, e.g. adipose tissue reduction, collagen production or muscle contraction. In an alternative application the intended use may be coagulation and/or ablation. The temperature in the target biological structure may be measured by invasive method, e.g. using an invasive probe; or by contact method, e.g. using thermocouple sensor; or by contactless method, e.g. using infrared sensor or camera. The temperature of the target biological structure may be determined by a mathematic method. The sensor for measuring the temperature in the target biological structure may be attached to the applicator.
A benefit of the application of magnet treatment and electromagnetic treatment may be causing an analgesic effect of the application and providing a possibility of treating a patient with higher sensitivity for thermal effects induced by electromagnetic treatment, i.e. patients with any predisposition inducing increased thermal sensitivity. The analgesic effect may be induced by magnet treatment by suitable repetition rates and it may be induced immediately during the magnet treatment. The analgesic effect may last up to several hours after magnet treatment. The magnetic flux density of the magnetic stimulation may preferably reach at least motor-threshold intensity inducing at least partial muscle contraction therefore the homogeneity of the thermal field is significantly enhanced.
In one aspect of the invention, the treatment by magnetic field may be applied to the target structure before the radiofrequency treatment to prepare the target structure for following treatment by radiofrequency field. The effect of magnet treatment is to induce at least partial muscle contraction or to stimulate a muscle structure to increase a muscular tonus of the target structure. Both effects may provide a massage effect for the structure within the proximity of the target structure hence the blood and/or lymph circulation may be improved to promote local metabolism. The temperature may be locally increased by the improved blood flow and the target structure may accept the following radiofrequency treatment at significantly higher quality. Additionally, the collagen and/or elastin fibers may be remodeled or restored and/or its neogenesis may be improved to provide a younger, smoother and enhanced skin appearance.
Additionally, previous application may improve acceptability of the electromagnetic field by increasing the temperature of the skin and the transmittance of the electromagnetic field may be improved due to less value of skin impedance. Further the radiofrequency may penetrate deeper target structures relative to treatment without a preceding magnet treatment of the target structure and/or area.
Another benefit may be releasing the adipose tissue in the muscle by muscle contraction and/or by temperature increase causing better liquidity of adipose tissue. Still another benefit of the at least partial muscle contraction may be mechanical breaking large adipose tissue bulks into smaller bulks which may be easier metabolism of the adipose tissue and/or the smaller adipose tissue bulks may be removed faster by the lymphatic and/or blood flow. Due to improved metabolism and/or circulation the cellulite may be treated in a short time and the visual effect on skin appearance may be significantly enhanced.
In another aspect of the invention, the treatment by magnetic field may be applied to the target structure simultaneously with the radiofrequency treatment to improve effects of the electromagnetic treatment inducing heat in the target structure.
The simultaneous application of magnet treatment and radiofrequency treatment may be in two modes: a first mode may generate the magnet impulses while radiofrequency treatment is active or another mode may generate radiofrequency treatment while the magnet treatment is not in an active stimulation period, i.e. the period of magnet treatment and radiofrequency treatment alternates. Both modes amplify the resulting effect of the treatment. Therefore the results are achieved in significantly shorter time than the same results achieved by separate applications of the radio frequency and magnet treatments.
The simultaneous method of magnet treatment and radiofrequency treatment of the target tissue may increase the peak magnetic component of the entire treatment resulting in improved heating of the target structure including containing higher water volume, e.g. skin. Due to increased temperature of skin, the production and/or remodeling of collagen and/or elastin fibers may be improved and the skin may be provided with a younger, smoother and enhanced appearance. The effect of overheating the muscle is reduced by the improved blood flow.
In still another aspect of the invention, the treatment by magnetic field may be applied to the target structure after the treatment by electromagnetic field to enhance and/or contribute to the effects of radiofrequency treatment by influencing the target structure by magnetic field.
The magnetic field may treat the target structure to cause at least partial muscle contraction proximate to the target structure to improve blood flow and provide homogenous temperature distribution at high quality after creating a temperature distribution at lower quality by radiofrequency treatment.
The present device and methods of its operation are related to treatment of a patient by magnetic and/or electromagnetic treatment. The electromagnetic treatment may be particularly radiofrequency treatment. The application of the magnetic and/or electromagnetic treatment may be provided by at least one energy delivery element. The device may be used for treatment or focused remodeling of subcutaneous tissue by reducing number and/or value of lipid-rich cells, cellulite treatment, body shaping and/or contouring, muscle toning, skin tightening, collagen treatment, skin rejuvenation, wrinkle removing, reducing stretchmarks, breast lifting, lip enhancement, treatment of vascular or pigmented lesions of the skin or hair removing.
The essential principle for this device is a fact that the energy delivery element, e.g. a magnetic field generating device such as a flat coil which may be preferably circular shaped, may administer the same function as an electrode if it is provided by the high-frequency signal. Hence the coil may be used to generate a radiofrequency treatment. The reason is that the frequency spectra of low-frequency signal used for generating the magnetic field is far different from frequency spectra of high-frequency signal used for generating the electromagnetic field. The signals from at least one or more preferably two generators may be provided successively, with some overlay or simultaneously due to difference of the frequency spectra. The frequency spectra of high-frequency signal used for generating the electromagnetic field may be in the range of ones of kHz to hundreds of GHz, more preferably in the range of 500 kHz to 3 GHz, most preferably above 1 MHz around 3.4 or 6.7 or 13.56 or 40.68 or 27.12 MHz or 434 MHz or 915 MHz or 2.45 GHz. The frequency spectra of low-frequency signal used for generating the magnetic field impulses may be in the range of 1 to 100 kHz, more preferably in the range of 1.25 to 10 kHz, even more preferably in the range of 2 to 5 kHz, most preferably in the range of 3 to 4 kHz. The low-frequency signal is used for generating impulses of time-varying magnetic field. The repetition rate of the pulses may reach up to 700 Hz, more preferably up to 500 Hz, most preferably in the range of 1 to 300 Hz. The magnetic flux density of the magnet treatment is at least 0.1 T, more preferably at least 0.5 T, even more preferably at least 1 T, even more preferably at least 1.5 T, most preferably at least 2 T, or up to 7 T on the surface of the energy delivery element. The energy delivery element may be integrated within an applicator, such as patient support for maintaining the patient in sufficiently sitting or recumbent position, e.g. a chair or a bed. The energy delivery element may be moveable within the patient support. Alternatively the applicator may be moveable, e.g. it may be attached to an articulated arm or it may be preferably hand-held.
The side of the energy delivery element closer to the patient may be covered by a layer of insulating material such as ceramic or epoxy coating, or bolus. The insulating material may provide electrical insulation of the patient and mechanical protection of the energy delivery element.
In an alternative embodiment the treatment device may include a plurality of HF generators and/or a plurality of LF generators.
In an alternative embodiment the treatment device may include a human machine interface for the patient. The patient may control the power in the treatment hence the patient may control e.g. temperature of the target biological structure or strength of the at least partial muscle contraction. Furthermore the patient may interrupt the treatment before any discomfort feeling may occur.
The power supply may provide energy for the treatment device via the power source 1801. The power supply may be external, e.g. a plug, or it may be integrally included within the treatment device, e.g. a battery. The power source 1801 may communicate with generators 1802, 1803. The power source 1801 may provide energy to electric components of the treatment device, particularly to generators 1802, 1803 or to control unit 1804.

The control unit 1804 may communicate with LF generator. LF generator may provide LF signal to energy delivery element 1806 to generate magnetic treatment. The LF generator 1803 may provide information referred to treatment process to the control unit 1804, e.g. energy loss from one impulse. In an exemplary embodiment the control unit 1804 may send instruction to power source 1801 to provide the LF generator 1803 by the energy amount equaling the energy loss. Alternatively the control unit 8 may control recharge of the LF generator.

In one exemplary embodiment RF energy transfer may be optimized prior to the treatment. In an exemplary embodiment the HF generator 1802 may include an internal power source for adjusting energy for energy delivery element 1806. Alternatively, more than one energy delivery element 1806 may be used. When using two or more energy delivery elements, the at least one energy delivery element may deliver magnetic field, the at least one energy delivery element may deliver electromagnetic field (e.g. radiofrequency field); in still another embodiment each energy delivery element may provide both magnetic field and electromagnetic field (e.g. radiofrequency field) for magnetic and electromagnetic treatment.
The control unit 1804 may be in communication with human machine interface 1805. The human machine interface 1805 may include outputting interface for providing information for the operator and/or the patient. The outputting interface may include audio output, e.g. a speaker; visual output, e.g. a display or any combination. The outputting interface may provide a notification for the operator and/or the patient in a human perceptible form such as beep, flashing light, color change or mechanical signal.
The human machine interface 1805 may include at least one input element, e.g. touch member such as touchscreen, keyboard, control member for adjusting the treatment, for providing the information from operator. The operator may adjust e.g. a treatment protocol or may adjust treatment parameters following the patient's need.
In an alternative embodiment the treatment device may include at least two control units. One control unit may administer HF generator. Second control unit may administer LF generator. In this exemplary embodiment a communication link between both control units may be established.
The energy delivery element may be used as an energy source for another part and/or electric member of the treatment device. The energy delivery element may be used as a part of transformer or antenna. In an exemplary embodiment illustrated in
In an exemplary embodiment the treatment device may include one energy delivery element. The energy delivery element, e.g. a flat coil, may be used for providing magnetic treatment and RF treatment. The energy delivery element may be provided by high-frequency and by low-frequency signal. The RF treatment may be unipolar. The high-frequency electromagnetic field may be radiated to the target biological structure. The applicator may be moveable to increase the homogeneity of the treatment. The scanning movement may be preferably used. Alternatively the movement of the applicator may follow a predetermined pattern corresponding to a treated body part. The movement of the applicator may be manual and/or automatically provided by a manipulating device, e.g. robotic arm or scanning mechanism.
The radiofrequency treatment may be applied by the energy delivery element to the target biological structure in three modes. One mode may be simultaneous application of RF treatment and magnetic treatment. Another mode may be separate RF treatment and magnetic treatment, RF and/or magnetic treatment may be applied in various sequences or it may alternate. Still another mode may be application of RF and magnetic treatment with some overlay. In an exemplary application the RF treatment may be applied prior a magnetic treatment. In another exemplary application the RF treatment may be applied after magnetic treatment.
In an alternative embodiment the treatment device may include a reference electrode to provide a monopolar application of RF treatment by the energy delivery element.

The treatment device may include a mathematic method including at least one of calculation and/or statistic method for monitoring correctness of the treatment and/or for monitoring the heat produced by the treatment device. The mathematic method may monitor at least one characteristic quantity of at least one operation parameter. The mathematic method may be used for determining heat generated by the energy delivery element. The generated heat may be used for additional heating biological structures in proximity. Alternatively, the energy delivery element may be less cooled to reach higher temperature for improved heating of the patient.
The applicator may be statically positioned to a predefined position to treat the target biological structure. Alternatively the applicator may be moveable during the treatment to treat larger area of the patient compared to treatment in static position. The RF energy transfer may be optimized prior to the treatment if the applicator is statically positioned and/or the treatment is provided in contact way. However, the continual optimizing of the energy transfer may be preferred for providing optimal and/or highly effective treatment to shorten the treatment duration, to improve the treatment effect and/or to achieve the desired results in shorter time period. Moreover the continual energy transfer optimizing may eliminate incorrect energy transfer caused by patient movement, e.g. caused by breath, and/or change of physiological conditions, e.g. caused by sweat, improved blood perfusion or increased temperature.
The treatment device may include a plurality of energy delivery elements, e.g. two, three, four or more. However, the even number of energy delivery elements may be used in the preferred embodiment.

In exemplary embodiment RF energy transfer may be optimized prior to the treatment. However, the continual optimizing of the energy transfer may be preferred for providing optimal and/or highly effective treatment to shorten the treatment duration, to improve the treatment effect and/or to achieve the desired results in shorter time period.

In an alternative embodiment the exemplary treatment device may include one LF generator. According to alternative embodiment only one generator providing low and high frequency may be used.
Alternatively, the transmatch may be a incorporated in balun. The energy transfer may be optimized by e.g. adjusting transformation ratio.
In still another exemplary embodiment with respect to
The plurality of energy delivery elements may be positioned independently to each other to provide a treatment for the patient following the patient's needs. The position of the energy delivery element may be placed by the operator. The plurality of energy delivery elements may be in a plurality of applicators, e.g. each applicator includes at least one energy delivery element.
Alternatively the plurality of energy delivery elements may be positioned dependent to each other, preferably in a predefined pattern. The position of the plurality of the energy delivering elements may provide a treatment characterized by a phase shift.
The treatment device may include a plurality of applicators. Each applicator may include at least one energy delivery element. The applicator may be moveable during the treatment, the energy delivery element may be movable within the at least one applicator as well.
Alternatively the plurality of energy delivery elements may be positioned within one applicator having form of mechanical holder. The shape of the applicator having form of mechanical holder may be adjustable, e.g. the applicator may include at least one moveable part. In a preferred embodiment the applicator having form of mechanical holder may provide spatial arrangement of the energy delivery elements in one axis, two axes or three axes and/or provide tilting and/or rotation. The applicator having form of mechanical holder may provide fixation of the at least one energy delivery element in one position.

The positioning member may include a buckle for adjusting the length of the belt. The applicator may be placed within predefined locations of the belt. Alternatively the applicator may be shaped to be moveable along the positioning member, e.g. the shape of the applicator may be preferably concave, e.g. V-shaped or U-shaped. The positioning member may be inserted itself into the concavity of the applicator. The position of the applicator may be adjusted by limited movement along the positioning member because the positioning member may be used as guiding member. However, the applicator may not be fixed to a particular static position. The position of the applicator may be dynamically adjusted during the treatment following the patient's needs. The position of the applicator may be adjusted manually by the operator, or automatically by the treatment device. In one exemplary embodiment a plurality of applicators may be used for treating larger body part, e.g. buttocks, abdomen or thigh.
Alternatively, the at least one energy delivery element, e.g. a coil, may be positioned below the at least one electrode. The energy delivery element may be positioned in between the electrode and the patient.
The at least one energy delivery element may influence at least one another energy delivery element while using the plurality of energy delivery elements. The correct treatment may be controlled via the mathematic method used for monitoring the at least one characteristic quantity of the operation parameter. The mutual positon of the energy delivery elements may be evaluated by the mathematic method as well. Hence the mathematic method may prevent providing the patient with incorrect treatment caused by incorrect position and/or orientation of at least two energy delivery elements. Furthermore the mathematic method may prevent the treatment device from affecting any conductive parts by the generated treatment, e.g. an additional heat may be generated.
The mathematic method may be further used for determining temperature and/or heat generated by at least one energy delivery element. Hence the mathematic method may be used for controlling a cooling of the energy delivery element, e.g. flow of the cooling media may be regulated. The heat generated by the energy delivery element may be further used for heating the patient.
The present device and method use a combination of non-invasive, preferably contactless, applications of different methods for enhancing human appearance. Particularly, the present invention uses a combined treatment by time-varying magnetic field and optical waves.
The treatment is defined by application of electromagnetic waves of wavelength in the range of 635 to 1100 nm, with maximal power flux density up to 100 W/cm2. Alternatively, in the case of pulse light, the power flux density may be up to 100 W/cm2 with light pulses lasting up to 300 ms, however, preferably in the range of 1 to 20 ms. Optical treatment may be used for inducing heat generation within the adipose cells over physiological temperature.
The treatment by optical waves may be combined with application of magnetic treatment inducing at least partial muscle contraction.
The presented methods enable aesthetic applications providing significant reduction of number and/or volume of adipose cells and cause circumferential reduction i.e. a reduction of the size of the treated body area. Furthermore, the treatment method induces at least partial muscle contraction to provide muscle toning, muscle shaping, body contouring, body shaping or skin tightening effect. Additionally, strong muscle contractions at high repetition rate may cause mechanical movement of all the layers in proximity of the contracted muscle. The method therefore may cause remodeling and/or neogenesis of the collagen and elastin fibers.
Optical treatment may selectively heat the target biological structure. Hence optical treatment may remove and/or remodel adipose tissue. Before/after, with some overlap or simultaneously the magnetic treatment of the target biological structure may induce at least partial muscle contraction within the target biological structure to remodel the adipose tissue by natural adipose tissue catabolism. Adipose tissue catabolism may be caused by apoptosis and/or necrosis of the adipocytes. The muscle contraction caused by induced eddy current is equivalent to a natural contraction. The adipose tissue may be reduced in natural way. Additionally, the muscle may be toned and/or shaped in a natural way. Therefore the effect resulting in body shaping and/or contouring may be significantly improved.
The present methods provide advanced approaches in aesthetic applications. Combined methods of treatment by optical treatment and treatment by magnetic field are used. The optical treatment may include treatment by optical waves. The magnet treatment may be provided by permanent magnets, electromagnetic devices generating a static magnetic field or preferably by magnetic devices generating time-varying magnetic field. In the preferred application the method may combine treatment by a pulsed magnetic field and optical treatment. The application is not limited by the recited combination so the combined method may include magnetic treatment and any treatment by electromagnetic field such as radiofrequency waves, e.g. microwaves, short waves or long waves.
The basic parts of the optical irradiation system include a hardware panel and an optical waves generating device or multiple optical waves generating devices. The optical waves generating device may be arranged in an array. The optical waves generating devices may be attached to each other or alternatively be individually mounted on dedicated supports. A scanning system may also be one of the options.
At least one optical wave generating device and a magnetic field generating device are provided. An optical treatment device may include at least one energy source and/or connection to the energy source, a hardware panel for controlling the optical treatment device and an optical waves generating device. Non limiting examples of optical waves generating device that may be used include light emitting diodes, lasers, laser diodes, different types of lamps and filtered lamps or combinations thereof. The treatment device may include at least one optical waves generating device, more preferably a plurality of optical waves generating devices of wavelength from ultraviolet, visible and infrared spectrum ranges. The wavelength may be in the range of 190 to 13000 nm, preferably in the range of 290 to 3000 nm, more preferably in the range of 400 to 1500 nm, even more preferably in the range of 550 to 1450 nm, particularly wavelengths about 915, 1064, 1208 and 1715 nm may be used.
The plurality of optical waves generating devices may generate optical waves simultaneously. The plurality of generated optical waves may interfere. Alternatively the plurality of optical waves generating devices may generate a plurality of independent optical waves at different times, preferably in sequences. The plurality of optical waves generating devices may be arranged in a predefined pattern within an applicator, e.g. in an array or a matrix.
The optical treatment applicator may be preferably external (e.g. hand-held). Alternatively, the optical treatment applicator may be an integral part of the optical treatment device (e.g. chair/bed implemented). Additionally, optical delivery elements, such as optical waveguides, light tubes or optical gel, may be used.
The magnetic treatment applicator may be an integral part of the treatment device, or it may be preferably external part of the treatment device (e.g. hand-held), alternatively the magnetic treatment applicator may be an integral part of the magnetic treatment device (e.g. chair/bed implemented).
According to one embodiment the magnetic treatment and optical treatment may be provided by at least two separate devices, i.e. at least one device for administering the magnetic treatment and at least one device for administering the optical treatment. The optical treatment may be applied to target biological structure prior, after or with some overlay with magnetic treatment. Alternatively optical treatment may be applied simultaneously with magnetic treatment. The time consequences of the treatment are described below.
In an alternative embodiment the at least one optical waves generating device may be in the treatment device. The optical waves may be delivered to the applicator and/or to the target biological structure by a waveguide.
According to another embodiment the magnetic treatment and optical treatment may be provided by one device. The combined treatment provided by one device may be administered by at least one applicator.
In an alternative embodiment the at least one optical waves generating device may be in the treatment device. The optical waves may be delivered to the applicator and/or to the target biological structure by a waveguide.
In an alternative embodiment the optical waves generating devices may be in the treatment device. The optical waves may be delivered to the applicator and/or to the target biological structure by a waveguide.
In an alternative embodiment the optical waves generating devices may be in the treatment device. The optical waves may be delivered to the applicator and/or to the target biological structure by a waveguide.
In an alternative embodiment the at least one optical waves generating device may be in the treatment device. The optical waves may be delivered to the applicator and/or to the target biological structure by a waveguide.
According to still another embodiment the magnetic field generating device may be used as an energy source for providing energy to another part of the treatment device, e.g. an optical waves generating device such as light-emitting diode (LED).
Biocompatibility issues or hot spot generation may be overcome by transmitting electromagnetic energy into the target biological structure without physical contact with the patient. Contactless application of magnetic and/or optical treatments may provide sufficient passive cooling of the biological structure by circulating air.
In some indications, it may be advantageous to treat deeper adipose tissue by magnetic field simultaneously with the treatment of more superficial layers of the skin by optical waves.
An air gap or bolus material with high air permeability may be placed between the skin and the applicator. The material may be preferably transparent to the optical waves. This arrangement uses the human thermoregulatory system for cooling and avoids the need of artificial cooling of the skin. Optionally, the skin may be cooled via a stream of chilled or ambient temperature air. The human thermoregulatory system enables perspiration and other body fluids to evaporate and cool the surrounding skin. The application of electromagnetic waves is contactless. Therefore sweat accumulation and/or hot spot creation are avoided. Use of cooling fluids or gels is not necessary but may be optionally used. Cost of the treatment is reduced and patient comfort is improved. The applicator may be in direct or indirect contact with patient's skin. A bolus device may be used for providing indirect contact of the applicator with the target biological structure. A bolus may be filled with a material, preferably a fluid, influencing the propagation of the electromagnetic waves and/or homogenizing the temperature distribution of the patient's skin. Alternatively the bolus may deliver the electromagnetic waves to the target biological structure, e.g. a waveguide.
Cooling may be provided by positioning an air moving device proximate to the skin. The air moving device may be attached to or implemented into the applicator. Air moving device may be any kind of fan, ventilator or blower. The blower may include an air tube connected to air source for moving air through the air tube to the patient's skin. The air source may alternatively be cooled to provide cooled air. Alternatively, air suction may be also used as an active cooling method.
One or more applicators may move in the vicinity of the patient's body. The movement may be provided in various speed and/or acceleration. It may be moved in at least one direction, e.g. longitudinal, vertical, transversal or different axis and/or by rotational movement around any direction. Plurality of applicators may move in synchronized, randomized and/or independent manner. At least one applicator of the plurality of applicator may be static.
The homogeneity of treatment may be provided by the movement of the applicator. In one exemplary embodiment the applicator may move over and/or in different angle to the patient by rotational movement. In another exemplary embodiment the applicator may move in the vicinity of patient's skin. In still another exemplary embodiment the applicator may move to focus the treatment.
The movement of at least one applicator may provide a treatment pattern. The pattern may be, e.g. linear, wavy, circular, elliptical, zigzag, polygonal, oval, irregular and/or any combination thereof. In one exemplary application the at least one applicator may be positioned to the vicinity of thighs and the effect of treatment may be limited to these parts. In another exemplary application the at least one applicator may be positioned over the patient's abdomen to treat e.g. adipose cells.
The movement of the applicator may also provide a treatment to large body part, e.g. buttocks, abdomen or thigh.
The sensor may be connected with the hardware panel for controlling the optical treatment to adjust the power flux density applied to the biological structure to maintain the temperature of the target biological structure within treatment range. The temperature sensor also prevents the patient from any thermic damage.
Optical treatment may be used for remodeling, reducing the volume and/or number of adipose cells, body contouring or tightening skin, skin rejuvenation, wrinkles and/or stretch mark reduction, mole mark removal, tattoo removal, enhanced skin tightening, hair removal, treatment of vascular lesions, acne treatment, sweating reduction and other appearance improving and/or pain relief treatment without contacting the skin. The treatment may optionally be performed simultaneously or consecutively during the same session.
The commonly targeted skin chromophores are hemoglobin, melanin, carbon or tattoo ink. Alternatively water may absorb the optical waves. Each chromophore has unique absorption spectrum. The wavelength of the optical wave should match one of the absorption peaks of the targeted chromophore. The lasers or laser diodes work usually in pulse regime in these applications. The optical energy absorbed by the chromophore is converted to thermal energy thereby destroying the targeted cells. Selection of the best adapted wavelength, power and pulse duration allows achieving optimal effect on targeted biological structure with minimal effect on surrounding tissue.
The application of optical treatment may be improved by application of exogenous chromophores to the target biological structure. The exogenous chromophores may be applied in form of topical lotion, or may be delivered to the target biological structure by micro-invasive or invasive way such as injected.
According to the parameters of the optical waves used, different layers of the skin and different biological structures may be selectively treated. Various wavelengths, powers, pulse durations and repetition rates of electromagnetic radiation are applicable to provide the advantage of vast variability of penetration and absorption parameters. The operator may also adjust the optimum treatment time for each wavelength and the time sequences of treatments by different wavelengths, while some of them may overlap in time. In this way, a tailor-made solution for each patient and each indication is available. The treatment may be highly selective to reduce or avoid damage of the surrounding tissues.
Combinations of a plurality of optical waves generating devices allow performing the treatment of plurality of target biological structures at the same time and/or treating the same target tissue simultaneously by different means, which optimizes the doses of radiation applied. This diversification may also eliminate the risk of overheating, as the optical treatment with parameters leading to no or negligible thermic effect may be used. As a result, the risk of heat damage may be considerably reduced.
If the patient has more imperfections to be treated situated in the same body areas, it is also possible to treat them simultaneously by different types of electromagnetic waves. Each of the electromagnetic waves may be adjusted to optimum parameters for the target biological structure imperfection treatment. Thus the time of patient and of the operator is reduced, reducing the treatment cost.
The optical waves thermal effect may lead to temperature increase in the dermal and the sub dermal tissues also affects the triple-helix structure of collagen fibers contained in such tissues. This may result in remodeling and rejuvenation of collagen, increase of skin density and dermal thickening based on neocollagenesis. Skin tightening may also be achieved. In one aspect, the present methods selectively treat deep human tissue containing low volume of water, such as adipose tissue. Optical energy is provided to the skin by optical waves generating device. Remodeling and reducing the volume and/or number of adipocytes or skin tightening in the targeted areas may change the overall appearance of the body. Therefore it may be used for body contouring, body shaping and cellulite treatment.
Optical energy may be provided to the skin by at least one optical waves generating device in pulse or continuous mode. Optical energy is provided through the skin to the underlying dermal and/or subdermal tissue, without contacting the skin. The radiant energy may be converted inside the target tissue to heat. The radiant energy enables treating of the adipose tissue and/or collagen tissue, accelerating apoptosis and/or cell lysis (e.g. adipose cell), based on amount of energy transmitted to target biological structure. At the same time the triple helix structure of collagen fibers may result in remodeling and/or rejuvenation of collagen, increase of skin density and dermal thickening based on neocollagenesis. In an alternative embodiment the radiant energy enables treating of target tissue resulting e.g. in neocollagenesis without adipose tissue reduction. Target tissue may be remodeled and/or reduced and body contouring and/or skin tightening effect may occur.
Cooling may also be used to modify and to optimally adjust the depth of optical radiation penetration. Light penetration may be enhanced if cooling is used before phototherapy. The effects of heating in terms of light penetration are the opposite.
Optical treatment may treat the same or different skin layers as the magnetic treatment. As mentioned above, optical treatment may also be used for multiple rejuvenation and appearance enhancing applications. Another important indication is drug-free and addiction-free pain relief in many conditions.
Non-limiting examples of optical therapies that may be preferably used in combination with the treatment by magnetic field according to the present invention are: low level light therapy (LLLT), photodynamic therapy (PDT), high power laser therapy (HPLT) or intense pulsed light (IPL). However, the scope of the invention is not limited only to these particular optical irradiation methods. Other electromagnetic waves may be used, e.g. a radiofrequency treatment. The power flux density of the optical wave therapy may be in the range to 0.1-100 W/cm2, more preferably in the range to 0.5-50 W/cm2, most preferably 0.5-20 W/cm2.
Low-level light therapy is one of the methods of non-invasive rejuvenation with no or a very small thermal effect. LLLT may be effective throughout the visible, infrared and near ultraviolet spectrum ranges. The term low level refers the fact that the levels of energy or power densities are low compared to other forms of light treatment such as by lasers, which are applicable for cutting, thermal coagulation or thermal damage, such as ablation. Treatment energies in LLLT are limited to 0.1-20 or a few J/cm2 and/or by a power of 1 mW to 500 mW per optical waves generating device. The depth of penetration of the low level light radiation depends on parameters of the optical waves generating device such as wavelength, operating mode, which may be pulse or continuous, the power output, the probe design and the treatment technique. The depth of penetration where the light still has therapeutic effects should match the depth of the desired zone to be treated. The penetration depth is lower than in HPTL, up to several tens of mm approximately. Due to the low levels of absorbed energy, the treated and surrounding biological structures are not heated and are not damaged. Although many wavelengths may be used, it is advantageous to use at least one beam in the visible spectrum so that the area of application on the patient's body may be easily determined by the operator.
LLLT uses either coherent optical waves generating devices such as lasers or laser diodes or non-coherent light sources including incandescent lamps, gas filled lamps, filtered lamps optimized for a particular wavelength, light-emitting diodes, etc. A combination of any types of optical waves generating devices may be also used, as well as a plurality of optical waves generating devices of the same type.
The photons emitted by the low level optical waves generating devices used in LLLT therapy may be absorbed by endogenous mitochondrial chromophores in skin. Consequently, many processes may be activated, e.g. electron transport, increased adenosine triphosphate (ATP) production, enhanced blood micro-circulation, collagen production increase, dermal matrix remodeling etc. LLLT may thus successfully treat a multitude of conditions that require stimulation of healing, acute/chronic pain relief or restoration of function. LLLT has beneficial effects on wrinkles, scars including acne scars, stimulating the scalp in hair treatment, healing of burns, skin tightening, anti-oedematous effects, regeneration after sport etc. Inflammatory skin diseases such as psoriasis or acne may be also treated by the proposed treatment. In pigmentation disorders such as vitiligo, LLLT may increase pigmentation by stimulating melanocyte proliferation.
LLLT may influence also reduction of number and/or volume of adipose cells. It is believed that the incident optical waves produce transient pores in adipose cells, allowing lipids to leak out into the interstitial space of adipose tissue. If the parameters are appropriate, the pores close upon cessation of the energy application and the cell membrane returns to contiguity. The adipose cells are not destroyed, but temporary opening within the cell's membrane induced by the optical waves may provide a pathway for lipid to exit the cell and in the end also the patient's body. It may leads to the reduction of number and/or volume of adipose cells. This adipose cell number and/or volume reduction may restore proper adipose cells function thereby acting as an anti-diabetes mechanism.
It is advantageous to combine LLLT and magnetic treatment for safe and efficient target biological structure treatment.
While in LLLT the light is absorbed by endogenous cellular chromophores, PDT may be based on introduction of exogenous photosensitizers into the cells which are then irradiated with wavelengths of visible or near infra-red light. Photosensitizer drugs may become activated by one or several types of optical waves. The optimal type of optical waves depends on the target biological structure and the absorption peak of the particular chromophore drug used. PDT optical waves generating devices include laser, intense pulsed light, light-emitting diodes or many visible lights including natural sunlight, etc.
Unlike LLLT HPLT has pronounced thermal effects on the skin. HPLT lasers having an output of 500 mW or greater may be used for this treatment, with energy densities greater than 10 J/cm2. High power allows extremely high penetration of the optical waves, in order of ten centimeters or even more, ensuring that the right dose actually reaches the target biological structure localized deep in the tissue. Laser may be precisely adjusted due to its monochromacy and coherency. Therefore its propagation and targeted biological structure may be finely pre-defined. Research shows that biological structures treated by HPLT are stimulated to increase production of adenosine triphosphate (ATP). Similarly to LLLT, the biological responses to increased ATP production may include reduction of inflammation, reducing scars, increased cell metabolism, improved vascular activity, and accelerated healing. It may improve regeneration after sport. Significant improvements of many post-traumatic pathologies or osteoarthritis have been noted, as well as temporary relief of stiffness and muscle spasms. It is important to note that HPLT also may provide the patients with drug-free and addiction-free acute and/or chronic mediation of pain, by decreasing inflammation and/or swelling and by increasing the release of endorphins and enkephalins. Moreover, if a pulse regime is applied, the wavelength-specific photomechanical wave generated in the tissue may stimulate free nerve endings, thus blocking pain pathways in the nervous systems and bringing immediate pain relief.
High power lasers, laser diodes or intense pulse light sources (IPL) may be also used for treating pigmented targets in the skin by selective photothermolysis. Such high power lasers reaching sufficient power density to vaporize illuminated cells may be gas lasers such as C02 or excimer laser, solid-state lasers such as rubin, Nd:YAG or Er:YAG laser, semiconductor lasers, dye lasers such as Rhodamin 6G laser etc.
IPL may be used also for other skin treatments with therapeutic or rejuvenating effects, sharing some similarities with high power laser treatment. In both cases, optical waves are used to destroy the target. But unlike lasers that use a single wavelength of light which typically matches only one chromophore, and hence only one condition, IPL uses a broad spectrum of wavelengths. When used with filters, it may be adapted to treat various conditions. This may be achieved when the IPL operator selects the appropriate filter that matches a specific chromophore. Such filter may be represented by an optical material filtering e.g. 480 nm, 530 nm, 560 nm, 640 nm or 690 nm.
The optical energy flux density of the IPL treatment may be in the range of 1 and 50 J/cm2, preferably in the range of 2 to 40 J/cm2, more preferably at least 5 J/cm2, or up to 100 J/cm2. The optical waves may be applied continually or in pulses. Pulse width is time duration that the target is exposed to the optical waves, it is measured in milliseconds. Pulse width is shorter than thermal relaxation time of the target, i.e. the pulse width is long enough to allow heating of the target but also short enough that the target is able to cool so that there is no heat buildup in surrounding skin and tissue. The pulse width may be in the range of 1 to 300 ms, preferably in the range of 5 to 50 ms, most preferably up to 30 ms.
Optical waves may penetrate the skin and increase the temperature of adipose cells and thermally damage the adipose cells. Hence the optical treatment may be used for reducing number and/or volume of adipose cells, remodeling treated body parts, or improving the skin appearance. The target biological structure, e.g. adipose cells, may be exposed to increased temperature. The temperature may be in the range of 37.5 to 60° C., more preferably in the range of 40 to 50° C., most preferably in the range of 42 to 47° C., or up 80° C. The damaged adipose cells may be removed by blood and/or lymphatic system to be metabolized. The heat generated in the target biological structure may induce a production of growth factors and/or fibroblasts which may improve collagen neogenesis and/or new vein formation to support the newly generated collagen formations.
Optimal wavelength should include low absorption within the skin, i.e. low absorption of water and/or melanin, and high absorption within the adipose cells. The optical waves may be in visible or in IR spectrum such as near-IR spectrum, e.g. in the range of 600 to 1500 nm in a plurality of applicable bands e.g. in the range of 635 to 680 nm, particularly 658 nm; or in the range of 780 to 980 nm, particularly 800 nm or 940 nm; or in the range of 1050 to 1100 nm, particularly 1060 nm due to relatively high penetration through the skin. Alternatively the optical waves may be in the range of 1300 to 1450 nm, particularly 1320 and 1440 nm may be applicable.
The optical treatment may last up to 120 minutes, preferably in the range of 1 to 60 minutes, more preferably in the range of 20 to 40 minutes. The treatment time may be dependent on BMI of the patient. The power flux density of the optical treatment may be up to 50 W/cm2, preferably up to 25 W/cm2, more preferably in the range of 1 to 15 W/cm2, most preferably in the range of 2 to 10 W/cm2 such as at least 5 W/cm2. In the preferred application power modulation may be used.
Optionally, active cooling may be included. However, in many cases, auto thermoregulation by sweating is sufficient. The active cooling may be administered in continual mode or in pulsed mode to maintain the skin temperature within physiologic temperature, i.e. around or below 37° C.
Alternatively, optical treatment by high power optical waves generating device may be used for treatment of incontinence or menorrhagia. One exemplary application may be inserting the optical wave generating device into the body cavity, e.g. a vagina, and treating the target biological structure by selectively heating. A suitable probe may be used for inserting the optical waves generating device. The target biological structure may be tightened due to increased temperature and/or improved collagenesis. Alternatively the optical wave generating device may be external to the body cavity and the optical waves may be delivered to target tissue by optical delivery element.
An exemplary application of application combined treatment by optical waves and magnetic treatment may be application to enhancing appearance of genitalia, e.g. external female genitalia such as labia minora, labia majora and/or clitoris. Furthermore collagenesis may be improved in vagina hence it may be smoother and/or firmer. Therefore the combined treatment may enhance physical pleasure during coitus.
Optimal wavelength of the optical waves may be in the range of 400 to 600 nm, particularly around 500 nm. Energy density may be up to 25 J/cm2, more preferably up to 10 J/cm2, most preferably in the range of 1 to 8 J/cm2. Treatment may be administered in continual or preferably in pulsed mode.
Alternatively, the application of optical waves may provide disinfection effect. Such application may include application of UV light, e.g. UV-B and/or UV-C light. The wavelength of the optical waves may be in the range of 200 to 300 nm, most preferably in the range of 250 to 270 nm. The optical radiation may destroy the DNA of microorganisms such as bacteria, or virus. The nucleic acid in DNA may form a covalent bond (such as thymine dimer) preventing unzipping process during reproduction cycle. Hence the replication ability of the microorganism is disabled and the microorganism may die and the infection may be treated. The power density may be up to 300 mW/cm2, preferably up to 200 mW/cm2, or in the range of 1 to 50 mW/cm2, more preferably in the range of 5 to 25 mW/cm2 In one exemplary application the UV light may be in external flow-chamber to provide disinfected air to the treated area.
Similar application of optical waves may be used for cleaning the skin of the patient.
The treatment by a combination of magnetic field and optical waves significantly improves the treatment effect. Most preferably, the optical waves include wavelengths ranging from 405 to 1500 nm. At least one optical waves generating device and at least one magnetic field generating device may be used.
The methods described are more gentle and efficient in adipose cells treatment or skin tightening since the target biological structure is treated by magnetic and/or by electromagnetic field.
The application of magnetic and optical treatment may be used for treatment of pelvic floor area disorders, e.g. gynaecologic and/or urologic issues such as incontinence. The magnetic treatment may be targeted to the area of pelvic floor to treat pelvic floor muscles. The repetition rate of the magnetic pulses may be in the range of 1 to 150 Hz, preferably up to 100 Hz, more preferably in the range of 5 to 70 Hz, e.g. at least 30 Hz. The optical treatment may selectively raise a temperature in the vagina to provide tightening effect. Alternatively the optical treatment may provide biostimulation effect to promote neocollagenesis. The tightening effect may be also promoted by at least partial muscle contraction. Hence the treatment of incontinence may be provided by different energy types. The collagenesis may be improved by application of magnetic treatment improving local metabolism by improved blood flow and/or at least partial muscle contraction.
Another application of magnetic and optical treatment may be used for treating a pain. The pain relieving effect may be combined and significantly improved due to different applied energies and different approaches of relieving the pain. The pain relief is drug-free and may last up to several hours after the treatment. The pain relieving may be applied for treatment of chronic and/or acute pain. Alternatively, the pain relieving effect caused by magnetic and/or optical treatment may be used for improving acceptability of optical treatment provided by high power density optical radiation, e.g. high power laser or IPL.
Still another application of magnetic and optical treatment may be used for causing relaxing effect. High efficient relaxation may be caused by combined influence optical and magnetic treatment on the biological structure.
Still another application of magnetic and optical treatment may be used for treating the adipose cells. The adipose cells may be heated by the optical treatment above 37.5° C., more preferably above 40° C., most preferably in the range of 40 and 50° C., or up to 60° C. The temperature increase may induce apoptosis and/or necrosis of the adipose cells. The apoptosis of the adipose cells may be preferred effect due to reduced risk of inflammation and/or panniculitis occurrence. The temperature increase may also liquefy the adipose tissue. The magnetic treatment may contribute the optical treatment by inducing the at least partial muscle contraction which may improve the local blood and/or lymph circulation and/or local metabolism. Hence the death adipose cells may be removed faster from the human body. The apoptosis of the adipose cells may be also contributed by the influence of the magnetic treatment to metabolism of Ca ions as was described before. The optical waves may be in visible or in IR spectrum such as near-IR spectrum, e.g. in the range of 600 to 1500 nm in a plurality of applicable bands e.g. in the range of 635 to 680 nm, particularly 658 nm; or in the range of 780 to 980 nm, particularly 800 nm or 940 nm; or in the range of 1050 to 1100 nm, particularly 1060 nm due to relatively high penetration through the skin. Alternatively the optical waves may be in the range of 1300 to 1450 nm, particularly 1320 and 1440 nm may be applicable.
The optical treatment may last up to 120 minutes, preferably in the range of 1 to 60 minutes, more preferably in the range of 20 to 40 minutes. The treatment time may be dependent on BMI of the patient. The power flux density of the optical treatment may be up to 50 W/cm2, preferably up to 25 W/cm2, more preferably in the range of 1 to 15 W/cm2, most preferably in the range of 2 to 10 W/cm2 such as at least 5 W/cm2. In the preferred application power modulation may be used.
Still another application of magnetic and optical treatment may be used for treating the cellulite. As was mentioned above the adipose cells may be influenced by apoptosis and/or necrosis. Alternatively the adipose cells may be liquefied. The adipose cells metabolism may be contributed by the at least partial muscle contraction. Furthermore the application of optical treatment may heat the fibrous septae of the cellulite. The heated septae may be straightened by the at least partial muscle contraction caused by the magnetic treatment. Further the at least partial muscle contraction may remove the water from the cellulite tissue to reduce the cellulite. Therefore more significant results may be achieved in shorter time periods. The above mentioned methods may be combined hence the enhanced effect may be induced. Hence the results may be achieved in shorted time period and may be more significant.
Still another application of magnetic and optical treatment may be used for enhancing body shape and/or improving muscle tonus to enhance visual appearance of the body part. According to one application, the muscle may be treated by the optical treatment to increase the temperature of the muscle. Afterwards the heated muscle may be treated by magnetic treatment. The magnetic treatment may achieve more significant results due to increased temperature of the muscle. The muscle may be toned and/or strengthened more effectively. The toned and/or strengthened muscle may induce body shaping effect to enhance visual appearance of the treated body part. Moreover the results may be achieved without hours spent by exercising of the muscle which may achieve unpredictable results within different body parts. The effectiveness of the magnetic treatment may be enhanced by preheating of the muscle by optical treatment. Magnetic treatment may be provided at repetition rate of at least 0.1 Hz, more preferably at least 5 Hz, even more preferably at least 20 Hz, most preferably at least 50 Hz, or up to 700 Hz. The magnetic treatment may be preferably modulated.
Still another application of magnetic and optical treatment may be used for focused treating of specific muscle structures, e.g. buttocks. The demand for enhancing visual appearance of the buttocks has rapidly increased during last few years. The combined treatment may enhance the visual appearance of the buttocks by thermal effect caused by optical treatment and/or by muscle exercising effect by focus magnetic treatment. The magnetic treatment may be selectively focus to enhancing the visual appearance of the buttocks by shredding and/or toning of the buttock muscles such as gluteus maximus, medius and/or minimus.
Alternatively, the combined focused treatment may be used for causing breast lifting effect by preheating effect of the Cooper's ligament and following magnetic treatment with increased effectiveness. The treatment may lift the breasts up.
Still another application of magnetic and optical treatment may be used for skin rejuvenation. The optical treatment may be applied to cause micro-damages within the skin to promote the increase production and/or regeneration of collagen fibers. It may induce the enhanced visual appearance of the skin which may look well-toned, smoother and/or firmer. The optical treatment may be contributed by magnetic treatment causing at least partial muscle contraction which may induce the increase local metabolism and/or blood circulation. Hence the sufficiency of nutrients may be delivered to the target biological structure to promote its regeneration and/or production process.
Still another application of magnetic and optical treatment may be used for treating the wrinkles. The optical treatment may remove the wrinkles by resurfacing of the skin. Different wavelength may promote the growth of collagen and/or elastin fibers to provide the skin younger, firmer and/or smoother appearance. The optical treatment may be contributed by magnetic treatment causing at least partial muscle contraction which may induce the increase local metabolism and/or blood circulation. Hence the sufficiency of nutrients may be delivered to the target biological structure to promote its regeneration and/or production process.
The optical treatment may provide to the target biological structure the optical waves of wavelength in the range of 500 to 3000 nm, several wavelengths may be applicable for the treatment of wrinkles e.g. 590, 640, 695, 800, 1320 or 2940 nm. Alternatively other wavelengths may be also used. The energy delivered to the target biological structure may be up to 50 J/cm2, more preferably up to 25 J/cm2, most preferably in the range of 1 to 15 J/cm2.
Still another application of magnetic and optical treatment may be used for treating the scars and/or stretchmarks. The optical treatment may enhance the visual appearance of scars and/or stretchmarks by providing improved the growth of collagen and/or elastin fibers to provide the skin younger, firmer and/or smoother appearance. The optical treatment may induce micro-damages to collagen and/or elastin fibers to promote their regeneration and/or production. The optical treatment may be contributed by magnetic treatment causing at least partial muscle contraction which may induce the increase local metabolism and/or blood circulation. Hence the sufficiency of nutrients may be delivered to the target biological structure to promote its regeneration and/or production process. Furthermore the at least partial muscle contraction may straighten the newly produced collagen and/or elastin fibers by massaging effect.
Still another application of magnetic and optical treatment may be used for lip visual appearance enhancing effect. The optical treatment may improve the growth of collagen and/or elastin fibers to provide younger, fuller, firmer and/or smoother appearance. The optical treatment may be contributed by magnetic treatment causing at least partial muscle contraction which may induce the increase local metabolism and/or blood circulation. Hence the sufficiency of nutrients may be delivered to the target biological structure to promote its regeneration and/or production process.
The above mentioned methods may be combined hence the enhanced effect may be induced. Hence the results may be achieved in shorted time period and may be more significant.
Optical treatment may be applied before the magnetic treatment. The effect of the optical treatment may be stimulating, e.g. increasing the temperature of the target biological structure to prepare a target biological structure to be treated by magnetic treatment inducing at least partial muscle contraction. To enhance the efficiency of the treatment in some indications, it may be advantageous to preheat the tissue by infrared radiation prior to magnetic treatment or combined magnetic and optical treatment.
Alternatively the effect caused by optical treatment may increase the temperature of the target biological structure, e.g. adipose cell or fibrous septae. It may be contributed by magnetic treatment causing at least partial muscle contraction. The at least partial muscle contraction may provide a massage effect for biological structures within proximity of the target biological structure, improve the blood and/or lymph circulation to improve local metabolism. Additionally the at least partial muscle contraction may reduce the number and/or volume of the adipose cells by energy used for the at least partial muscle contraction itself. Moreover, homogenous temperature distribution may be provided due to improved blood flow. Alternatively the at least partial muscle contraction may provide massage effect for promoting movement of fibrous septae.
Simultaneous application of combined magnetic and optical treatment may reach more significant results than separate use of these treatments.
Simultaneous application of magnetic treatment and optical treatment may be administered in two modes: a first mode may generate the magnetic pulses while optical treatment is active or second mode may generate magnetic pulses while the optical treatment is not in an active stimulation period, i.e. the period of magnetic treatment and optical treatment alternates.
The simultaneous application of magnetic treatment and optical treatment to the target biological structure may increase the peak magnetic component of the entire treatment resulting in improved heating of the target biological structure containing higher water volume, e.g. skin. Alternatively, the level of polarization of the optical radiation may be increased due to magnetic field, or a plane of polarization may rotate, e.g. Faraday's effect may occur. Due to increased temperature of skin, the production and/or remodeling of collagen and/or elastin fibers may be improved and the skin may be provided with a younger, smoother and enhanced appearance. The effect of overheating the muscle is reduced by the improved blood flow.
Optical treatment may also be used to attenuate the pain. Alternatively the repetition rate of the magnetic treatment may attenuate pain as well.
Optical treatment may be applied after the magnetic treatment to provide contributing effect such as analgesic effect or it may further improve local metabolism. The magnetic treatment may induce at least partial muscle contraction or to stimulate a muscle structure to increase a muscular tonus of the target biological structure. Both effects may provide a massage effect for biological structures within the proximity of the target biological structure hence the blood and/or lymph circulation may be improved to promote local metabolism. The temperature may be locally increased by the improved blood flow and the target biological structure may accept the following optical treatment at significantly higher efficiency. Hence the muscle may be heated at higher quality. Additionally, the collagen and/or elastin fibers may be remodeled or restored and/or its neogenesis may be improved to provide a younger, smoother and enhanced skin appearance.
Additionally, previous application of magnetic treatment may improve acceptability of the optical treatment. The magnetic treatment may provide pain relieving effect for the biological structure hence the thermic effect caused by the optical treatment may be more tolerable for the patient.
Another benefit may be releasing the adipose cells from the muscle by at least partial muscle contraction and/or by temperature increase causing improved metabolism of adipose cells. Still another benefit of the at least partial muscle contraction may be mechanic breaking large adipose cells bulks into smaller bulks which may be easier removed by the lymphatic and/or blood flow. The liquidity of the smaller adipose bulks may be contributed by application of optical treatment. Due to improved liquidity, improved metabolism and/or blood circulation the cellulite may be treated in a short time and the visual effect on skin appearance may be significantly enhanced.
Optical radiation may be also used to attenuate the pain after the magnetic treatment.
Combined treatments may be applied to one target biological structure to provide combined effect of magnetic and optical treatment. Alternatively the treatment may be applied to different target biological structures, e.g. optical treatment may be applied to at least adipose cell and magnetic treatment may be applied to at least one muscle fiber to improve local and/or adipose cell metabolism.
All applications of combined magnetic and optical treatment may amplify the resulting effect of the treatment. Therefore the results are achieved in significantly shorter time than the same results achieved by separate applications of the optical and magnet treatments. The treatment may be provided in various predefined treatment protocols focused on specific patient's needs, e.g. cellulite treatment, incontinence treatment, pain relieving etc. Each treatment parameter may be adjusted in the treatment protocol by the operator following the patient's needs. Alternatively the specific treatment may be designed by the operator for providing the most effective treatment following the patient's needs.
In still another application the combined treatment including magnetic treatment and mechanical treatment such as acoustic wave, ultrasound wave, shock wave treatment or massage treatment may be used for treatment of muscle issues. The mechanical treatment may be provided to the patient prior, during and/or after magnetic treatment.
Mechanical treatment refers to treatment by mechanical waves and/or acoustic waves and/or shock waves.
Mechanical treatment may be provided prior application of magnetic treatment. The mechanical treatment may induce microdamages in the target biological structure, e.g. a soft tissue such as a muscle. The microdamage may initiate and/or contribute a regeneration process of the target biological structure. The magnetic treatment may be applied consequently to improve blood flow within proximity of the target biological structure, local metabolism and/or to reduce lactate within the muscle. The magnetic treatment may provide relaxation effect.
Alternatively the mechanical treatment may be applied simultaneously with magnetic treatment. In an exemplary application the magnetic treatment may be applied to proximal part of the muscle to provide relaxation and/or pain relieving effect. The mechanical treatment may be applied to the distal part of the muscle. Such combined method may be applied for treatment of e.g. tendinopathy or tensor muscle tensor fascia latae pain syndrome.
Alternatively the mechanical treatment may be applied after magnetic treatment. The effects may be similar to simultaneous application of mechanical and magnetic treatment. In an exemplary application the combined mechanical treatment and magnetic treatment may be used for treatment of erectile dysfunctions. The mechanical treatment, e.g. a shock wave treatment, may be used for treatment of the erectile dysfunction. Afterwards the magnetic treatment may be provided to improve a blood flow within the pelvic floor, promote a sufficient amount of nutrients for the treated tissue, improve local metabolism and/or regeneration. The magnetic treatment may be applied by hand-held applicator and/or by applicator within the patient support.
