The present invention generally pertains to a system and method for treating skin conditions by applying medicament and RF treatment in conjunction with each other.
Improving the appearance of the skin has been the goal of many esthetic products and procedures for many years, since a tight skin, without wrinkles or cellulite, has a younger and more appealing appearance. Apart from age related changes, the skin also suffers from exposure to chemical and physical injuries, such as tobacco, cosmetics, esthetics and radiation from the sun and other sources. Those factors contribute to the decrease in collagen production, to reduced elasticity, and the appearance of wrinkles.
The skin and muscles of the face are structured differently than other places on the body. One side of the facial muscles is connected to the bone and the other to the skin. As the muscle deteriorates through the aging process, the attached facial skin loses it elasticity. Loss of elasticity causes the skin to sag and wrinkle. Strengthening relevant muscle groups restores and maintains the original shape and contour of the muscles. As facial muscles get stronger, they get shorter and flatter, causing the attached skin to become firmer, and smoothing wrinkles, improving facial appearance. Additionally, a contracting muscle's blood supply is 10 times greater than a muscle at rest. This fresh blood supply delivers vital oxygen and nutrients to the skin, revitalizing the tissue.
The most common method of heating the dermis, is the use of RF radiation, applied by antenna or electrodes. For example, WO98005380 discloses a method of tightening skin using an RF electromagnetic energy delivery device. However, the manner (and specifically, the protocol) in which the RF is transmitted to the region of interest is highly important. Some methods will have no effect and others may have the opposite effect.
U.S. Pat. Appl. 20100016850 discloses an invention that demonstrates that application of electrical currents of about 1 milliampere, and voltages greater than 4V have a much greater esthetic effect on the skin than application of lower currents and voltages known in the prior art. This application further discloses that simultaneous application of electrical currents on the skin yields better esthetic results.
It can be desirable to include medicaments during the treatment. Medicaments can include, but are not limited to, a local anesthetic to reduce the discomfort of the RF treatment, medicaments intended to treat the skin condition, a dye to absorb light in embodiments that use optical means for effecting deep tissue diathermy, a muscle relaxant, etc.
RF energy can improve the efficacy of transdermal delivery of medication.
Thus, means for providing RF (or in general, any kind of energy) to the region of treatment (e.g., the skin) in conjunction with transdermal delivery of medication remains a long-felt, yet unmet, need.

Therefore the invention is not limited by that which is illustrated in the figures and described in the specification, but only as indicated in the accompanying claims, with the proper scope determined only by the broadest interpretation of said claims.
With respect to parameters that characterize the invention disclosed herein and the cosmetic treatment effected thereby, “unsafe” parameters are understood to be parameters that will cause tissue damage or excessive discomfort to the person undergoing treatment, e.g. overheating, transmitting energy to tissue layers below the skin, etc. According to one embodiment, the device of the present invention automatically prevents the parameters from reaching the unsafe zone and maintains the same within the safe zone.
The invention comprises a novel device for improving the cosmetic appearance of the skin, which is described in detail below. In preferred embodiments of the invention, the cosmetic improvement achieved includes at least one of skin rejuvenation; reduction in the number of wrinkles; reduction of the depth of wrinkles; reduction of cellulite; skin tightening; circumferential reduction.
Said cosmetic improvement is achieved by applying energy to the skin. The energy is selected from a group consisting of RF, Intense pulsed light (IPL), laser and any combination thereof.
The following disclosure is provided for RF energy, however the same applies both to laser or IPL treatment.
The invention provides an integrated mechanism for improving the cosmetic appearance of the skin. In the prior art the skin is treated with RF, then the RF applicator is removed and medicament is applied to the skin. Unlike the prior art, in the present invention, any of the following can be done, all without removing the device from the skin: medicament and RF can be applied simultaneously, or medicament can be applied, then RF, or RF then medicament, or RF and medicament can be applied alternately.
Furthermore, for the user, the device provides single step application of medicament and RF. In all embodiments, the user applies the device to the skin and operates the device, whether operation involves turning it on, squeezing it, or otherwise manipulating it. The user need not concern herself with the details of operation; the medicament will automatically be dispensed and the RF automatically applied as appropriate for the embodiment. For non-limiting example, in variants of embodiments where RF and medicament are applied simultaneously, each time the user squeezes the housing, medicament is dispensed onto the skin and RF is simultaneously applied to the skin.

The predetermined pressure can be exerted by a method selected from a group consisting of: pressing the sides of the housing (120) toward each other; twisting a portion of the housing (120) relative to another portion, thereby compressing the capsule (130) between an upper anvil (which can be the top of the housing (120)) and the base of the housing (120); twisting a portion of the housing (120) relative to another portion, thereby pressing the capsule (130) against the tops of the electrodes (140), twisting a portion of the housing (120) relative to another portion, thereby pressing the capsule (130) against sharp objects in the base of the housing (120), or any combination thereof. Other methods of applying pressure to the capsule (120) will be obvious to one skilled in the art.
The electrodes (140) are adapted to deliver energy to the skin, preferably RF energy. The control means enables the energy to be applied to any subset of the electrodes, and to apply it in any desired pattern. For non-limiting example, energy can be applied to the electrodes (140) in random order, minimizing heating of the skin; or energy can be applied along a line of electrodes (140), sweeping along a wrinkle or scar while avoiding treating (or heating) unwrinkled skin. Other patterns of application will be obvious to one skilled in the art.
In some embodiments, the electrodes (140) are fixed in position.
In some embodiments, the electrodes (140) are extendible from the housing (120) such that, during storage and transport, the electrodes (140) are retracted within the housing (120) and are protected from damage.
