Various diseases, disorders, or conditions affect a significant proportion of the population. For example, essential hypertension is a global chronic disease problem. Essential hypertension can result from various factors including obesity, diabetes, smoking, lack of exercise, sodium intake, chronic anxiety, chronic stress, and aging. All of these contributing factors can cause hardening of the arteries, increased blood pressure, or excessive work load on the heart or vessels in the brain producing a substantially increased risk for heart attacks and strokes.
The autonomous nervous system including baroreceptors in the carotid and aortic arteries when in a normal healthy condition, regulate blood pressure by activating the parasympathetic nervous system by way of the vagus nerve. The autonomic nervous system has two main arms that counter-balance each other: the sympathetic nervous system is activated by stress and danger, and increases blood pressure and heart rate; whereas, the parasympathetic nervous system is the opposite, the relaxation or healing phase which brings down blood pressure and heart rate.
When hypertension is present, the sympathetic arm is over-activated and dominant aver the parasympathetic. The realities of our advanced society provide excessive stress and stimulus, aver prolonged periods of time, causing a systematic increase in blood pressure. This is a major concern as a chronic illness with serious potential outcomes.
Medical treatments for hypertension have traditionally been oral agents that affect different parts of the vascular, autonomic, and renal systems. Many oral agents, however, result in unwanted side effects. Further, the cast of such agents may be prohibitive. Holistic treatments have used relaxation stimulus, exercise, and biofeedback to attempt to lower blood pressure with poor effect.
Various devices for treatment of hypertension are also available. One such device of the related art is described in U.S. Pat. No. 7,713,295. Such devices typically rely on application of a single-temperature contact tip to a specific application site in an attempt to bring about the desired results. Some users may find the device somewhat unwieldy, e.g., struggle to correctly locate the device for the duration of treatment.
Further, current indications in the field of treatment suggest that a range of temperatures and a variety of treatment modalities may result in increasingly—beneficial health outcomes when used alone or in combination with one another.
What is needed, then, is an easy-to-use and cost-effective device, system and method that provides the functionality necessary to enhance or improve beneficial outcomes of stimulus treatment, with few or no adverse side effects.

In some aspects, a temperature sensor mounted on the contact tip can sense the present cooling temperature of the contact tip or transmit it to a temperature controller. The temperature controller can compare present cooling temperature sensed by the temperature sensor with the temperature of the contact tip set by the user. After that, the temperature controller can output a control signal, which can be modulated in pulse width corresponding to the temperature difference between the set temperature and the present cooling temperature, to a current controller. The current controller can control the strength of electric current supplied to the thermoelectric Peltier module according to, for example, the pulse width modulated control signal inputted from the temperature controller, so that the cooling temperature of the contact tip can be maintained at the cooling temperature set by the user.

Mechanism
While under no obligation to do so, and in no way limiting the scope of the present disclosure, a present understanding of one of various underlying physiological mechanism is provided.
The sympathetic nervous system is one of three major parts of the autonomic nervous system, along with the enteric and parasympathetic systems. General action of the sympathetic nervous system can mobilize the body's nervous system “fight-or-flight” response, but is also constantly active at a basic level to maintain homeostasis.
There are “baroreceptors” pressure sensors in positions of the body, such as the aortic arch or carotid bifurcation. Stimulation on the carotid sinus can cause an immediate lowering of blood pressure and heart rate. Long term blood pressure regulation is thought to be a component of the renal renin-angiotensin balance as a hormonal effect.
Studies described herein show that daily activation of the carotid sinus appears to cause a down-regulation of the sympathetic tone and an increase in the parasympathetic tone, thereby resetting a new balance in the autonomic system, a function that is hypothalamic in origin.
Arterial blood pressure is normally regulated within a narrow range, with a mean arterial pressure typically ranging from 85 to 100 mmHg in human adults. Tight control of this pressure ensures adequate blood flow to organs throughout the body. Such control is accomplished by negative feedback systems incorporating pressure sensors (i.e., barareceptors) that sense the arterial pressure Important arterial baroreceptors are located in the carotid sinus (at the bifurcation of external and internal carotids) and in the aortic arch. These receptors respond to stretching of the arterial wall so that if arterial pressure suddenly rises, the walls of these vessels can expand, which stimulates the firing of these receptors. If arterial blood pressure suddenly falls, decreased stretch of the arterial walls can lead to a decrease in receptor firing.
The carotid sinus baroreceptors are innervated by the sinus nerve of Herring, which is a branch of the glossopharyngeal nerve (IX cranial nerve). The glossopharyngeal nerve synapses in the nucleus tractus solitarius (NTS) are located in the medulla of the brainstem. The aortic arch baroreceptors are innervated by the aortic nerve, which then combines with the vagus nerve (X cranial nerve) traveling to the NTS. The NTS modulates the activity of sympathetic and parasympathetic (vagal) neurons in the medulla, which in turn regulate the autonomic control of the heart and blood vessels.
Of these two sites for arterial baroreceptors, the carotid sinus is quantitatively the most important for regulating arterial pressure. The carotid sinus receptors respond to pressures ranging from 60-180 mmHg Receptors within the aortic arch have a higher threshold pressure and are less sensitive than the carotid sinus receptors. Maximal carotid sinus sensitivity occurs near the normal mean arterial pressure; therefore, very small changes in arterial pressure around this “set point” can dramatically alter receptor firing so that autonomic control can be reset in such a way that the arterial pressure remains very near to the set point. This set point changes during exercise, hypertension, and heart failure. The changing set point can explain how arterial pressure can remain elevated during exercise or chronic hypertension.
Barareceptors are sensitive to the rate of pressure change as well as to the steady or mean pressure as well as changes in temperature. Therefore, at a given mean arterial pressure, decreasing the pulse pressure (systolic minus diastolic pressure) decreases the barareceptor firing rate. This can be important during conditions such as hemorrhagic shock in which pulse pressure as well as mean pressure decreases. The combination of reduced mean pressure and reduced pulse pressure reinforces the barareceptor reflex.
An explanation for how the baroreceptors respond to a sudden decrease in arterial pressure and how cardiovascular function is altered is as follows: A decrease in arterial pressure (mean, pulse or both) results in decreased baroreceptor firing. The “cardiovascular center” within the medulla responds by increasing sympathetic outflow and decreasing parasympathetic (vagal) outflow. Under normal physiological conditions, baroreceptor firing exerts a tonic inhibitory influence on sympathetic outflow from the medulla. Therefore, acute hypotension results in a dis-inhibition of sympathetic activity within the medulla, so that sympathetic activity increases. These autonomic changes cause vasoconstriction (increased systemic vascular resistance, SVR), tachycardia and positive inotropy. The latter two changes increase cardiac output. The increases in cardiac output and SVR lead to a partial restoration of arterial pressure.
Baroreceptors adapt to chronic changes in arterial pressure. For example, if arterial pressure suddenly falls when a person stands, the baroreceptor firing rate will decrease; however, after a period of time, the firing returns to near normal levels as the receptors adapt to the lower pressure. Therefore, the long-term regulation of arterial pressure requires activation of other mechanisms (primarily hormonal and renal) to maintain normal blood pressure.
Therapeutic Methods
Also provided is a process of treating spots on the body of a subject in need of an administration of a therapeutically effective amount of temperature stimulation, pressure stimulation, vibration stimulation, or ultrasonic stimulation via a device or system described herein, so as to treat a disease, disorder, or condition, such as hypertension.
Clinical effects of the above-described therapeutic methods of application of a cold/pressure stimulus to the carotid body sinus which upon stimulated causes a strong parasympathetic stimulus through the vagus nerve. The stimulus is in opposition to the sympathetic tone, a counterbalancing effect to decrease heart rate and blood pressure. For example, repeated daily stimulus for a predetermined time, e.g., 5 minutes, causes a continued and stronger suppression of sympathetic tone. It is postulated that this continued decreased sympathetic tone is an adjustment at the hypothalamic level and may have other medical benefits including:
In a recent (May 2011) meta-analysis that included 464,000 people, the authors showed that for a reduction of 10 mmHg systolic or 5 mmHg diastolic, there was a 22% reduction in coronary heart disease events and a 41% reduction in stroke.
Methods described herein are generally performed on a subject in need thereof. A subject in need of the therapeutic methods described herein can be a subject having, for example, been diagnosed with, suspected of having, or at risk for developing hypertension. Hypertension, or high blood pressure, is understood to be a chronic medical condition in which the blood pressure in the arteries is elevated. Blood pressure is conventionally described according to two measurements, systolic and diastolic, which depend on whether the heart muscle is contracting (systole) or relaxed between beats (diastole) and equate to a maximum and minimum pressure, respectively. Normal blood pressure at rest is within the range of about 100 to about 140 mm Hg systolic (top reading) and about 60 to about 90 mm Hg diastolic (bottom reading). A diagnosis of high blood pressure can occur, for example, where blood pressure is at or above about 140/90 mm Hg.
Generally, a safe and effective amount of temperature stimulation, pressure stimulation, vibration stimulation, or ultrasonic stimulation is, for example, that amount that would cause the desired therapeutic effect in a subject while minimizing undesired side effects. In various embodiments, an effective amount of temperature stimulation, pressure stimulation, vibration stimulation, or ultrasonic stimulation described herein can substantially reset balance in the autonomic system, decrease blood pressure, or limit the development of hypertension.
According to the methods described herein, administration can be via contact of a device or system described herein with a spot on the body of the subject. The spot on the body of the subject can be an external tissue of the subject. For example, the spot on the body of the subject can be the carotid artery baroreceptor reflex of the subject. The carotid artery baroreceptor reflex is understood to be located at the left side or right side (carotid sinus) of the subject's neck.
Contact time between a spot on the body of the subject and one or more contact tips of a device or system described herein can be about 30 seconds or more. For example, contact time can be at least about 1 minute, about 2 minutes, about 3 minutes, about 4 minutes, about 5 minutes, about 6 minutes, about 7 minutes, about 8 minutes, about 9 minutes, about 10 minutes, about 11 minutes, about 12 minutes, about 13 minutes, about 14 minutes, about 15 minutes and more. For example, contact time can be at from about 1 minute to about 15 minutes. It is understood that recitation of this range of values also refers to each separate range falling within the larger range.
Therapeutic application of temperature stimulation, pressure stimulation, vibration stimulation, or ultrasonic stimulation can be administered, at a reasonable benefit/risk ratio applicable to any medical treatment, in a sufficient amount to decrease blood pressure or limit development of hypertension.
It will be appreciated by those skilled in the art that the contact time of an individual treatment session need not in itself constitute a therapeutically effective amount, as the necessary therapeutically effective amount could be reached by administration of a number of treatment sessions.
The specific therapeutically effective amount of stimulation for any particular subject will depend upon a variety of factors including the disorder being treated and the severity of the disorder; activity of the specific stimulus employed; the age, body weight, general health, sex and diet of the subject; the time of administration; the location of administration; the duration of the treatment; drugs used in combination or coincidental with stimulus employed; and like factors well known in the medical arts (see e.g., Koda-Kimble et al. (2004) Applied Therapeutics: The Clinical Use of Drugs, Lippincott Williams & Wilkins, ISBN 0781748453; Winter (2003) Basic Clinical Pharmacokinetics, 4th ed., Lippincott Williams & Wilkins, ISBN 0781741475; Shawl (2004) Applied Biopharmaceutics & Pharmacokinetics, McGraw-Hill/Appleton & Lange, ISBN 0071375503). For example, it is well within the skill of the art to start contact time at levels lower than those required to achieve the desired therapeutic effect and to gradually increase the contact time until the desired effect is achieved. If desired, the effective contact time may be divided into multiple sessions for purposes of administration. Consequently, single sessions may contain such amounts or submultiples thereof to make up a therapeutic amount of stimulus. It will be understood, however, that the total contact time from a device of the present disclosure can be decided by an attending physician within the scope of sound medical judgment.
Again, each of the states, diseases, disorders, and conditions, described herein, as well as others, can benefit from contact time from a device or a method described herein. Generally, treating a state, disease, disorder, or condition includes preventing or delaying the appearance of clinical symptoms in a mammal that may be afflicted with or predisposed to the state, disease, disorder, or condition but does not yet experience or display clinical or subclinical symptoms thereof. Treating can also include inhibiting the state, disease, disorder, or condition, e.g., arresting or reducing the development of the disease or at least one clinical or subclinical symptom thereof. Furthermore, treating can include relieving the disease, e.g., causing regression of the state, disease, disorder, or condition or at least one of its clinical or subclinical symptoms. A benefit to a subject to be treated can be either statistically significant or at least perceptible to the subject or to a physician.
Administration of temperature stimulation, pressure stimulation, vibration stimulation, or ultrasonic stimulation via a device or system described herein can occur as a single event or over a time course of treatment. For example, temperature stimulation, pressure stimulation, vibration stimulation, or ultrasonic stimulation can be administered one or more times daily, weekly, bi-weekly, or monthly, or a combination thereof. For treatment of acute conditions, the time course of treatment will usually be at least several days. Certain conditions could extend treatment from several days, weeks, months, years, or decades. For example, treatment could extend aver one week, two weeks, or three weeks. For more chronic conditions, treatment could extend from several weeks to several months or even a year or more.
Treatment in accord with devices or methods described herein can be performed prior to, concurrent with, or after conventional treatment modalities for hypertension.
Temperature stimulation, pressure stimulation, vibration stimulation, or ultrasonic stimulation can be administered via a device or system described herein simultaneously or sequentially with another agent, such as an antibiotic, an anti-inflammatory, or another agent. For example temperature stimulation, pressure stimulation, vibration stimulation, or ultrasonic stimulation can be administered simultaneously with another agent, such as an antibiotic or an anti-inflammatory or other anti-hypertensive agents.
The following non-limiting examples are provided to further illustrate the aspects of the present disclosure. It should be appreciated by those of skill in the art that the techniques disclosed in the examples that follow represent approaches the inventors have found function well in the practice of the present disclosure, and thus can be considered to constitute examples of modes for its practice. However, those of skill in the art should, in light of the present disclosure, appreciate that many changes can be made in the specific embodiments that are disclosed and still obtain a like or similar result without departing from the spirit and scope of the present disclosure.
The following is based, at least in part, on the discovery that regular or periodic lowering of the blood pressure results in training the hypertensive subject's blood pressure to be maintained at a permanently lowered state between therapy sessions as long as a regular or periodic schedule of therapy is maintained.
A medical doctor, M.D. (Staff Cardiologist) measured BP of hypertension patient (RN/VA) prior to device treatment (130/80). Then she applied the PhysioCue device to her right side carotid sinus point for 5 minutes. Her BP was then measured immediately after treatment, and also and 30 minutes later. Her BP readings were: Initial 130/80 pre-treatment; 110/60 immediately post-treatment; 15 min post-treatment was 108/62; 30 min post-treatment was 108/70. Final BP 110/60 approximately 45 min post-treatment.
To select the HDD group and the control group, the standard (see Table 1) defined by JNC-VI (1997) and WHO/ISH (1999) was applied, and persons who had blood pressure exceeding the normal range were prescribed as hypertensive patients.
To observe a hypertension descending effect of an embodiment of the device described herein, 120 hypertensive patients were divided into an HDD group and a control group without regard to age and sex distinction. The HDD group, which used the hypertension descending device, had 60 members, and the control group, which used antihypertensive agent, also had 60 members.
The members of the HDD group and the control group were selected on the basis of patients who were in similar age and disease condition and the same sex distinction. Moreover, the patients, who participated in this experimental test, were all adults and had blood pressure exceeding normal range, which was measured three times within a predetermined period of time.
Treatment
The HDD group did not take antihypertensive agent at all during the experimental duration, and used only the hypertension descending device. The contact tip of the hypertension descending device was in contact with the patient's carotid sinus located at the left side or the right side of the human body's neck portion.
Blood pressure was measured with an automatic blood pressure measuring device (JAWON Medical Co., Ltd.).
The experimental duration was about 3 months for about 5 minutes every day, and during the above duration, blood pressure was measured before treatment, directly after the treatment, and 30 minutes after treatment.
The control group took oral antihypertensive agent according to a physician's prescription. The experimental duration was about 3 months, and blood pressure was measured once every day.
During the experimental duration, the members of the HDD group did not take antihypertensive agent at all, and used only the hypertension descending device manufactured by the JAWON Medical Co., Ud. On the other side, the members of the control group took antihypertensive agent.
Effect Criterion
A criterion of treatment effect was divided into three stages according to the descending level of systolic blood pressure, and the treatment effect was judged by percentage.
Results
The subject members for study were all 120 people, including the HDD group having 60 members and the control group having 60 members. The HDD group had 25 males and 35 females, and its average age was 58.9 (see e.g., TABLE 2).
The control group had 60 members including 28 males and 32 females, and its average age was 58.2 (see e.g., TABLE 3).
The 60 members of the HDD group were classified into 18 persons of hypertension stage 1; 37 persons of hypertension stage 2; and 5 persons of hypertension stage 3. The 60 members of the control group were classified into 18 persons of hypertension stage 1; 32 persons of hypertension stage 2; and 10 persons of hypertension stage 3 (see e.g., TABLE 4).
Treatment Effect of Hypertension Stages 1 and 2.
Results showed that in the HDD group, the hypertensive patients of hypertension stages 1 and 2 were total 55 persons, wherein 25 persons (45.5%) obtained an excellent curing effect, 23 persons (41.8%) obtained a good curing effect, and so, total 48 persons (87.3%) obtained an effective curing treatment result, but only 7 persons (12.7%) obtained a poor curing treatment result (see e.g., TABLE 5).
Meanwhile, in the control group, the hypertensive patients of hypertension stages 1 and 2 were total 50 persons, wherein 23 persons (46.0%) obtained an excellent curing treatment effect after taking oral antihypertensive agent, 21 persons (42.2%) obtained a good curing treatment effect, and so, total 44 persons (88.0%) obtained an effective curing treatment result, but only 6 persons (12.0%) obtained a poor curing treatment result (see e.g., TABLE 5).
In case of the hypertension stages 1 and 2, there was little difference between the HDD group and the control group.
Treatment Effect of Hypertension Stage 3.
There were 5 hypertensive patients of hypertension grade 3 in the HDD group, wherein the 5 hypertensive patients of hypertension stage 3 obtained little curing treatment effect by the hypertension descending device as blood pressure descending of the 5 hypertensive patients was about 10 mmHg or less.
There were 10 hypertensive patients of hypertension stage 3 in the control group, wherein 7 persons (70%) of the hypertensive patients obtained an excellent curing treatment effect after taking antihypertensive agent, and 3 persons (30%) obtained a poor curing effect (see e.g., TABLE 6).
Comparison of Treatment Effect.
48 persons (80.0%) of the total 60 hypertensive patients in the HDD group obtained an effective curing treatment result using the hypertension descending device according to the present invention, but 51 persons (85.0%) in the control group obtained the effective curing treatment result after taking hypertensive agent (see e.g., TABLE 7).
Conclusion.

As these and other variations and combinations of the features discussed above can be utilized without departing from the subject matter defined by the claims, the foregoing description of the embodiments should be taken by way of illustration rather than by way of limitation of the subject matter defined by the claims. As an example, the preceding method steps do not have to be performed in the precise order described above. Rather, various steps can be handled in a different order or simultaneously. Steps can also be omitted unless otherwise stated. In addition, the provision of the examples described herein, as well as clauses phrased as “such as,” “including” and the like, should not be interpreted as limiting the subject matter of the claims to the specific examples; rather, the examples are intended to illustrate only one of many passible embodiments. Further, the same reference numbers in different drawings can identify the same or similar elements.
