In particular, the present application relates to methods and apparatuses for reducing the temporary sweat production via the temporary removal, disablement, incapacitation of apocrine and eccrine glands in the dermal and subcutaneous tissue.
[0002] BACKGROUND
[0003] Focal hyperhidrosis is an entity, in which patients sweat excessively in selected areas of the body, most commonly axillae, palms or feet. Patients sweat in general more than 30mg/min, independent of external or internal temperatures.
[0004] Focal hyperhidrosis can be followed by other diseases such as intertrigo, mycosis, bacterial infection, erythema, pigmentation, bromhidrosis, general infection or cold.
[0005] Treatment options include topical aluminum chloride or iontopheresis, which are both not very effective and are accompanied by discomfort. Same as with not so effective systemic medications, there is an injections of botulinum toxin are effective, but the effect lasts only up to six months.
[0006] Permanent options are surgical. Although effective, even the lesser invasive operations have possible surgical risks and downtime. [0007] It is known that energy-based therapies like laser therapy can be applied to tissue throughout the body to achieve numerous therapeutic and/or aesthetic results.
[0008] However, there is no effective nonsurgical, low-risk treatment of focal hyperhidrosis so far. There exists a need for the treatment of hyperhidrosis without surgical scarring or side effects of more invasive techniques. Also, patients would be most interested in a low-risk treatment, that can be done at home, although the results of such a treatment may be temporary.
Therefore, effective and improved methods, systems and apparatuses that are able to treat hyperhidrosis non-invasively with no additional risk are needed.

BRIEF DESCRIPTION OF THE FIGURES
[0013] FIG. 1 is a perspective view of an example of an apparatus for applying electromagnetic energy through the skin in order to cause a reduction of sweat glands.
DETAILED DESCRIPTION OF THIS DISCLOSURE
[0014] Disclosed herein are medical systems, novel uses and methods for the temporary treatment of sweating.
[0015] It is an idea of the present disclosure to treat sweating in a person of need with an apparatus delivering low portions of energy, in particular ultrasound or electromagenetic energy, to a sweat glands containing tissue site. In particular, the energy is less intensive than the energy applied in a typical doctor's procedure for the treatment of hyperhidrosis.
[0016] Due to applying less energy than in a hyperhidrosis treatment procedure, there are less side-effects, no local anesthesia is needed and the treatment can be performed at home, and no medical doctor is needed.
[0017] Due to the treatment with less electromagnetic or ultrasound energy, nerval pulses or glands are inhibited and/or parts of nerves, ducts or glands are denaturized. All these effects are mostly temporary. As mentioned above, the treatment is a low-risk procedure and can be done with a home-use device without supervision of a doctor or medical professional.
[0018] In an advantageous embodiment, the amount of energy transferred via ultrasound may be between 40 to 60 J/cm2, in particular between 45 to 55 J/cm2, more particular 47 J/cm2, the electromagnetic energy transferred to the area of need is between 25 and 50 J/cm2, in particular between 30 to 40 J/cm2, more particular 35 J/cm2.
[0019] The present disclosure provides methods for temporary reducing sweat glands e.g. for the temporary treatment of hyperhidrosis below a tissue surface in a selected tissue site.
[0020] The reduction or elimination of sweat glands can be done preferably transcutaneously, with a uniform reverse thermal gradient, percutaneously, transmucosally, permucosally, or through a device including but not limited to an endoscope. An electromagnetic or ultrasound energy apparatus is provided and includes an electromagnetic or ultrasound energy source and a delivery device. The delivery device is positioned on the tissue surface. Low electromagnetic or ultrasound energy is produced from the electromagnetic or ultrasound energy source and delivered through the tissue surface to the selected tissue site for a sufficient time to temporary reduce sweat glands in the selected tissue site. No burn is formed on the tissue surface. This method is particularly useful with a home-use device without supervision of a doctor or other medical professional.
[0021] However, to be able to treat hyperhidrosis effectively, it is crucial to destroy most of the sweat glands, not just a few of them. This can only be done by apllying high intensive energy e.g. via a laser or a high energy ultrasound system.
[0022] With the methods according to the present disclosure it is possible to reduce temporary a plurality of sweat glands in the selected sweat glands containing tissue site by an end-user.
[0023] Most preferably, one such low energy exposure penetrates the skin and other tissue and is absorbed by at least some sweat glands or their innervation. These sweat glands are then paralyzed or partially destroyed or the innervation is temporarily blocked. [0024] Hyperhidrosis can either be generalized or localized to specific parts of the body. Hands, feet, armpits, and the groin area are among the most active regions of perspiration due to the relatively high concentration of sweat glands; however, any part of the body may be affected. Hyperhidrosis can also be classified depending by onset, congenital or acquired. Primary hyperhidrosis is found to start during adolescence or even before and seems to be inherited as an autosomal dominant genetic trait. Primary hyperhidrosis must be distinguished from secondary hyperhidrosis, which can start at any point in life. The latter form may be due to a disorder of the thyroid or pituitary gland, diabetes mellitus, tumors, gout, menopause, certain drugs, or mercury poisoning.
[0025] Hyperhidrosis may be also divided into palmoplantar (symptomatic sweating of primarily the hands or feet), gustatory and generalized hyperhidrosis. Alternatively, hyperhidrosis may be classified according to the amount of skin that is affected and its possible causes.
[0026] The methods of the present disclosure use an electromagnetic or ultrasound energy source to apply electromagnetic or ultrasound energy to a selected tissue site. The electromagnetic or ultrasound energy can be delivered transcutaneously, with a reverse thermal gradient, percutaneously, transmucosally, permucosally, or through a device including but not limited to an endoscope.
[0027] Additionally, the methods of the present invention provide for the reduction of sweat glands underlying a tissue surface area. The overlying layer of tissue is not ablated. No deeper than a second degree burn is produced in the overlying layer of tissue, and preferably no deeper than a first degree burn.
[0028] Suitable applications for the methods of the present disclosure include but are not limited to the treatment of sweating due to hyperhidrosis, normohydrosis bromhidrosis, hidradenitis suppurativa, hypohidrotic ectodermal dysplasia, hypotrichosis, anodontia, hypohidrosis, hidrotic ectodermal dysplasia, uremic frost, neoplasms, syringomata, and various forms of miliarias. Preferably, the methods according to the present disclosure are useful for the treatment sweating due to hyperhidrosis, in particular due to Hyperhidrosis axillaris and Hyperhidrosis palmaris.
[0029] In one embodiment, an apparatus is used to create the uniform reverse thermal gradient is a composite heating pad that has both cooling elements and electromagnetic delivery devices. The heating pad is configured to the topography of the treatment area and is incorporated into an elastic garment. Partial reduction of sweat glands is achieved with each treatment. Thermal transducers measure the surface temperature of the treatment area to avoid blistering. In one embodiment the deeper dermis is heated to above 65 degrees for sweat glands destruction. Sequential treatments are designed to allow for more precision of the end result. Areas of application are not confined by requirements to either hide surgical incisions or transition along aesthetic boundaries.
[0030] The radiofrequency treatment according to the present disclosure delivers almost uniform and deep heating since only with almost uniform and deep heating it is possible to coagulate enough sweat glands to treat hyperhidrosis effectively.
[0031] A uniform reverse thermal gradient means that the energy delivery surface uniformly distributes the thermal gradient through the skin epidermis surface to the selected sweat glands containing tissue site.
[0032] Various types of electromagnetic energy can be utilized with the present disclosure. Electromagnetic energy may be any kind that can cause cell heating or physical destruction by being applied to collagen tissue.
[0033] FIG. 1 shows an example of an apparatus 10 applies electromagnetic energy through a skin layer 12, such as the epidermis, and to the underlying sweat glands tissue 14 without substantially modifying melanocytes and other epithelial cells 16 found in the lower layer of epidermis layer 12. A porous membrane 18 is adapted to receive an electrolytic solution 20. Porous membrane 18 becomes inflated to substantially conform a contacting exterior surface 22 of porous membrane 18 which is in close thermal contact with epidermis 12. Porous membrane 18 includes a cooling lumen 24 for receiving a cooling fluid that imparts a cooling effect on epidermis layer 12.
[0034] One or more electromagnetic electrodes 26 are positioned at various places in porous membrane 18. In one embodiment, electromagnetic electrodes 26 are positioned on a side that is substantially opposing to contacting exterior surface 22. In other embodiments, electromagnetic electrodes 26 are placed closer to cooling lumen 24. In embodiment particularly suitable for the hips, porous membrane is about 20 cm by 30 cm, with an oval shape. [0035] An electromagnetic power source 28 is coupled to electromagnetic electrodes 26 and a source of electrolytic solution 30 is coupled to porous membrane 18.
[0036] Various examples of an apparatus useful for the methods according to the present disclosure are described in the US patent US 6,241,753, US 6,311,090, US 6,350,276, US 6,377,855, US 6,381,497, US 6,381,498, US 6,387,380, US 6,425,912, US 6,405,090, US 6,453,202, US 7,022,121, US 7,258,674 and US 7,841,984 which are hereby incorporated by reference.
[0037] In one method of the present disclosure, sweat glands tissue in a dermis underlying the epidermis of the skin is transcutaneous contracted with the use of a thermal heating apparatus. Electromagnetic energy is transcutaneous delivered through the epidermis to the underlying dermis.
[0038] In one embodiment of the present disclosure, the method comprises the use of an ultrasound energy system - in particular, a system with a plurality of independently controlled multiple beam transducer elements that are capable of being focused at the treatment depths below the skin surface.
[0039] As mentioned above, one example for an apparatus comprising an ultrasounbd energy source is the Liposonix® device or any similar devices.
[0040] With the methods according to the present disclosure, the severity of the symptoms of focal hyperhidrosis can be temporarily reduced. For example, the severity of excessive sweating or other fluid weeping from the skin, erythematous, leathery appearance and texture, and associated pain and discomfort can be reduced.
[0041] In a preferred embodiment of the present disclosure, the methods and uses involve non-invasively treating the affected area with one of the mentioned devices, a gel sheet and a transducer, generally penetrating the skin deeply and creating a lesion in the target area.
[0042] In an embodiment, the methods and uses involves at least one or two such applications separated by two to six, and preferably four week intervals.
[0043] In another embodiment, local anesthetic cream or injection or block may be applied before the treatment. Alternatively, intravenous deep sedation or anesthesia may be used. [0044] In one embodiment of the present disclosure the Liposonix® system was used for the treatment of hyperhidrosis. The Liposonix® system is used in the prior art to apply high intense focused ultrasound to create heat and shear forces, to destroy target structures in the subcutaneous fat, adipocytes, to achieve nonsurgical body sculpting effects. The lesions induce a wound healing effect, macrophages and other cells clear up the cellular debris of disrupted adipocytes, thus leading to volume loss.
[0045] In an embodiment, the ultrasound device is used with a specific transducer and a gel sheet. In preferred embodiments, the device is used for the treatment and then waiting two to six, and most preferably four, weeks after the first treatment, and then repeating this process one or more times if necessary.
[0046] Most preferably, one such ultrasound exposure penetrates the diseased tissue and is absorbed by at least some sweat glands. These sweat glands are then disrupted and then resorbed.
[0047] The novel use of the devices leads to a treatment which is non-invasive, which can be of very significant benefit to the health care practitioner and the affected patient. The most preferred method is also believed to be very safe and easy and economical to administer without any significant complications for any patient as a result of the preferred type of treatment and procedure.
[0048] Further advantages of the high intense focused ultrasound treatment of hyperhidrosis is likely useable to treat conditions of hyperhidrosis and other conditions, that may not qualify for a diagnosis of hyperhidrosis, but exhibit similar symptoms.
[0049] In a further embodiment the present disclosure relates to the treatment of sweating due to hyperhidrosis like focal hyperhidrosis with low radiofrequenncy (RF) energy.
[0050] In embodiments according to the present disclosure apparatuses and/or systems were used for applying nonablative capacitive radiofrequency energy.
[0051] In one embodiment capacitive radiofrequency energy and surface cooling are applied by use of the Thermacool® TC3 or NXT or CPT from Solta Medical, Inc., 25881 Industrial Boulevard Hayward, CA 94545, USA or any similar devices. [0052] In a preferred embodiment the radiofrequency energy device is used with an electrode comprising specific treatment tips. The specific treatment tips can be internally and/or externally cooled.

TC3 or NXT or CPT was used in the treatment.
[0054] In one embodiment, the uses and/or the methods comprises radiation exposure involving treating the diseased tissues with a capacitive, nonablative radiofrequency device such as Thermacool TC3 or NXT or CPT with a specific treatment tip with surface cooling.
[0055] In an preferred embodiment, after the first treatment and before the next treatment it is preferred to wait two to six, and most preferably four, weeks, and then repeating this process at one or more times if necessary.
In one embodiment, local anesthetic cream or injection or block may be applied before the treatment. Alternatively, intravenous deep sedation or anesthesia may be used.
[0056] Most preferably, one such radiofrequency exposure penetrates the diseased tissue and is absorbed by at least some sweat glands. These sweat glands are then heated and destroyed.
[0057] "Standard thermal gradient" is the thermal content of tissue that is greater on the skin surface.
[0058] "Reverse thermal gradient" is, (i) the application of electromagnetic energy to alter the biophysical properties of sweat glands, i.e., reduction, with minimal blistering of the tissue surface, (ii) a gradient in which the tissue surface temperature is cooler than the underlying sweat glands comprising tissue, (iii) conditions in which a standard thermal gradient is reduced or equalized in temperature between the tissue surface and the underlying sweat glands, or (iv) monitoring the heat content (temperature and exposure duration) of the tissue surface to avoid blistering during treatment, regardless of the tissue surface temperature relative to the underlying sweat glands tissue.
[0059] "Transcutaneously" means that the delivery device delivers electromagnetic energy directly through the tissue surface. [0060] "Sweat glands" are small tubular structures of the skin that produce sweat including eccrine sweat glands which can be distributed all over the body although their density varies from region to region and apocrine sweat glands. In advantageous embodiments, the eccrine sweat glands are reduced by the methods according to the present disclosure.
[0061] "Low energy" according to the present disclosure means in advantageous embodiments energy levels delivered to the skin surface below 100 J/cm2.
