METHODS AND APPARATUS FOR REDUCING SWEAT PRODUCTION
Methods and apparatuses are provided for reducing sweat production via, for example, the removal, disablement, and incapacitation of sweat glands in the epidermis, dermis and subdermal tissue regions of a patient. In one embodiment, a method of treating a patient is provided which involves identifying a patient having a condition of excessive sweating, positioning an energy delivery device proximate to a skin tissue of the patient and delivering energy to sweat glands to halt secretion of sweat. The energy delivery device may include microwave delivery devices, RF delivery devices, and cryogenic therapy devices. Some embodiments may include using a cooling element for avoiding destruction of non-target tissue and/or a suction device to localize treatment at specific portions of the skin fold.
1 . An apparatus for treating an area of skin tissue of a patient, said apparatus comprising:
a microwave generator;
a grasping mechanism configured to grasp the area of skin tissue to form a skin fold having a first side and a second side;
a cooling element configured to apply protective cooling to at least a portion of the area of skin tissue; and
first and second microwave antennas coupled to the microwave generator and associated with the grasping mechanism such that, when the skin fold is formed, the first microwave antenna is positioned on the first side of the skin fold and the second microwave antenna is positioned on the second side of the skin fold, wherein the first and second microwave antennas are configured to deliver microwave energy through the cooling element to the area of skin tissue.
2 . The apparatus of claim 1 , wherein the cooling element adapted to be positioned proximate to the skin fold when skin tissue is positioned in the grasping mechanism.
3 . The apparatus of claim 1 , wherein the cooling element comprises a first cooling element adapted to be positioned proximate the first side of the skin fold and a second cooling element adapted to be positioned proximate to the second side of the skin fold when skin tissue is positioned in the grasping mechanism.
4 . The apparatus of claim 1 , wherein the grasping mechanism comprises a suction mechanism configured to provide suction to the skin tissue when the skin tissue is positioned in the grasping mechanism.
5 . The apparatus of claim 4 , wherein the suction mechanism is configured to provide suction to the skin tissue to position the skin tissue in the grasping mechanism.
6 . A method of treating a patient comprising:
identifying an area of skin tissue;
grasping the area of skin tissue to form a skin fold, the skin fold comprising a first side and a second side, wherein, when folded, the first side is proximally adjacent to second side such that the layers comprise a treatment zone;
applying protective cooling with a cooling element to at least a portion of the area of skin tissue; and
positioning microwave antennas on the first and second sides of the skin fold and delivering microwave energy with the microwave antennas through the cooling element to the treatment zone to yield a treatment effect, said treatment effect reducing the amount of sweating from the area of skin tissue.
7 . The method of claim 6 , wherein applying protective cooling to at least a portion of the area of skin tissue further comprises positioning the cooling element proximate the skin fold.
8 . The method of claim 7 , wherein positioning the cooling element proximate the skin fold further comprises positioning a first cooling element proximate the first side of the skin fold and a second cooling element proximate the second side of the skin fold.
9 . The method of claim 6 , wherein grasping the area of skin tissue to form the skin fold further comprises providing suction to the area of skin tissue.
10 . The method of claim 9 , wherein providing suction to the area of skin tissue further comprises maintaining suction to the area of skin tissue during the treatment.
