    Abstract: A method and system for treating body structures or tissue allows treatment by any of ablation, coating, expansion, plumping, shaping, and shrinking. Treatment sitesinclude any of a sphincter, sinus or orifice. During treatment, electrodes emerge from apertures in a balloon. The balloon with liquid from a circulating bath cools tissue in direct contact with electrodes and immediately adjacent, so that discrete regions are treated, with minimal damage to adjacent structures. Sensors, coupled to electrodes, measure treatment properties such as: temperature, impedance and nervous activity. Measurements are used for: diagnostic assessment, determining treatment parameters, providing nervous stimulation and/or blocking, and feedback for controlling energy delivery. The catheter includes an optical path that can be coupled to external viewing apparatus. Endoscopic methods, including fluoroscopic, fiber optic, or radioscopy allow examining tissue and determining position of electrodes. The catheter includes a suction apparatus used to remove liquids obscuring treatment area and to gently conform treatment area to electrodes.

    Abstract: An apparatus and method are provided for control contraction of tissue that includes collagen fibers. The apparatus includes a handpiece, and an electrode with an electrode proximal end associated with the handpiece. A distal end of the electrode has a geometry that delivers a controlled amount of energy to the tissue for a desired contraction of the collagen fibers. This is achieved while dissociation and breakdown of the collagen fibers is minimized. The handpiece, with electrode, is adapted to be introduced through an operating cannula in percutaneous applications. Additionally, an operating cannula may be included in the apparatus and be attached to the handpiece. The apparatus and method provides for a desired level of contraction of collagen soft tissue without dissociation or breakdown of collagen fibers.

    Abstract: This invention provides a method and system for the curative treatment of female uro-genital disorders. One aspect of the invention is that it allows the gynecologist to coagulate the entire endometrium and upper layers of the myometrium in one short procedure that can be performed in a physician's office or other outpatient setting, using local or regional anesthesia. A second aspect of the invention is that it can be used to tighten the urethral sphincter and bladder outlet.
