Abstract: A method and an apparatus for delivering controlled heat independently on separate channels to perform ablation to treat benign prosthetic hypertrophy or hyperplasia (BPH). The dual channel power system provides independent control of radio frequency energy to each of two stylets protruding from a catheter into a human prostate through the urethra. The energy is independently transferred directly into the respective tissue around the stylets in such a manner as to provide respective tissue ablation without damage to surrounding tissues. Automatic shut-off of both channels occurs when any one of a number of surrounding areas to include the urethra or surrounding mass or the adjacent organs exceeds predetermined safe temperature limits. Automatic shut off of the individual channels occurs when the temperature of the tissue proximal to the respective stylet exceeds respective predetermined values. The dual channel system is microprocessor controlled and contains self-test startup and thermocouple autocalibration circuitry.

Abstract: A catheter has a handle and a guide tube enclosing an interior bore. The guide tube has a proximal end and a distal end. A friction sleeve joins the proximal end of the guide tube to the handle. The friction sleeve extends from the handle and grips a portion of the guide tube beyond the handle. The friction sleeve forms a hand grip for the user beyond the confines of the handle. It also serves to effectively transmit torque applied at the handle to the distal end of the guide tube.

Abstract: Apparatus and methods are provided for treating female urinary incontinence by applying a form of energy to tissue in the vicinity of the urethra and/or bladder outlet to change tissue compliance without substantially narrowing the urethral and/or bladder outlet lumen. The apparatus comprises an elongated shaft having a means for treating urethral tissue and an expandable member deployable distal of the means for treating. The expandable member is configured to be anchored against the bladder outlet to dispose the means for treating at a desired treatment site in the urethra using only tactile feedback. The means for treating may include a needleless RF electrode, an ultrasound transducer, or a cryogenic probe configured to be advanced through a hollow needle, each of which are designed to reduce or eliminate symptoms associated with urinary incontinence.

Abstract: An apparatus includes an expandable member. The expandable member is sized to be positionable in a sphincter. An energy delivery device is positioned on a surface of the expandable member. The energy delivery device has a configuration that provides sufficient energy delivery to create lesions in the interior of the sphincter. When the expandable member is removed from the sphincter, the sphincter returns to its closed or contracted configuration.
