Abstract: A urethral cap is provided for alleviating urinary incontinence when attached to the body of the user. The cap has at least a partially deformable cap body with a hand gripping portion and a body contacting encircling surface. The body defines a chamber so as to allow for a vacuum seal when applied to the body so that there is an atmospheric air pressure seal between the urethral cap and the body to prevent urinary flow beyond the urethral cap.

Abstract: A surgical instrument electrode having a tissue cutting edge disposed along a front portion and a gap having a depth extending along an axis passing through the front portion and a rear portion wherein the depth terminates in a region between the front portion and the rear portion. With such an arrangement, relatively deep gaps may be formed in the electrode without requiring a corresponding increase in the bluntness of the tissue cutting edge. In addition, the electrode has a cross-sectional shape substantially continuously changing along a portion of the electrode from a substantially circular cross-section at a distal end to a substantially rectangular cross-section along the tissue cutting edge. Due to the continuous nature of the change, undesirable electrical arcing due to the shape change is substantially reduced, and is in effect removed.

Abstract: A device for preventing male urinary incontinence is provided having a sheath and a protuberance. The sheath is sized to cover at least a portion of the glans penis of a user. The protuberance, which extends from the sheath, is sized and shaped to fit into the urethra of the user. The protuberance forms a cavity, which receives a plug. Adhesive may be disposed on the sheath to adhere it to the glans penis of the user.
