Apparatus (20) 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 (20) comprises an elongated shaft (22) having a means (41-44) for treating urethral tissue and an expandable member (55) 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.

L'invention concerne un appareil et des procédés permettant de traiter l'incontinence urinaire féminine par application d'une forme d'énergie sur les tissus situés à proximité de l'orifice de l'urètre et/ou de la vessie afin de modifier la compliance des tissus sans rétrécir sensiblement la lumière de sortie de l'urètre et/ou de la vessie. L'appareil de l'invention comprend une tige allongée présentant un moyen de traitement de tissu urétral et un élément expansible pouvant se déployer à distance du moyen de traitement. Ledit élément expansible est conçu pour être fixé contre l'orifice de la vessie afin de disposer ledit moyen de traitement au niveau d'un site de traitement désiré dans l'urètre uniquement au moyen d'un retour tactile. Ledit moyen de traitement peut comprendre une électrode RF sans aiguille, un transducteur à ultrasons, ou une sonde cryogénique conçue pour être avancée par l'intermédiaire d'une aiguille creuse, chacun de ces éléments étant destiné à réduire ou à éliminer les symptômes associés à l'incontinence urinaire.
