A sphincter tissue region is treated using a support structure (42) sized for advancement into the anal canal. At least one electrode (66) is carried by the structure (42). A mechanism (68) is coupled to the electrode to move the electrode (66) between a first position retracted in the support structure, and a second position extended from the support structure (42) through surface tissue to penetrate a subsurface tissue region at or near a sphincter in the anal canal. A cable is coupled to the electrode (66) to conduct energy for application by the electrode (66) to form a lesion in the subsurface tissue region.

On traite une zone tissulaire du sphincter à l'aide d'une structure de support (42) dimensionnée pour pouvoir être introduite dans le canal anal. Cette structure (42) contient au moins une électrode (66). Un mécanisme (68) est couplé à cette électrode (66) pour la faire passer d'une première position repliée dans la structure de support à une seconde position déployée de la structure de support (42) à travers un tissu en surface, pour lui permettre de pénétrer dans une zone tissulaire en sous-surface au niveau ou à proximité du sphincter dans le canal anal. Un câble est couplé à l'électrode (66) pour conduire l'énergie devant être appliquée par l'électrode (66), en vue de former une liaison dans la zone tissulaire en sous-surface.
