摘要：
A sphincter tissue region is treated using a support structure sized for advancement into the anal canal. At least one electrode is carried by the structure. A mechanism is coupled to the electrode to move the electrode between a first position retracted in the support structure and a second position extended from the support structure 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 to conduct energy for application by the electrode to form a lesion in the subsurface tissue region.
