SYSTEMS AND METHODS FOR TREATING DYSFUNCTIONS IN THE INTESTINES AND RECTUM

摘要

A sphincter tissue region is treated using a support structure (42) sized fo r advancement into the anal canal. At least one electrode (66) is carried by t he 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 surfa ce 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.
