Abstract
A method and device for incising tissue within the gastrointestinal tract is described. The device is an electrosurgical sphincterotome cutting device. The sphinctertome includes a pre-curved, heat set FEP distal tip. An electrically conductive cutting wire is positioned along the pre-curved distal tip. Manipulating a control handle tightens the cutting wire and incises and cauterizes target tissue. The curvature of the distal tip allows the sphincterotome to orient and steer itself towards a patient's sphincter as it emerges from an accessory channel of an endoscope.
