Abstract
Abstract A polypectomy device and method which includes a snare cable, a fixed jaw and a moveable jaw. The snare cable is routed through both the fixed jaw and the moveable jaw. The snare cable forms a hoop for encircling the polyp. Shortening the snare cable positions the jaws about the base of the polyp and further shortening the cable closes the jaws. The fixed jaw includes a heating element which cauterizes the base of the polyp. The closing of the jaws and the heating of the heating element cuts and seals the polyp.
