Abstract
A sphincterotome (21), such as a papillotome, is disclosed for surgical cutting using an electrically conductive cutter wire (33). The sphincterotome (21) includes a multi-lumen tubular member (27), with one lumen (55) having an electrical conductor (43) disposed therein, and the other lumen (57) having a reinforcing wire (45) disposed therein. The reinforcing wire (45) is preferably rectangular in cross-section, providing a greater moment of inertia in a resisting axis R than in a bending axis B. Accordingly, the cutting edge (53) of the cutting wire (33) may be oriented to the 12 o'clock position of the papillary orifice to avoid injury to the duodenal wall or pancreatic duct (69) in the patient, and to maintain the cutting edge (53) in a predetermined cutting plane P. Fluoroscopic indicating stripes (39, 41) may be provided at the distal end (23) of the sphincterotome (21). A method of use and method of fabrication of the present invention is also disclosed.
