摘要：
A bipolar sphincterotome may include an elongate tubular member, a cutting wire, and a return path. The return path may include a conductive ink portion disposed on an outer surface at a distal portion of the tubular member. The return path may also include a return wire disposed within the tubular member that is electrically coupled to the conductive ink portion. In some example embodiments, the return wire may be disposed within a lumen configured to have two or more functions, one of which being to house the return wire. Additionally, in some example embodiments, the conductive ink portion may be circumferentially disposed on the outer surface to provide visual access to a wire guide lumen. Also, for some example embodiments, the bipolar sphincterotome may include two electrically isolated return paths.
