Abstract
An electrosurgical system may include a medical delivery device and an electrosurgical device to perform an electrosurgical procedure. The electrosurgical device may have a monopolar configuration. An outer surface of the medical delivery device may include a conductive portion that is part of a return path for a bipolar configuration. Current may be supplied through an active member of the electrosurgical device to perform the procedure. After passing through tissue, the current may be drawn to the electrode portion of the medical delivery device to complete the circuit.

A method comprising:
- delivering a distal portion of a medical delivery device to a treatment site within a patient for performance of a sphincterotomy, wherein the medical delivery device comprises an outer surface and a return electrode that is at least one of disposed on or integrated with the outer surface;
- contacting the return electrode of the medical delivery device to an inner wall of a duodenum of the patient when the distal portion is at the treatment site;
- delivering an electrosurgical device through a working channel of the medical delivery device to the treatment site;
- and
- cutting a papilla of the patient with an active member of the electrosurgical device while drawing electrical current through the active member of the electrosurgical device and the return electrode of the medical delivery device, and while the return electrode of the medical delivery device is contacting the inner wall of the duodenum.
