1. A sphincterotome, comprising:
an elongate shaft having an outer surface and a distal end region;
a sphincterotome wire assembly coupled to the elongate shaft, the sphincterotome wire assembly including a first member and a second member;
wherein the first member includes a cutting region disposed along the outer surface of the elongate shaft and a first proximally-extending region;
wherein the second member includes a non-conductive region disposed along the outer surface of the elongate shaft and a second proximally-extending region;
a joint member disposed between and coupling the cutting region of the first member with the non-conductive region of the second member; and
wherein the sphincterotome wire assembly is designed to shift the distal end region of the elongate shaft between a first configuration and a curved configuration.
