BIPOLAR SPHINCTEROTOMY UTILIZING SIDE-BY-SIDE PARALLEL WIRES ABSTRACT OF THE DISCLOSURE A bipolar sphincterotomy for use in endoscopic retrograde sphincterotomy procedures includes an elongated, flexible, plastic tube having either a single or a double lumen extending between its distal and proximal ends. At least one, but preferably two, aperture(s) is formed through the wall of the plastic tubular member a predetermined distance proximal of the distal end of the plastic tubular member. A pair of conductive wires extend through the lumen from the proximal end and exit the lumen through the aperture(s). The distal ends of pair of wires are mechanically joined to the tube so that the portions of the wires extending exteriorly of the lumen are in parallel, spaced relation with a predetermined gap therebetween. The exposed portions of the wires comprise a bipolar pair of electrodes. At least one of the wires is free to move longitudinally within the lumen of the tubular member to bow the tubular member in the location between the aperture and the points of attachment of the pair of wires to the tubular member when a pulling force is applied to one or both of the wires at the proximal end of the tubular member.
