Abstract: A bipolar sphincterotome includes: an elongate tubular member longitudinally extending from a proximal portion to a distal portion; a cutting wire longitudinally extending in the elongate tubular member, and extending to outside of the elongate tubular member via a cutting wire opening in the elongate tubular member; a return wire longitudinally extending from the proximal portion to the distal portion; and a return electrode electrically coupled to a return wire, where the return electrode includes a proximal cannula disposed proximal a cutting wire opening and a distal cannula disposed distal an anchor point, where both the proximal cannula and the distal cannula are electrically coupled to the return wire, and where both the proximal cannula and the distal cannula are metallic.

Abstract: The present disclosure relates to a physician controlled single hand operated handle system. The system includes a handle. The handle includes an actuator, a stem disposed within the actuator and longitudinally movable within the actuator, a sheath attached to the stem, and an elongate member extending through the sheath. The elongate member is longitudinally constrained by the actuator and rotatably constrained by the stem.

Abstract: A sphincterotome includes a variable thickness cover that covers an insulated portion of a cutting edge. The variable thickness cover includes a distal taper distally extending from a first outer diameter to a second outer diameter, where the first outer diameter is larger than the second outer diameter.

Abstract: A medical device includes a handle that includes a first member and a second member. Outer and inner elongate members of the medical device project from a distal end of the first member. The first and second members move, such as rotationally or pivotably move, relative to each other to control relative longitudinal movement of the outer and inner elongate members.

Abstract: Certain embodiments of the present disclosure are directed to quick release fishing assemblies providing improved performance in ease of handling and mitigation of inadvertent disengagements.
