Patent ID: 8535310

Claim:
A medical sphincterotome device for directing an elongate member, comprising: an elongate member; a tubular member having a proximal portion, a distal portion, and a longitudinal axis extending therebetween; a cutting wire comprising a conductor and a cutting edge, the conductor and the cutting edge each comprising a single wire, the conductor disposed within a cutting wire lumen extending along the longitudinal axis from the proximal portion to the distal portion of the tubular member, wherein the cutting wire lumen having a cutting wire lumen distal port disposed in a side wall of the distal portion of the tubular member, the conductor extending from the proximal portion to the cutting edge, the cutting edge being exposed along the distal portion, the cutting edge being oriented generally longitudinally relative to the longitudinal axis and extending radially outward relative to the longitudinal axis; a wire guide lumen extending along the longitudinal axis from the proximal portion to the distal portion of the tubular member, the wire guide lumen having a distal port disposed in a side wall of the distal portion of the tubular member, the distal port being spaced proximally of a distal end of the tubular member, and the distal port positioned circumferentially offset and opposite from the cutting wire lumen distal port; and a non-movable deflection member operably connected to the tubular member, the non-movable deflection member disposed within the wire guide lumen and adjacent to the distal port, wherein the non-movable deflection member comprises a convex surface that is configured to engage and direct the elongate member out through the distal port at an angle away from the longitudinal axis of the tubular member, and wherein the wire guide lumen terminates at a rearward portion of the non-movable deflection member.
