ABSTRACT:
A valvulotome for disrupting a valve in a vein includes an elongate control member and a cutting head disposed at the distal end of the control member. The cutting head includes an elongate section extending generally along the length of the cutting head and a return section extending beside the elongate section also along the length of the cutting head. A cutting section included in the cutting head extends between the elongate section and the return section at a particular angle to the length of the control member. Portions of this cutting section form a proximally facing cutting edge for disrupting the valve. The valvulotome can be used with an endoscope in a method wherein the cutting head is tied to the endoscope with a suture, or a method wherein the valvulotome is back-loaded into the working channel of the endoscope.
