A valvulotome for rendering venous valve leaflets incompetent includes a rigid support comprising a fluid supply tube and, molded thereon, a dilator, and first and second valve disrupting heads. Each of the disrupting heads has a plane of symmetry, wherein the planes of symmetry of the two disrupting heads are relatively rotated by about 90.degree.. A fluid emitting end of the fluid supply tube communicates with an irrigation port in a disrupting head so that fluid emitted through the irrigation port, during use, applies pressure to the valve leaflets to be disrupted. The other end of the fluid supply tube is swaged onto a catheter which in turn is coupled to a fluid supply source for the purpose of supplying fluid to the irrigation port.
