摘要： Over-the-wire self-sizing, self-centering valvulotomes sufficiently designed to cut valves through a wide range of vein diameters and adjust to the internal diameter of a vein as the valvulotome is being drawn through the vessel, and methods of use thereof during certain medical procedures that involve splitting valves, are disclosed herein. In an embodiment, an over-the-wire valvulotome includes a catheter having a proximal end, a distal end, and a longitudinal axis therebetween, wherein a first portion of a plurality of cutting tools engage the catheter at the distal end, and wherein an actuation mechanism engages the catheter at the proximal end; a retainer for temporarily shielding a second portion of the plurality of cutting tools, wherein the second portion includes cutting blades; and a sheath slidably moveable over the plurality of cutting blades, wherein the catheter and the retainer have internal diameters configured for passing over a guidewire.
