    摘要： A novel cuspotome comprised of a long, slender arm having a substantially transverse hook section which terminates at a rounded bulbous end is presented. A sharp knife edge, which faces inwardly of the hook section is adjacent to the bulbous end. With the exception of the lower inner arm of the knife edge and inner part of the bulbous end, the entire cuspotome is coated with an electrically insulative material, preferably a fluoropolymeric material. In accordance with the technique of the present invention, after insertion into a vein and positioned adjacent a venous valve, the novel cuspotome is provided with very short, pulsed exposures of adequate wattage to instantaneously divide the cusp. The present invention is particularly well suited for removing valves of the autograft or allograft saphenous vein for bypass of arterial obliterative disease.

    摘要翻译： 提出了一种由具有基本上横向的钩部分的长而细长的臂组成的小型切割器，其终止于圆形球形端。 面向钩部的内侧的锋利的刀刃与球根端相邻。 除了刀刃的下内臂和球杆端的内部之外，整个切割器涂有电绝缘材料，优选为含氟聚合材料。 根据本发明的技术，在插入静脉中并且定位在静脉瓣附近之后，新的起子手被提供具有足够功率的非常短的脉冲曝光以瞬时分割尖瓣。 本发明特别适用于去除自体移植物或同种异体移植隐静脉的瓣膜以用于旁路动脉闭塞性疾病。
