摘要： A cuff for restoring competence to an incompetent venous valve consists of a band of biocompatible implantable material that is not stretchable at blood flow pressures. The band is of sufficient length to encompass the vein at the site of the venous valve with the ends of the band overlapping. In one form of attachment, the end 22 passes over the loop 23 and is stapled thereto. The cuff can be attached to an applicator by means of the loop 23. A portion 26 of reduced thickness extends from the bottom face of the band to reduce any inner surface discontinuities with respect to the wall of the vein.The cuff is placed around the vein at the site of the valve and the circumference of the cuff (and hence the diameter of the vein at the valve site) is reduced until competency of the valve in the vein is restored.

摘要： An applicator for applying a strap around a vein at the site of a defective venous valve includes a handle portion and a removable cartridge. One end of the strap is anchored on the anvil of the cartridge and the free end is looped around the vein and passed through an opening in the cartridge to overlie the anchored end. The free end of the strap is connected to a strap puller within the cartridge which is coupled to a strap puller extension within the handle when the cartridge is inserted in the handle. The perimeter of the loop is adjusted by moving the tensioner on the handle. When the loop perimeter is at its desired value, the triggers on the handle are pressed to drive a staple through the overlying portion of the strap. A knife within the cartridge cuts the excess strap from the loop.
