VASCULAR DEVICE FOR TREATING VENOUS VALVE INSUFFICIENCY

摘要

A vascular device for treating vein valve insufficiency including an elongated member, a first retention portion movable from a first elongated insertion position to an expanded position and a second retention portion movable from a first elongated insertion position to an expanded position. An intermediate looped portion is positioned between the first portion and the second portion. The valve is supported by the intermediate looped portion and is movable between an open position to allow blood flow therethrough and a closed position to inhibit blood flow therethrough. The intermediate looped portion is adjustable to loops of different diameters dependent on an inner diameter of the vessel wall.
