EXTERNAL REPAIR OF INCOMPETENT VENOUS VALVES

摘要

The present invention relates to a method and device for repairing incompetent venous valves and more specifically, to a repair metho and an implantable support device- extravenous corrector, which is positionable about dilated veins of the Sapheno-Femoral Junction (SFJ) with the aim to apply an external compression force on the insufficient veins of the SFJ and especially in the area of the venous valves. The extravenous corrector comprises a central support member (11) and at least three band lengths (13, 15, 17), connected to the member (11), adapted for placement around at least two veins of the venous junction in the area of location of their insufficient valves, these band lengths (13, 15, 17) possessing different rigidity and compressing force in direction from their proximal end to the distal end.
