Device and method for external correction of insufficient valves in venous junctions

摘要

A compression device for external correction of insufficient valves in venous junctions is adapted for placement around the junction. The compression device has a band encompassing at least two veins of the junction. The band has a different rigidity and compression force in a direction extending from its proximal end to its distal end. The band is formed with a main compressing portion disposed on a vein surface of the junction around an insufficient valve. Intermediate and fastening portions of the band are also disposed on the vein surfaces adjacent the main compression compressing portion. The band is preferably shaped as a Mobius band. A method for external correction of insufficient valves in venous junctions is also disclosed.
