Abstract

A vascular closure device comprised of a sheath-delivered cincture or noose-like device or knot comprised of suture, wire, or other suitable materials, that is placed on the external surface of a puncture wound, and closed. The vascular closure cincture is delivered by a sheath, and after closing is left resident on the external surface of a tissue puncture wound.
