Abstract
Abstract A generally tubular intraluminal vascular graft having a linear shape that may be radially expanded from a compressed state to an expanded state within a body vessel is disclosed. The graft includes a plurality of stent portions which take the form of undulating filaments extending circumferentially along the tubular body and forming a generally ring-shaped configuration. The graft may further be equipped with a plurality of specifically-configured engagement members disposed on the outer surface of the graft which are configured to frictionally engage an inner wall of a vessel so as to inhibit longitudinal movement of the tubular body without piercing the vessel wall.
