ABSTRACT:
The present invention is directed to an implantable vascular prosthesis configured for use in a wide range of applications, such as treating aneurysms, maintaining patency in a vessel, and providing controlled delivery of therapeutic agents to a vessel wall. The prosthesis comprises a helical body having a plurality of turns, wherein the proximal and distal edges of the turns of the prosthesis has a pattern that interdigitates when the prosthesis assumes the deployed configuration. The prosthesis optionally may comprise a radially expanding distal portion coupled to the helical body for facilitating placement of the prosthesis within a body vessel.
