Percutaneous Delivery of a Heparin-Impregnated Collagen Stent-Graft in a Porcine Model of Atherosclerotic Disease

Abstract

A method was developed for percutaneous implantation of collagen stent-grafts into peripheral vessels. The heparin-impregnated grafts did not prevent vessel restenosis. Modification of the graft-processing technique may improve patency.
