Abstract

A tubular intraluminal prosthesis includes a PTFE or ePTFE tubular structure such as a graft, and a tubular diametrically deformable stent circumferentially surrounding the tubular structure. The diametrically deformable stent includes a polymeric coating which allows for attachment to the tubular graft structure and enhances the biocompatibility and integrity of the composite prosthesis.

Claims

1. A tubular intraluminal prosthesis comprising:

an ePTFE tubular graft structure having opposed interior and exterior surfaces;

a tubular diametrically deformable stent in contact with said PTFE tubular graft structure; and

said stent being at least partially coated with a polymeric coating;

said stent being affixed to said tubular structure at said at least partial coating.
