1. A tubular intraluminal graft comprising:
- a) a tubular diametrically adjustable stent having an exterior surface, a luminal surface and a wall and having a multiplicity of openings through the wall of the stent;
b) a tubular covering of porous expanded polytetrafluoroethylene affixed to the luminal surface of the tubular, diametrically adjustable stent, said tubular covering being less than about 0.10 mm thick and said tubular covering having an exterior surface, a luminal surface and a seam extending from the exterior surface, through the luminal surface of the tubular covering; and
wherein said intraluminal graft is adapted for implantation in a body conduit.

Abstract
A tubular intraluminal graft in the form of a tubular diametrically adjustable stent having a tubular covering of porous expanded polytetrafluoroethylene which is less than 0.10 mm thick. The covering may be on the exterior surface of the stent, or on the interior surface of the stent, or both. The covering may be affixed to the stent by an adhesive which is preferably fluorinated ethylene propylene.
