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.
Claims48
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 first tubular covering of porous expanded polytetrafluoroethylene affixed to the exterior surface of the tubular, diametrically adjustable stent and having an exterior surface, a luminal surface and a seam extending from the exterior surface through to the luminal surface;
- and
- c) a second tubular covering of porous expanded polytetrafluoroethylene affixed to the luminal surface of the tubular, diametrically adjustable stent, and having an exterior surface, a luminal surface and a seam extending from the exterior surface through to the luminal surface;
- wherein the combined thickness of the first and second tubular coverings is less than about 0.10 mm,thick exclusive of the stent.
A method of making a tubular intraluminal graft comprising:
- a) selecting at least one 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) affixing a first tubular covering to the exterior surface and a second tubular covering to the luminal surface, said first and second tubular coverings being in combination less than about 0.10 mm thick and said first and second tubular coverings having an exterior surface, a luminal surface and a seam extending from the exterior surface through to the luminal surface of the tubular covering.
A tubular intraluminal graft comprising:
- a) a tubular, diametrically adjustable stent having an exterior surface, a luminal surface, an end edge 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 tubular, diametrically adjustable stent;
- wherein the tubular covering of porous expanded polytetrafluoroethylene is folded over the end edge of the tubular, diametrically adjustable stent and is affixed to the exterior surface and the luminal surface of the tubular diametrically adjustable stent, and wherein the folded tubular covering has a thickness less than about 0.10 mm thick exclusive of the stent.
