Abstract
Abstract A tubular prosthesis is implanted at a target location within a body lumen by transluminally placing and embedding an expansible prosthesis body within a sealing layer. The sealing layer occludes at least a circumferential band within an interface region between the prosthesis body and the inner wall of the body lumen, thus providing for blockage of body lumen flow past the prosthesis. The sealing layer may be introduced prior to or simultaneously with the prosthesis body. A tubular prosthesis may be implanted in blood vessels, particularly to protect aneurysms.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
94 words
In a method for implanting a tubular prosthesis in a body lumen of a type wherein the tubular prosthesis is expanded in situ so that an exterior surface of the prosthesis engages an inner wall of the body lumen over an interface region, the improvement comprising expanding the tubular prosthesis, in a sealing layer disposed in at least a portion of the interface region, the interface region having varying spacing between the prosthesis and the inner wall of the body lumen, the sealing layer conforming to the varying spacing to occlude the interface region.
Claim 2
Dependent Claim
94 words
In a method for implanting a tubular prosthesis in a body lumen of a type wherein the tubular prosthesis is expanded in situ so that an exterior surface of the prosthesis engages an inner wall of the body lumen over an interface region, the improvement comprising expanding the tubular prosthesis, in a sealing layer disposed in at least a portion of the interface region, the interface region having varying spacing between the prosthesis and the inner wall of the body lumen, the sealing layer conforming to the varying spacing to occlude the interface region.
Claim 3
Dependent Claim
40 words
