Claims24
An aneurysm liner, comprising:
- a liner sac disposable within an aneurysm and having an expandable body having an outer surface which faces the wall of an aneurysm when in place within the aneurysm and an inner surface, the body having a first portion and a second portion, said first portion having an exterior surface which forms a part of the outer surface of said body and said first portion having a first elasticity, said second portion having an exterior surface which forms a part of the outer surface of said body and said second portion having a second elasticity different from the first elasticity, wherein the first portion of the expandable body has a first yield strength and the second portion has a second yield strength.
An aneurysm liner, comprising:
- a liner sac disposable within an aneurysm and having an expandable body having an outer surface which faces the wall of an aneurysm when in place within the aneurysm and an inner surface and an internal surface, the body having a first portion and a second portion, said first portion having an exterior surface which forms a part of the outer surface of said body and said first portion expandable to a first configuration under a first internal pressure, said second portion having an exterior surface which forms a part of the outer surface of said body and said second portion being configured such that it plastically expands to a second configuration under a second, higher internal pressure, wherein the second internal pressure is insufficient to plastically deform the first portion.
