Abstract:
1. A variable length endovascular prosthesis adapted to prevent endoleaks, said prosthesis comprising: a substantially tubular first graft member comprising an interior surface, an exterior surface, and an open end; a substantially tubular second graft member engaged coaxially within said first graft member, the second graft member having a proximal end; and a substantially tubular fluid-tight connecting member attached at one end to said first graft member and attached at another end to said second graft member, wherein at least a portion of the connecting member is attached to the interior surface of the first graft member, with at least one end of the connecting member attached only to the interior surface, wherein said connecting member is axially compressible and expandable to facilitate engagement of said second graft member within said first graft member, such that a length of the endovascular prosthesis is variable while a particular length of the first graft member and a particular length of the second graft member is maintained, and while maintaining a seal between the proximal end of the second graft member and the open end of the first graft member and providing an opening between the first and second graft members at an opposing end of the first graft member.
