Abstract
A variable length endovascular prosthesis adapted to prevent endoleaks is provided that includes a substantially tubular first graft member having an interior surface, an exterior surface, and a proximal end, and a substantially tubular second graft member slidably engaged coaxially within the first graft member. The prosthesis further includes a substantially tubular fluid-tight connecting member attached at one end to the first graft member and attached at another end to the second graft member. The connecting member is axially compressible and expandable to facilitate engagement of the second graft member within the first graft member while maintaining a seal between the graft members.
Claims21
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 a proximal end;
- a substantially tubular second graft member engaged coaxially within said first graft member;
- 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 said connecting member is axially compressible and expandable to facilitate engagement of said second graft member within said first graft member while maintaining a seal between said graft members.
A method of providing a variable length tubular endovascular prosthesis, said method comprising the steps of:
- attaching a substantially tubular fluid-tight connecting member at one end to a substantially tubular first graft member comprising an interior surface, an exterior surface, and a proximal end;
- attaching the connecting member at another end to a substantially tubular second graft member engaged coaxially within the first graft member;
- said connecting member being axially compressible and expandable so as to facilitate a variable length engagement of the second graft member within the first graft member;
- and
- maintaining a seal between the graft members.
A variable length endovascular prosthesis adapted to prevent endoleaks, said prosthesis comprising:
- a substantially tubular first graft member;
- a substantially tubular second graft member engaged coaxially within said first graft member;
- and
- a means for permitting axial compression and expansion of said prosthesis to facilitate variable length engagement of said second graft member within said first graft member while maintaining a seal between said graft members.
