1. A tubular wire support for a bifurcated endoluminal prosthesis, said wire support comprising:
- a main body support structure having a proximal end, a distal end and a central lumen extending along a longitudinal axis therethrough;
a first branch support structure having a proximal end, a distal end and a central lumen therethrough, wherein the distal end of the first branch support structure having a connector pivotably connected to the proximal end of the main body support structure to provide interlocking links; and
a second branch support structure having a proximal end, a distal end and a central lumen extending therethrough, wherein the distal end of the second branch support structure having a connector pivotably connected to the proximal end of the main body support structure to provide interlocking links;
wherein the main body support structure and the first and second branch support structure are self-expandable from a radially collapsed state to a radially expanded state.

Abstract
Disclosed is a tubular endoluminal vascular prosthesis, useful in treating, for example, an abdominal aortic aneurysm. The prosthesis comprises a self-expandable wire support structure having a tubular main body support and first and second branch supports. The branch supports articulate with the main body so as to permit the branches to extend laterally from the axis of the main body throughout a substantial range of motion.

10. A tubular wire support for combination with a sheath to produce a bifurcated endoluminal prosthesis, said tubular wire support comprising:
-
a main body support structure having a proximal end, a distal end and a central lumen extending therethrough;
a first branch support structure having a proximal end, a distal end and a central lumen therethrough, wherein a lateral portion of the distal end of the first branch support structure is connected by a first slideable linkage to a first portion of the proximal end of the main body support structure; and
a second branch support structure having a proximal end, a distal end and a central lumen extending therethrough, wherein a lateral portion of the distal end of the second branch support structure is connected by a second slideable linkage to a second portion of the proximal end of the main body support structure, and wherein adjacent portions of the distal ends of the first and second branch support structures are joined to each other by a flexible linkage, such that the first and second branch support structures can extend laterally outward from the longitudinal axis without compromising luminal integrity. - View Dependent Claims (11, 12, 13, 14, 15)

16. An articulating bifurcation graft, comprising:
-
a tubular main body support structure having a proximal end and a distal end;
a first branch support structure pivotably attached to the main body support structure;
a second branch support structure pivotably attached to the main body support structure; and
a tubular polymeric sleeve surrounding at least a portion of the articulating bifurcation graft;
wherein the pivotable attachment comprises a loop on a proximal portion of the main body support structure, and at least one apex from each of the first and second branch support structures extending through the loop to provide a pivotable connection therebetween. - View Dependent Claims (17, 18)
