Claim:
A modular stent graft for repairing an aneurysm in the human aorta, the stent graft comprising: a collapsible flexible bifurcated graft having a bifurcated hip section, a first pant leg section that extends from said bifurcated hip section to a first proximal end, and a second pant leg section that extends from said bifurcated hip section to a second proximal end; at least one collapsible stent member including stent elements that surround and support the bifurcated graft, a first set of stent elements that are proximally disposed relative to and spaced apart from said first proximal end of said first pant leg section by at least one connector element, and a second set of stent elements that are proximally disposed relative to and spaced apart from said second proximal end of said second pant leg section by at least one connector element; a collapsible flexible first leg graft that interconnects to said first pant leg section of said bifurcated graft, said first leg graft having an exterior surface; a collapsible flexible second leg graft that interconnects to said second pant leg section of said bifurcated graft, said second leg graft having an exterior surface; a third set of stent elements that are disposed external to and surrounding said exterior surface of said first leg graft at a position offset proximally from the distal end of said first leg graft, wherein said third set of stent elements are operably disposed between said first proximal end of said first pant leg section and said first set of stent elements to thereby maintain interconnection between said first leg graft and said first pant leg section of said bifurcated graft; and a fourth set of stent elements that are disposed external to and surrounding said exterior surface of said second leg graft at a position offset proximally from the distal end of said second leg graft, wherein said fourth set of stent elements are operably disposed between said second proximal end of said second pant leg section and said second set of stent elements to thereby maintain interconnection between said second leg graft and said second pant leg section of said bifurcated graft.
