Patent ID: 8257430

Claim:
A modular endoluminal prosthesis comprising: a primary prosthetic module comprising a graft and at least a first proximal opening and first and second distal openings defining a bifurcation; and a secondary prosthetic module comprising a first stent graft having a first graft and at least one stent, a second stent graft having a second graft and at least one stent, and a flexible bridge having a first end attached to the first stent graft and a second end attached to the second stent graft; where at least a portion of the first stent graft is disposed within and extends through the first distal opening of the primary prosthetic module and at least a portion of the second stent graft is disposed within and extends through the second distal opening of the primary prosthetic module; and where the bridge is longitudinally flexible and expands within the primary prosthetic module from a first configuration to a second configuration, where the distance along the bridge between the first and second stent grafts is greater in the second configuration than in the first configuration so that the combined length of the first stent graft, second stent graft, and bridge, is greater in the second configuration than in the first configuration, and where the bridge spans the bifurcation.
