Patent ID: 8728148

Claim:
An endoluminal prosthesis comprising: a tubular body of a biocompatible graft material having a proximal end, a distal end, an anterior side, and a posterior side, at least a first fenestration and a second fenestration in the graft material, the first and second fenestrations being spaced from one another circumferentially around the tubular body, at least one first diameter reducing tie positioned circumferentially on the posterior side of the prosthesis and directly between the first and second fenestrations and engaging at least a circumferential segment of the posterior side of the tubular body, the engaged segment of the posterior side being restrained from expansion by the first diameter reducing tie, and at least one second diameter reducing tie positioned circumferentially and directly between the first and second fenestrations on the anterior side of the prosthesis opposite the at least one first diameter reducing tie and engaging at least a circumferential segment of the anterior side of the tubular body, the engaged segment of the anterior side being restrained from expansion by the second diameter reducing tie, wherein at least a portion of the prosthesis is movable between a reduced diameter configuration and an expanded configuration, and circumferential angular position of the first fenestration in the expanded configuration is substantially the same as the circumferential angular position of the first fenestration in the reduced diameter configuration, and a circumferential angular position of the second fenestration in the expanded configuration is the same as the circumferential angular position of the second fenestration in the reduced diameter configuration.
