<p>An endoluminal prosthesis (210) is provided with an improved fixation system for coupling the endoluminal prosthesis to an inner wall of a lumen. According to an embodiment of the present invention, the functions of securing proximal fixation of of the graft and delivering the main body of the prosthesis to bypass the diseased vessels are independently carried out using a modular device and modular steps for delivery and placement of the modular components. In particular a modular fixation device is provided for initial fixation to a lumen wall and a longer endoluminal prosthesis is provided for coupling to the fixation device, and bypassing a diseased portion of the anatomy. In one embodiment, the longer endoluminal prosthesis includes hook-like members (117) that engage loops on the modular fixation device. <IMAGE></p> |
