An endoluminal prosthesis comprises a tubular member having a proximal opening and a distal opening providing a lumen through which body fluids may flow. The tubular member is constructed of a graft material. The tubular graft is formed of a first material such as a woven fiber or other suitable material for conducting fluid, and sections of a second material configured to extend or contract to permit the tubular graft to flex or straighten to conform to the anatomy in which it is deployed.
