Fig. 2. The AneuRx modular aortic stent graft consists of a primary aorto-iliac component and a contralateral limb that fuse together to form a bifurcated endoluminal graft as shown. Each component consists of a thin-walled, noncrimped, woven polyester graft with a self-expanding nickel-titanium (nitinol) exoskeleton. Primary modules, iliac limbs, and proximal and distal extender cuffs are available in different lengths and diameters to obtain a “best fit.”
