Functional description

This device is part of a modular system typically consisting of a bifurcated main body and two iliac legs. It is constructed of woven polyester fabric sewn to five self-expanding nitinol Z-stents and a continuous nitinol spiral stent with braided polyester and monofilament polypropylene suture. The graft is fully stented to provide stability and the expansile force necessary to open the lumen of the graft during deployment. Z-stents provide the necessary attachment/seal of the graft to the wall.
