Hypogastric artery bifurcation graft and method of implantation

摘要

A small bifurcated graft is described which may be placed in each hypogastric artery to maintain patency both to it and to the external iliac artery and the leg below. The purpose is to maintain flow to the hypogastric artery while stenting the whole of the aorta-iliac system with endovascular overlapping straight tube grafts. Without this bifurcated device, aorto-iliac stenting would result in colonic ischemic.
