Stent/grafts designed for percutaneous deployment into the aorta. These devices typically consist of a metallic meshlike supporting frame (e.g., a set of self-expanding stents) covered with a graft (e.g., made from a synthetic material such as Dacron). Most aortic stent/grafts are used to bypass lower abdominal (under the renal artery) aortic aneurysms. The stent/grafts are introduced within the aneurysm through the femoral arteries in the groin area. Aortic stent/grafts divert the flow of blood away from the aneurysm wall, excluding the aneurysm from circulation. The procedure does not remove the aneurysm but allows it to shrink over time.
