An endovascular stent graft is like having a small, metal scaffold inside your aorta that supports the weak area.
An endovascular stent graft is a synthetic fabric tube (graft) supported by a metal structure (stent). The stent graft helps to bypass the weakened area of your aorta.
The stent graft is designed so that it can be placed inside the damaged area of your aorta, without surgically opening the blood vessel or removing any tissue.
The Valiant Navion® Thoracic Stent Graft is used to treat descending thoracic aortic aneurysms.
