What is it? The Valiant® Thoracic Stent Graft with the Captivia Delivery System is an endovascular stent graft  and is used to repair fusiform aneurysms or saccular aneurysms/penetrating ulcers of the aorta  in the chest. The Valiant® Thoracic Stent Graft is made of a fabric tube supported by a metal framework. Each endovascular stent graft is compressed into the end of a long, thin, tube-like device called a delivery catheter.
An aneurysm  is a diseased, weakened and bulging section of an artery wall. A fusiform aneurysm is a type of thoracic aortic aneurysm that has a varying diameter and length and typically involves all sides of the diseased vessel. A saccular aneurysm is a type of aneurysm that is circular in shape and typically involves only one side of the diseased vessel. Saccular aneurysms are often associated with penetrating ulcers. A penetrating ulcer is a weak area of the aorta that causes one side of the diseased vessel to bulge or expand. Unlike a saccular aneurysm, a penetrating ulcer does not go completely through the first layer of the aorta.
How does it work? The delivery catheter containing the endovascular stent graft is inserted into an artery in the groin through a small skin cut (incision). It is carefully guided within the artery into the chest to bridge the site of the aneurysm in the aorta. The endovascular stent graft is then released (deployed) in the aorta where it self-expands to the diameter of the aorta to seal off (exclude) the aneurysm and relines the artery wall.
When is it used? The Valiant® Thoracic Stent Graft with the Captivia Delivery System is used instead of an open (more invasive) surgery in patients who have a fusiform aneurysm or saccular aneurysm/penetrating ulcer of the aorta in the chest .
What will it accomplish? The Valiant® Thoracic Stent Graft with the Captivia Delivery System should benefit patients with a fusiform aneurysm or saccular aneurysm/penetrating ulcer of the aorta in the chest by preventing further growth and rupture of the aneurysm.
When should it not be used? The Valiant® Thoracic Stent Graft with the Captivia Delivery System should NOT be used in patients who have a condition that threatens to infect the graft or in patients with sensitivities or allergies to the device materials. In addition, the device should not be used in patients who are unable to undergo the necessary preoperative and postoperative imaging  and post-implantation studies.
