Clinical Research Studies

The purpose of this study is to evaluate the use of an investigational device called the ValiantTM Visceral Manifold Thoracoabdominal Stent Graft System for the repair of thoracoabdominal aortic aneurysms (TAAA), which is a balloon-like bulge in the aorta (major artery leading away from your heart) that originates in your chest and extends to your abdomen and also includes the branch arteries that supply blood to the liver, spleen, intestine, kidneys and other organs in your abdomen. The word investigational means the device is still being tested and is not approved by the Food and Drug Administration (FDA) for sale in the United States. The Visceral Manifold System is comprised of the Thoracic Bifurcation and Visceral Manifold to treat a thoracoabdominal aortic aneurysm or TAAA. Your aneurysm may or may not have a dissection.
