Repair of Thoracoabdominal Aortic Aneurysms

The Medtronic Valiant Thoracoabdominal Stent Graft System is made up of two main body components and makes use of several off-the-shelf FDA-approved stent graft components The system is comprised of two investigational devices that include the thoracic bifurcation and the visceral manifold. The thoracic bifurcation is deployed in the thoracic aorta and provides the proximal seal for the device. The two limbs of the thoracic bifurcation allows for continued aortic flow while deploying the visceral segment. The visceral manifold is deployed within the larger 20 mm limb of the thoracic bifurcation to set the stage for the visceral debranching. The branches of the visceral manifold extend to the visceral vessel with the use of covered bridging stents and provide distal seal of the manifold.
