The purpose of this research study is to continue to test how well the Endospan NEXUSTM Aortic Arch Stent Graft System performs in the treatment of a diseased aortic arch. The aortic arch is the top part of the main large vessel that carries blood away from the heart. A stent graft is a self-expanding frame that is covered with a material intended to seal the vessel walls.
The NEXUS Aortic Arch Stent Graft System is delivered to the diseased area of your aorta by traveling through your vascular system using fluoroscopic guidance (x-ray pictures), starting with a small incision or needle puncture near your groin (inner thigh). The NEXUS Aortic Arch Stent Graft System is being studied and is not approved by the FDA which means it is investigational in this study. The NEXUS Aortic Arch Stent Graft System has CE Mark which means it is approved for use in Europe. The NEXUS Aortic Arch Stent Graft System is only available through the clinical study in the United States.

This study is being conduct to assess the safety and effectiveness of a Study Sevice,GORE® EXCLUDER® Conformable AAA Endoprosthesis, in patient's with an aneurysm in their abdominal aorta. In this research study, the Study Device will be placed inside the abdominal aorta (in the approximate area of the belly button) and the Study Device will extend into both leg arteries. The Study Device will block the aneurysm (the weakened and bulging part of the artery) in the abdominal aorta from blood flow while maintaining blood flow to the arteries in the legs. Information will be collected on the performance of the Study Device for up to five (5) years.
