Safety and Effectiveness Trial of the Ventana Fenestrated Stent Graft System
Prospective, Multicenter, Single Arm Safety and Effectiveness Trial of the Endologix Fenestrated Stent Graft System for the Endovascular Repair of Juxtarenal/Pararenal (JAA/PAA) Aneurysms

The purpose of this trial is to determine if the Ventana Fenestrated Stent Graft System is safe and effective for the endovascular repair of juxtarenal or pararenal aortic aneurysms.
