Study Objectives The objective of protocol CP-0004 is to study the safety and effectiveness of the Endologix Fenestrated System in the endovascular treatment of patients with juxtarenal and/or pararenal aortic aneurysms.~Study Design This clinical study is a prospective, non-randomized, multicenter study. The first patient enrolled at each site is designated as a 'Roll-In' group patient. Subsequently, enrolled patients are designated as 'Trial' group patients for primary endpoint analysis.~Primary Endpoint The primary safety endpoint is defined as the incidence of Major Adverse Events‡ (MAEs) within 30 days. The primary study effectiveness endpoint is Treatment Success at 1-year. This is defined as procedural technical success and the absence of aneurysm rupture; conversion to open surgical repair; Type I endoleak after 30 days; Type III endoleak; clinically significant migration; aneurysm enlargement; or secondary intervention for resolution of endoleak, limb occlusion, migration, aneurysm sac expansion and/or a device defect.
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.
