Brief Summary:
Study of anatomical fixation with a 34mm proximal extension

Condition or disease Intervention/treatment Phase
Abdominal Aortic Aneurysm Device: Endologix Powerlink 34 mm stent graft cuff Phase 2 Phase 3

Expanded Access : Endologix has indicated that access to an investigational treatment associated with this study is available outside the clinical trial.  

Detailed Description:
The 34mm proximal extension stent graft is intended to augment the primary 28mm infrarenal bifurcated stent graft to accommodate patient anatomy (neck diameters up to 32mm) and provide an effective seal to prevent/repair proximal Type I endoleaks.
