  7. Subject has vascular dimensions in the range of sizes available for the Endurant Stent Graft
  8. Subject has documented imaging evidence of at least 1 patent iliac and 1 femoral artery, or can tolerate a vascular conduit that allows introduction of the device.

Primary Outcome Measures
NameTimeMethod
Major Adverse Events Within 30 Days of Index Procedure30 days

The primary safety endpoint is composite defined as the proportion of subjects free from major adverse events (MAE) within 1 month (day 0 - Day 30)of implant is non-inferior to the proportion of subjects free from MAEs in the Talent Control Group. The endpoint is defined as the proportion of subjects free from occurence of a MAE within 1 month of the implantation of the Endurant Stent Graft. The major adverse events composite endpoint which will be evaluated at 1 month post implant includes the occurrence of any of the following events.

* All-Cause Mortality

* Bowel Ischemia

* Myocardial Infarction

* Paraplegia

* Procedural Blood Loss \> or equal to 1000 cc

* Renal Failure

* Respiratory Failure

* Stroke

Primary Effectiveness Endpoint (Treatment Success)12 months

Treatment success is defined as Technical success and the following:

* Freedom from AAA diameter increased, defined as \>5 mm increase in maximum diameter as measured on CT scan (or MRA/MRI) at 12 months as compared to 1 month

* Freedom from Types I and III endoleaks at 12 months including those requiring intervention through 12 months

* Freedom from aneurysm rupture through 12 months

* Freedom from conversion to surgery through 12 months

* Freedom from stent graft migrations resulting in a serious adverse event or requiring secondary intervention through 12 months

* Freedom from stent graft occlusion at 12 months

Primary Effectiveness Endpoint (Technical Success)Intra-operatively

Technical success defined as successful delivery and deployment of the stent graft in the planned location and with no unintentional coverage of both the internal iliac arteries or any visceral aortic branches and with removal of the system. Technical success was assessed intra-operatively.

Primary Safety Endpoint (Freedom From MAEs Within 30 Days of Index Procedure)30 days (Safety)

The primary safety endpoint is composite defined as the proportion of subjects free from major adverse events (MAE) within 1 month (day 0 - Day 30)of implant is non-inferior to the proportion of subjects free from MAEs in the Talent Control Group. The endpoint is defined as the proportion of subjects free from occurence of a MAE within 1 month of the implantation of the Endurant Stent Graft. The major adverse events composite endpoint which will be evaluated at 1 month post implant includes the occurrence of any of the following events.

* All-Cause Mortality

* Bowel Ischemia

* Myocardial Infarction

* Paraplegia

* Procedural Blood Loss \> or equal to 1000 cc

* Renal Failure

* Respiratory Failure

* Stroke

Secondary Outcome Measures
