Primary Outcome Measures
NameTimeMethod
The rate of major adverse events.30 days

Adverse events defined as the composite endpoint of death, significant blood loss requiring intervention, respiratory failure, myocardial infarction, renal failure, paralysis, stroke, bowel ischemia and/or device migration causing vascular compromise.

Secondary Outcome Measures
NameTimeMethod
Feasibility of device defined by clinical and technical success6 months, 1 year and 2 years

Evaluate the feasibility of using Altura AAA Endograft. Feasibility is comprised of acute clinical and technical success measured at the time of procedure. Long-term safety will be evaluated at 6 months, 1 year and 2 years.
