Inclusion Criteria: * 18 years or older * Understands and has signed an Informed Consent * Candidate for endovascular or open surgical repair of an infrarenal aortic or aorto-iliac aneurysm * Abdominal aneurysm \> 45 mm or aneurysm growth of \> 10 mm/year * Abdominal aneurysm neck angulation ≤ 60 degrees * Infrarenal non-aneurysmal neck 15 mm * Infrarenal non-aneurysmal neck diameter between 18 and 28 mm, inclusive * Iliac artery landing zone 15 mm in length * Iliac artery landing zone diameter between 8 and 18 mm, inclusive * Patent iliac and femoral arteries, access vessels, size and morphology, to allow endovascular access of a minimum 14 Fr introducer sheath and catheter * Ability to preserve at least one hypogastric artery * Life expectancy \> one year * American Society of Anesthesiology (ASA) grade 1 through 3, inclusive * Able and willing to comply with follow-up visits at 30 days, 6 and 12 months and annually through 5 years Exclusion Criteria: * Pregnant or nursing * An acutely ruptured, leaking or emergent aneurysm * An aortic dissection (Type A or B) * A mycotic, infected or inflammatory aneurysm * A thoracic, suprarenal or juxtarenal aneurysm * Previous surgical or endovascular aneurysm repair for abdominal aortic aneurysm or an aorto-iliac aneurysm * Severe iliac artery tortuosity * Thrombus, calcification and/or plaque that may complicate sealing * Evidence or history of intracranial bleeding or aneurysm, myocardial infarction or stroke within the past 3 months * Current angina or other active cardiac condition such as congestive heart failure, untreated or worsening atrial arrhythmia, ventricular arrhythmia or valvular disease * Had or plans to have an unrelated major surgical or interventional procedure within 1 month before or after implantation of the study device * Significant (\>80%) diameter renal artery stenosis which could not be readily treated * Known sensitivity or allergy to nitinol or polyester * Known hypersensitivity or contraindication to anticoagulation or contrast media that is not amenable to pre-treatment * Contraindication to antiplatelet, anticoagulant or thrombolytic therapy; * Coagulopathy or uncontrolled bleeding disorder * History of heparin-induced thrombocytopenia (HIT) * Clinically and morbidly obese such that the required imaging would be prevented * Connective tissue disease (e.g., Marfan's or Ehlers-Danlos syndromes) * Currently on dialysis or has compromised renal function as reflected by a serum creatinine \>2.0 mg/dL * Compromised hepatic function * Active infection at the time of the index procedure * End-stage chronic obstructive pulmonary disorder (COPD) * Religious, cultural or other objections to the receipt of blood or blood products * Participating in another research study involving an investigational device or drug which may potentially affect study results * Other medical, social or psychological problems that, in the opinion of the Investigator, preclude them from receiving this treatment and the procedures and evaluations pre- and post-treatment
