Brief Summary:
The purpose of this clinical study is to evaluate the safety and device performance of the Nellix® EndoVascular Aneurysm Sealing System (Nellix System) for the treatment of infrarenal abdominal aortic aneurysms.

Condition or disease Intervention/treatment Phase
Abdominal Aortic Aneurysms Device: The Nellix® EndoVascular Aneurysm Sealing System Not Applicable

Detailed Description:
This is a multicenter, multi-country prospective, single-arm, non-randomized clinical trial. The comparative control arm is a combination of patient data drawn from the abdominal aortic aneurysms (AAA) open surgical control arms of four commercially approved AAA devices as part of the Society of Vascular Surgeons. Patients enrolled in this study will be pre-screened and have a diagnosis of an infrarenal AAA with or without the need for treatment of iliac artery aneurysm, are candidates for endovascular repair, and meet the eligibility criteria. Patients enrolled in the study will participate in follow-up visits 31 days, 6 months and at 1 year following the index procedure. At the follow-up visits there will be a clinical assessment, blood collection, and abdominal CT imaging of the patient.

Experimental: Nellix Aneurysm Sealing
The Nellix® EndoVascular Aneurysm Sealing System
Device: The Nellix® EndoVascular Aneurysm Sealing System

Primary Outcome Measures :
  1. Safety [ Time Frame: 30 day ]
    The primary safety endpoint is defined as the incidence of Major Adverse Events (MAE) through 30 days after the index procedure.

  2. Device Performance [ Time Frame: 30 days ]
    The primary performance endpoint is technical success defined as successful delivery and deployment of the device and freedom from open surgical conversion at 30 days.

Secondary Outcome Measures :
  1. All Cause Mortality [ Time Frame: 12 months ]
    Any death occurring during the study period, regardless of cause

Inclusion Criteria:

  • At least 18 years of age
  • Informed consent form understood and signed and patient agrees to all follow-up visits
  • Is able and willing to comply with clinical follow-up requirements for one year
  • Is able and willing to undergo Contrast-Enhanced Spiral CT scans
  • Is a candidate for endovascular repair of an infrarenal aortic aneurysm with or without an iliac aneurysm with at least one of the following;

    1. aneurysm ≥ 4.5 cm in diameter, or
    2. aneurysm is twice the diameter of the normal infrarenal aorta, or
    3. aneurysm is growing at a rate of ≥ 10 % per year
