Brief Summary
The objective of this post-market trial is to evaluate Endologix AFX endovascular AAA system with anatomical fixation against other approved Endovascular systems with proximal fixation. Multiple U.S clinical centers will be involved in the trial to include a broad range of experience. Imaging data will be evaluated by an independent core lab.

1 year
Secondary Outcomes (14)
The Number of MAEs
At 30 days, 12 months, and annually up to five years
The Number of Participants With Aneurysm Related Complications (ARC)
Post 12 Months up to Five Years
The Number of Participants With Aneurysm Related Mortality
Up to Five Years
Number of Type Ia Endoleaks
Up to Five Years
Number of Type Ib Endoleaks
Up to Five Years
- +9 more secondary outcomes
Study Arms (2)
AFX EVAR AAA Graft System
ACTIVE COMPARATORSubjects randomized to receive the Endologix AFX Endovascular Graft System for implantation to repair Abdominal Aortic Aneurysm via femoral access.
FDA Approved EVAR AAA Graft Systems
ACTIVE COMPARATORSubjects randomized to receive the comparator AAA Endovascular Graft System for implantation to repair Abdominal Aortic Aneurysm via femoral access.
Interventions
Endvovascular Abdominal Aneurysm Repair (EVAR) using commerically available, FDA approved endovascular graft systems implanted via femoral access.
Eligibility Criteria
You may qualify if:
- Male or female at least 18 years old
- Subjects with minimum of 2 year life expectancy
- Subjects have signed the informed consent document for data release
- Subjects with infrarenal AAA who are assessed by the Investigator to be eligible for endovascular Abdominal Aortic Aneurysm Repair with the trial devices.
You may not qualify if:
- Currently participating in another study where primary endpoint has not been reached yet
- Known allergy to any of the device components
- Pregnant (females of childbearing potential only)
- Subjects with pre-existing EVAR, e.e. in need of repair/intervention of a previously failed EVAR
