Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - IMPEDE-FX RapidFill Implants
Treatment: Surgery - EndoVascular Aneurysm Repair

Experimental: Treatment - Treatment Arm: Subjects in the treatment arm will have both an EVAR device and IMPEDE-FX RapidFill implants inserted.

Active comparator: Control - Control Arm: Subjects in the control arm will only have an EVAR device implanted.

Key exclusion criteria
General

1. An inability to provide informed consent.
2. Enrolled in another clinical study that could interfere with the outcomes being studied in this trial.
3. Unable or unwilling to comply with study follow-up requirements.
4. Prisoner or member of other vulnerable population

Anatomical

1. Concomitant iliac artery ectasia or aneurysm
2. Vascular disease and/or anatomy that preclude the safe access and positioning of a catheter to deliver the investigational product into the AAA sac.
3. Ruptured, leaking, inflammatory or mycotic (infected) aneurysm.
4. Connective tissue disorder (e.g., Marfan's syndrome)
5. Aneurysmal disease of the descending thoracic aorta
6. Excessive calcification at the aortic bifurcation to common/internal iliac bifurcation, that might lead to access difficulties

EVAR/Procedural

1. Use of aortic stent grafts other than the Gore Excluder AAA Endoprosthesis, Gore Excluder Conformable AAA Endoprosthesis, Cook Zenith Flex AAA Endovascular Graft, Medtronic Endurant II and Endurant IIs Stent Graft, or the Terumo TREO Stent Graft to treat the AAA
2. Use of an aortic stent graft other than those specified1 for a particular site
3. Planned use of the chosen stent graft outside its instructions for use (IFU)
4. Use of fenestrated stent grafts or chimney techniques
5. Use of the Heli-FX EndoAnchor system
6. Use of embolic devices other than the investigational product to embolize the AAA sac
7. Use of embolic products to prophylactically or concomitantly embolize the inferior mesenteric artery, lumbar arteries, renal accessory arteries, or internal iliac arteries
8. Inability to land the distal-most portion of the EVAR stent graft limbs, including extensions, above the internal iliac arteries

Medical History/Conditions

1. Coagulopathy or uncontrolled bleeding disorder
2. Serum creatinine level >2.5 mg/dL
3. Cerebrovascular accident within 3 months prior to the procedure
4. Myocardial infarction and/or major heart surgery within 3 months prior to the procedure
5. Atrial fibrillation that is not well rate controlled
6. Life expectancy of <2 years post-procedure
7. Known hypersensitivity or contraindication to platinum, iridium, or polyurethane.
8. Have active infection at the time of the index procedure documented by pain, fever, drainage, positive culture, or leukocytosis (WBC >11,000/mm3)
9. A condition that inhibits radiographic visualization during the implantation procedure
10. History of allergy to contrast medium that cannot be managed medically, or subject is unable to have a CT with contrast for any reason.
11. Uncontrolled co-morbid medical condition, including mental health issues, that would adversely affect participation in the trial
12. Pregnant or lactating female: for females of child-bearing potential, based on a positive pregnancy test within 7 days prior to the procedure or refusal to use a medically accepted method of birth control for the duration of the trial
