Eligibility Criteria

Inclusion

  • ≥18 years of age
  • A candidate for elective EVAR of an infrarenal fusiform aortic aneurysm ≥5.5 cm in diameter in men and ≥5.0 cm in women;
  • Thrombus burden (percentage of the AAA sac occupied by thrombus) \<50%, based on pre-procedure CTA
  • Maximum Lumen diameter within the AAA sac of ≥40mm.
  • The predicted minimum number of IMPEDE-FX RapidFill Implants for the subject is ≤200.

Exclusion

  • General
  • An inability to provide informed consent.
  • Enrolled in another clinical study that could interfere with the outcomes being studied in this trial.
  • Unable or unwilling to comply with study follow-up requirements.
  • Prisoner or member of other vulnerable population
  • Anatomical
  • Concomitant iliac artery ectasia or aneurysm
  • Vascular disease and/or anatomy that preclude the safe access and positioning of a catheter to deliver the investigational product into the AAA sac.
  • Ruptured, leaking, inflammatory or mycotic (infected) aneurysm.
  • Connective tissue disorder (e.g., Marfan's syndrome)
  • Aneurysmal disease of the descending thoracic aorta
  • Excessive calcification at the aortic bifurcation to common/internal iliac bifurcation, that might lead to access difficulties
  • EVAR/Procedural
  • 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

  • Planned use of the chosen stent graft outside its instructions for use (IFU)
  • Use of fenestrated stent grafts or chimney techniques
  • Use of the Heli-FX EndoAnchor system
  • Use of embolic devices other than the investigational product to embolize the AAA sac
  • Use of embolic products to prophylactically or concomitantly embolize the inferior mesenteric artery, lumbar arteries, renal accessory arteries, or internal iliac arteries
  • Inability to land the distal-most portion of the EVAR stent graft limbs, including extensions, above the internal iliac arteries
  • Medical History/Conditions

  • Atrial fibrillation that is not well rate controlled
  • Life expectancy of \<2 years post-procedure
  • Known hypersensitivity or contraindication to platinum, iridium, or polyurethane.
  • Have active infection at the time of the index procedure documented by pain, fever, drainage, positive culture, or leukocytosis (WBC \>11,000/mm3)
  • A condition that inhibits radiographic visualization during the implantation procedure
  • History of allergy to contrast medium that cannot be managed medically, or subject is unable to have a CT with contrast for any reason.
  • Uncontrolled co-morbid medical condition, including mental health issues, that would adversely affect participation in the trial
  • 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
