* Aortoiliac aneurysm, or concomitant iliac artery ectasia or aneurysm (common iliac artery diameter \>24 mm) close to the bifurcation and/or that cannot be adequately sealed
* Patent AAA sac feeding vessels (within the sac) \>4 mm in diameter
* Volume of AAA sac to be filled after stent graft placement \<20 mL or \>135 mL, based on pre-procedure CTA (i.e. aortic flow volume exclusive of stent graft volume)

* Planned use of the chosen stent graft outside its instructions for use (IFU)
* Planned use of fenestrated or chimney stent grafts
* Study participants in which stent graft placement is abandoned for any reason, and/or in which the investigator decides, during the course of the stent graft placement, that the study procedure may not be appropriate
* Planned use of embolic devices other than the investigational product to embolize the AAA sac
* 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, or mycotic (infected) aneurysm
* Aneurysmal disease of the descending thoracic aorta
* Coagulopathy or uncontrolled bleeding disorder
* Long-term (\>6 months prior to the procedure) use of direct oral anticoagulant or any vitamin K antagonist anticoagulant use
* Serum creatinine level \>2.5 mg/dL;
* Cerebrovascular accident within 3 months prior to the procedure
* Myocardial infarction and/or major heart surgery within 3 months prior to the procedure
* Atrial fibrillation that is not well rate controlled
* Unable or unwilling to comply with study follow-up requirements
* Life expectancy of \<2 years post-procedure
* Known hypersensitivity or contraindication to platinum, iridium, or polyurethane
* A condition that inhibits radiographic visualization during the implantation procedure
* History of allergy to contrast medium that cannot be managed medically
* Uncontrolled co-morbid medical condition, including mental health issues, that would adversely affect participation in the study
* Pregnant or a 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 study
* Prisoner or member of other vulnerable population.
Primary outcome measure(s)
Incidence of related major adverse events (MAEs) — 30 days post-procedure Incidence of related major adverse events (MAEs)
Efficacy - Technical Success — Immediately after the intervention Technical success, defined as filling of the residual flow lumen of the AAA sac with investigational products
