Brief Summary
The goal of this clinical trial is to evaluate the safety, performance, and Preliminary effectiveness of the iHub endoprosthesis system in treating iliac artery aneurysms in adult patients requiring endovascular repair. The study population includes both male and female adults over 18 years of age who meet the inclusion criteria for endovascular treatment of iliac artery aneurysms. The main questions it aims to answer are: Is the iHub stent-graft system safe for use in patients with iliac artery aneurysms? Does the iHub system demonstrate adequate technical performance and sustained patency over a 12-month follow-up period? Participants will undergo a minimally invasive endovascular procedure to implant the iHub endoprosthesis system. The device is designed to preserve internal iliac artery flow while excluding the aneurysmal segment. Participants will: Undergo pre-screening evaluations including clinical examination, laboratory tests, and imaging (CT angiography and ultrasound). Undergo endovascular implantation of the iHub device. Attend follow-up visits at 30, 90, 180, and 360 days post-implant to assess clinical outcomes and device performance.

Outcome Measures
Primary Outcomes (1)
Absence of serious adverse events related to the device in the first month after the procedure
Absence of serious adverse events related to the investigational device within 30 days after implantation. These events include, but are not limited to, stent-graft migration, vessel dissection, stent-graft obstruction, occlusion of collateral vessels, type I, III, and IV endoleaks, aneurysm rupture, and intraoperative mortality.
Within 30 days after implantation
Secondary Outcomes (1)
Absence of surgical conversion during the follow-up period from 3 to 12 months and device performance
Follow-up period from 3 to 12 months
Study Arms (1)
Endovascular Implant of iHub Iliac Stent-Graft for Treatment of Iliac Artery Aneurysms
EXPERIMENTALEligible participants with an iliac artery aneurysm, or aneurysms of the iliac arteries, who have iliac/femoral access compatible with the delivery systems, and a previously implanted or concurrently implanted bifurcated aortic stent-graft with branch diameters between 14 and 16 mm, will undergo endovascular surgery for aneurysm treatment using the iHub device
Interventions
Implantation of a self-expanding dual-lumen iliac branch stent-graft designed to treat iliac artery aneurysms while preserving perfusion to the internal iliac artery. The device enables connection to bridging stent-grafts directed to both the internal and external iliac arteries. It is compatible with previously implanted or concurrently implanted bifurcated aortic stent-grafts with branch diameters between 14 and 16 mm. The stent-graft is delivered endovascularly using a low-profile catheter-based system under fluoroscopic guidance. Once in position, the device is deployed via a controlled pull-back release mechanism. Radiopaque markers assist in precise alignment and facilitate the placement of bridging components.
Eligibility Criteria
You may qualify if:
- Meet at least one of the following criteria for iliac artery aneurysm:
- Common iliac artery aneurysm ≥ 25 mm in diameter;
- Aneurysm growth of 5 mm or more within the last six months;
- Maximum aneurysm diameter exceeds 1 to 1.5 times the normal arterial segment diameter, that is ≥ 25 mm maximum diameter;
- Saccular aneurysm greater than 20 mm;
- Abdominal aortic aneurysm with extension into the common iliac arteries of less than 20 mm;
- Have a previously implanted aorto-bi-iliac stent-graft with branch diameter between 14 and 16 mm;
- Have iliac/femoral access vessel morphology compatible with vascular access techniques, placement systems, devices, and/or accessories;
- Are classified as ASA physical status I to III. ASA IV patients may be included if their life expectancy is greater than one year;
- Are able and willing to comply with follow-up requirements during the 360-day post-implant period.
You may not qualify if:
- A dissection, rupture, or complex vascular lesion due to trauma;
- Need for emergency surgery;
- Contraindication to angiography;
- Diffuse atherosclerotic disease in any common iliac artery reducing its diameter to \< 4 mm;
- Congenital abnormalities where stent placement would obstruct a major artery. Such abnormalities must be assessed prior to treatment;
- Unstable angina;
- Class III obesity (BMI ≥ 40 kg/m²) or other clinical conditions that severely limit radiographic visualization of the aorta;
- Connective tissue disease (e.g., Marfan or Ehlers-Danlos syndrome);
- Hypercoagulable state;
- Contraindication to anticoagulation therapy;
- Acute or chronic renal insufficiency (serum creatinine \> 2.0 mg/dL);
- Life expectancy of less than one year;
- Presence of a systemic infection that could increase the risk of endovascular device infection;
- Known sensitivity or allergy to device materials: expanded polytetrafluoroethylene (ePTFE), fluorinated ethylene propylene (FEP), or nickel-titanium (Nitinol).
