Outcome Measures
Primary Outcomes (2)
Safety: Procedure and Device-Related Adverse Events
Absence of major events (procedure and device-related) within the 1-month follow-up visit
Up to 30 days
Efficacy: Successful delivery of the EAST System into the AAA sac
Successful insertion of the delivery catheter and delivery of the Stabilizer Compound
Up to 30 days
Secondary Outcomes (2)
Efficacy: Evaluation of the AAA sac diameter over the 36 month follow up period.
Through study completion, an average of 3 years
Efficacy: Evaluation of the AAA sac shrinkage over the 36 month follow up period.
Through study completion, an average of 3 years
Study Arms (1)
Interventional
EXPERIMENTALUse of the EAST System for the stabilization treatment of AAA. The device is delivered endovascularly and placed in the AAA sac to deliver the Stabilizer Infusion Solution.
Interventions
Endovascular procedure: an ipsilateral ilio-femoral aortogram to confirm suitability for placement of a 14F sheath will be performed. A baseline contrast aortogram will be performed to assess vessel patency and target location of the EAST delivery catheter. Occluding and Stabilizer balloons are inflated in preparation for Stabilizer Compound delivery within the AAA sac. A post-Stabilizer angiogram will re-assess vessel patency and aorta stability. Delivery catheter is removed and discarded. The entire procedure is approximately one hour.
Eligibility Criteria
You may qualify if:
- Male or Female aged 18 years or older
- Subject can understand the purpose of the trial, voluntarily participate in the trial and sign the informed consent and is willing to complete the follow-up according to the requirements of the protocol.
- Infrarenal non-aneurysmal neck ≥15mm in length
- Aortic neck diameters ≤ 29mm
- Infrarenal neck angulation ≤ 60°
- Abdominal aneurysm from 3.5 cm to 5.0 cm.
- Overall AAA treatment length (distal renal to distal inferior margin of the aneurysm) not to exceed 10 cm
- Patient iliac or femoral arteries access vessels' size and morphology allow endovascular access of 14F introducer sheaths and catheters.
- Subject has \> one-year life expectancy.
- Subject is American Society of Anesthesiology (ASA) grade 1 through 3, inclusive.
- Subject is able and willing to comply with 1, 3, 6, 12, 24 and 36-month follow-up.
You may not qualify if:
- Subject has an acutely ruptured or leaking or emergent aneurysm.
- Subject has a dissecting aneurysm.
- Subject has a mycotic or infected aneurysm.
- Subject has current vascular injury due to trauma.
- Subject's aneurysm is thoracic or suprarenal.
- Previous surgical or endovascular aneurysm repair for abdominal aortic aneurysm.
- Subject has thrombus, calcification, and/or plaque that may compromise delivery.
- Subject has had a myocardial infarction within six (6) months prior to enrollment.
- Subject has current angina or other active cardiac condition such as congestive heart failure, untreated or worsening atrial arrhythmia, ventricular arrhythmia, or valvular disease.
- Subject has undergone other major surgery within the 30 days prior to enrollment.
- Subjects with any transient ischemic attack (TIA) or ischemic stroke within 3 months.
- Known allergy to polyester or contrast material that cannot be pretreated.
- Subject is morbidly obese or has other clinical conditions that severely inhibit X-ray visualization of the aorta.
- Subject has connective tissue disease (e.g., Marfan syndrome, Eaton syndrome, or Bessel's disease).
- Known contraindication to undergoing angiography or anticoagulation.
