Description of intervention(s) / exposure
Treatment: Devices - Endovascular Aneurysm Stabilization Treatment (EAST)

Experimental: Interventional - Use 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.


Treatment: Devices: Endovascular Aneurysm Stabilization Treatment (EAST)
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.

- 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.
