Chimney EndoVascular Aneurysm Sealing Of New Expanded Indication

Prospective, multi-center, non-randomized study with consecutive, eligible subject enrollment at each site, for the evaluation of the ChEVAS System for Endovascular Repair of Complex Abdominal Aortic Aneurysms.

This is a prospective multicenter study with consecutive eligible subject enrollment at each site. Enrollment will include up to 150 subjects (120 ChEVAS subjects and up to 30 infrarenal roll-in subjects). The ChEVAS study will evaluate the safety and effectiveness outcomes following appropriate government and ethics committee/IRB requirements and guidelines. All enrolled (ChEVAS and Infrarenal) subjects will undergo a high resolution, contrast-enhanced computed tomography angiography (CT) scan of the relevant aortic and aortoiliac vasculature within three months of the scheduled procedure and at specified follow-up intervals post-implantation. Follow-up visits will occur at 30-days, 6-months, and annually to 5-years to assess aneurysm morphology, the status of the implanted devices, and relevant laboratory test results. \*As of October 27, 2021 ChEVAS ONE Study is voluntarily closed to screening and consenting. 13 subjects enrolled in the study will continue to be observed through 5-years.
