Brief Summary:
Prospective, multicenter, single arm study with consecutive, eligible subject enrollment at each site. All subjects will undergo the Endovascular Aneurysm repair procedure with the Nellix System.

Condition or disease Intervention/treatment Phase
Abdominal Aortic Aneurysm Without Rupture Device: Nellix® System Not Applicable

Detailed Description:
This study will evaluate the safety and effectiveness of the Nellix System among a wide range of physicians and in consecutively enrolled subjects to assess safety and effectiveness outcomes. Following appropriate government and ethics committee/IRB approval the Nellix® EndoVascular Sealing System will be implanted into eligible patients who are adequately informed and have consented to join the study. Enrolled patients 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.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 98 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Intervention Model Description: Prospective, multicenter, single arm study with consecutive, eligible subject enrollment at each site. All subjects will undergo the Endovascular Aneurysm repair procedure with the Nellix System. Sites have been chosen with a suitable research infrastructure and physician experience in endovascular aneurysm repair to ensure adequate enrollment. Subjects will be followed procedurally to discharge, at 30 days (primary safety endpoint), six months, one year (primary effectiveness endpoint) and annually thereafter to five years (total follow-up commitment).
