The proposed study is a multi-center single arm retrospective and prospective data collection, of patients treated with the LVIS device of specific sizes of 3.5mm, 4.0mm, 4.5mm, 5.5mm with up to 5 years follow-up. Information collected during the study will be standardized across centers to include pre-treatment baseline characteristics of patients including aneurysm(s) symptoms, procedural information, prespecified clinical safety events of interest, and follow-up imaging, clinical visits or telephone calls.
