Brief Summary
The objective of this study is to generate contemporaneous clinical data to facilitate a reasonable comparison of the performance of the FRED™ X™ device with the performance of the FRED™ device. The data generated from this study will be compared to the safety and effectiveness of the FRED™ device by meeting the same performance goals (PGs) established for the FRED™ pivotal study.

Primary Outcomes
Outcome Description
Major stroke is defined as a new neurological event that persists for \>24 hours and results in a ≥4-point increase in the NIHSS score compared to baseline or compared to any subsequent lower score.
Outcome Measure
Primary Safety Endpoint Part 1: Proportion of subjects that experience either Death or major stroke within 30 days post-procedure.
Outcome Time Frame
30-days
Outcome Description
A major ipsilateral stroke is defined as that occurring within the vascular distribution of the stented artery. Neurological death is defined as a death which has been adjudicated by an independent clinical events committee to have directly resulted from a neurologic cause.
Outcome Measure
Primary Safety Endpoint Part 2: Proportion of subjects that experience neurological death or major ipsilateral stroke within 12 months post-procedure.
Outcome Time Frame
12 months
Outcome Description
(1) Complete (100%) occlusion of the target aneurysm is assessed utilizing the Raymond-Roy Scale (Raymond Roy Class 1) and ≤50% stenosis of the parent artery at the target IA), and in whom an alternative treatment of the target IA had not been performed. The study will utilize independent Core Laboratory to adjudicate all angiographic outcomes, including aneurysm occlusion status and parent artery stenosis. (2) Alternative treatment is defined as re-treatment of the target aneurysm with an alternative treatment modality including open repair, endovascular placement of an additional stent or treatment of in-stent stenosis.
Outcome Measure
Primary Effectiveness Endpoint: The percent of subjects with (1) complete (100%) occlusion of the target aneurysm and ≤50% stenosis of the parent artery at the target IA, and (2) in whom an alternative treatment of the target IA had not been performed.
