Exclusion Criteria: Subjects with a minimum platelet count of \< 100,000/μL. Subjects who have suffered an ischemic stroke or transient ischemic attack within the past 30 days. Subject has an acutely ruptured aneurysm with a Hunt \& Hess score ≥ 4 Subject has an infectious, blister-like, fusiform, dissecting, traumatic or mycotic aneurysm confirmed by angiography Subject has challenging anatomy that in the investigator's opinion is not suitable for safe delivery of an 0.021" catheter, including stenosis \> 70% or excessive tortuosity Subject presents with other medical or surgical co-morbidities limiting his/her life expectancy to less than one year Subject is, in the opinion of the investigator, unlikely to comply with the study protocol or follow-up requirements.

Subject has serious concurrent medical conditions including bacteremia or sepsis, acute renal failure at the time of the procedure, and major coagulation system abnormalities that in the opinion of the investigator could significantly increase risk Subject has severe intracranial vasospasm not responsive to medical therapy Subject has chronic kidney disease stage ≥ 4 and is not undergoing dialysis The subject is pregnant or breastfeeding at the time of admission or plans to become pregnant during their participation in the trial Subject is currently participating in another clinical research trial involving an investigational device or drug Subject is under judicial protection or legal guardianship
