Eligibility Criteria
Inclusion Criteria
- Subject has provided written Data Release Form (DRF) or informed consent using the Institutional Review Board (IRB)/ Ethic Committee (EC)-approved consent form and agrees to comply with protocol requirements.
- At least 18 years of age.
- Subject has already been selected for flow diversion therapy as the appropriate treatment.
- Subject has a target IA that has a parent vessel with diameter 1.5-5.0 mm distal/proximal to the target IA.
Exclusion Criteria
- Major surgery including endovascular procedures within the past 30 days.
- Subject with target IA located in the basilar artery
- Subject with anatomy not appropriate for endovascular treatment due to severe intracranial vessel tortuosity or stenosis determined from baseline or pre-procedure imaging, or a history of intracranial vasospasm not responsive to medical therapy.
- Stent is in place in the parent artery at the target IA location.
- Subject with an acutely (within 30 days) ruptured aneurysm with a Hunt and Hess grade of 4 or higher.
- Any known contraindication to treatment with the Pipeline™ Flex Embolization Device with Shield Technology™ per Instructions for Use.
- The investigator determines that the health of the subject or the validity of the study outcomes (e.g., high risk of neurologic events, conditions that may increase the chance of stroke, worsening of clinical condition in the last 30 days) may be compromised by the subject's enrollment.
- Pregnant or breast-feeding women or women who wish to become pregnant during the length of study participation.
- Subject is currently enrolled or planning to participate in a potentially confounding drug or device trial during the course of this study. Co-enrollment in concurrent trials is only allowed when documented pre-approval is obtained from Medtronic.
- Legal incapacity or evidence that a subject cannot understand the purpose and risks of the study or inability to comply fully with study procedures.
