Description of intervention(s) / exposure
Treatment: Devices - Pipeline™ Flex Embolization Device with Shield Technology™

Treatment: Devices: Pipeline™ Flex Embolization Device with Shield Technology™
Pipeline™ Flex Embolization Device with Shield Technology™ utilizes a phosphorylcholine (PC) surface treatment to the implant combined with the PFED delivery system. The Shield Technology™ surface treatment applied to the implant is an inert polymer material created to mimic the outer membrane of a human red blood cell.
The Pipeline™ Flex Embolization Device with Shield Technology™ is intended for endovascular embolization of cerebral aneurysms and is designed to be placed across the opening (or 'neck') of a brain aneurysm and redirect blood flow away from the aneurysm, causing the blood within the aneurysm to clot.

Key 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
Minimum age

Can healthy volunteers participate?
Key exclusion criteria
- Major surgery including endovascular procedures within the past 30 days.

- Subject with anatomy not appropriate for endovascular treatment.

- Stent is in place in the parent artery at the target IA location.

- 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.

- Legal incapacity or evidence that a subject cannot understand the purpose and risks of
the study or inability to comply fully with study procedures.
