Brief Summary
The goal of this prospective, observational study is to evaluate the long-term occlusion rates and safety of the Penumbra PC400 coil in the treatment of ruptured and unruptured intracranial aneurysms in adult subjects ages 18-80. Specifically, the study aims to analyze rate of death, stroke, neurological death, or rebleeding associated with the treatment of intracranial aneurysm with the PC400 coil. Participants will undergo standard of care treatment and follow up for their aneurysm treatment, and participating sites will collect procedural and follow up data.

Outcome Measures
Primary Outcomes (3)
Procedure- or disease-related death or major stroke
Procedure- or disease-related death or major stroke within 30 days of treatment
30 days post-procedure
Stroke, neurological death, or rebleeding from target aneurysm
Major ipsilateral stroke, neurological death or rebleeding from the target aneurysm during the 18-month follow-up period
18 months post procedure
Adequate angiographic occlusion
Adequate angiographic occlusion at 18 ± 6 months without interim retreatment secondary to aneurysm recurrence or rebleed of the target aneurysm. This will be assessed by the core lab using digital subtraction angiograms (DSA).

Eligibility Criteria
All eligible subjects presenting to a participating study site will be considered for enrollment. Up to 100 patients ≥ 18 and ≤ 80 years presenting with ruptured or unruptured saccular aneurysms who meet all eligibility criteria will be enrolled. Enrolled subjects must be treated with Penumbra PC400 coils used in any combination comprising a minimum of 80% total coil length used.
You may qualify if:
- Subject is ≥ 18 and ≤ 80 years of age.
- Subject has a previously untreated, ruptured or unruptured, saccular intracranial aneurysm 5mm or more in diameter for which the clinical decision to treat with Penumbra PC400 embolization coils has been made independent of the decision to enroll the subject in the study described in this protocol.
- The decision to undergo the coiling procedure is made independently of and prior to participation in the research.
- Subject has a baseline Hunt and Hess Score of I, II, or III.
- Subject must be considered by the treating physician to be available for and able to complete all follow-up visits.
- Subject has not been previously entered into this study.
You may not qualify if:
- Subject is \< 18 or \> 80 years of age.
- Subject has a baseline Hunt and Hess score of IV or V.
- Target aneurysm is dissecting, fusiform, blister-like, mycotic, tumoral, or AVM related.
- Target aneurysm maximum diameter is \<5mm
- Target aneurysm was previously treated via clipping or coiling.
- Target aneurysm is deemed by the treating physician to be unsuitable for coiling or unlikely to be successfully treated by endovascular techniques.
- Target aneurysm has not been confidently determined by the treating physician to be the source of SAH.
- Planned use of a flow diverter (Surpass, Pipeline, Silk, FRED, p64, etc.) or intrasaccular device (WEB, Artis, Medina, etc.) as a component of the target aneurysm treatment plan.
- Intended use of a coil-assist stent as a component of the target aneurysm treatment plan, unless stent is used for bailout purposes.
- Subject has a known, untreatable hypersensitivity to contrast dye, iodine, hydrogel, or any other component of the treatment device.
- Subject has a contraindication to heparin or aspirin.
- Subject has vascular anatomy/tortuosity preventing access to the target aneurysm.
- Subject is unable to undergo DSA or DSA is determined unsuitable or outside standard of care by the treating physician.
- Subject has a serious or life-threatening comorbidity that could confound study results.
- Subject is at high risk of noncompliance due to a history of substance abuse, psychosocial issues, etc.
