The goal of this clinical trial is to collect additional data to demonstrate if the Contour Neurovascular System (CNS) is a safe and effective treatment of wide-necked, saccular, intracranial aneurysms.
Participants will:
Undergo treatment with the Contour Neurovascular System Complete follow-up visits at 1month, 12months, and 24 months, following their procedure Report any adverse events to their study team

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria
. Patient is 18-75 years of age at the time of screening.
. Patient has a single ruptured or unruptured IA requiring treatment. If the patient has an additional IA requiring treatment, the additional IA must not require treatment within 60 days after the index procedure.
. The target IA must have the following characteristics:
. Patient may be treated with Contour without the use of additional implanted devices.
. Patient is able to comply with all aspects of the screening, evaluation, treatment, and the post-procedure follow-up schedule.
. Patient or legally authorized representative has signed and dated an institutional review board (IRB)/Ethics Committee (EC)-approved written informed consent prior to initiation of any study procedures.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Incidence of death or stroke within 30 days of treatment or ipsilateral stroke or neurological death between 30 days and 1 year.
Timeframe: From enrollment to 1 year
2
Proportion of complete occlusion of the aneurysm with Contour, without retreatment, recurrent subarachnoid hemorrhage, or significant parent artery stenosis at one (1) year after treatment.
. Patient meets the criteria outlined in the "Guidelines for the Management of Patients With Unruptured Intracranial Aneurysms" as published by the AHA/ASA\^6
. Patient meets the criteria outlined in the "Guidelines for the Management of Aneurysmal Subarachnoid Hemorrhage: A Guideline for Healthcare Professionals from the American Heart Association/American Stroke Association" as published by the AHA/ASA.\^6
Exclusion criteria
. Anatomy or physiology considered unsuitable for endovascular treatment with the Contour device by the implanting physician and/or the Patient Selection Committee
. Target IA contains other devices/implants (e.g., coils) that could interfere with the correct placement of the Contour device
. Subject has a known, untreatable hypersensitivity to contrast dye, iodine, or any component of the treatment device.
. Contraindication to anticoagulants or anti-platelet medications
. Stenosis of the target IA's parent vessel is \>50%
. Anticoagulation medications (e.g., warfarin) that cannot be discontinued
. Acute / chronic renal failure (unless on dialysis) or creatinine \> 2.00 mg/dl or \> 182 μmol/L
. Vascular disease or other vascular anomaly that precluded the necessary access to the aneurysm for use of the study device.
