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
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.
Saccular morphology
Located at a bifurcation in the anterior or posterior circulation
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
