Summary
The Comaneci Embolization Assist Device is indicated for use in the neurovasculature as a temporary endovascular device used to assist in the coil embolization of wide-necked intracranial aneurysms with a neck width ≤ 10 mm. A wide-necked intracranial aneurysm (IA) defines the neck width as ≥ 4 mm or a dome-to-neck ratio < 2.
The objective of the Postmarket Surveillance Plan is to assess safety and performance as used in postmarket clinical practice in the U.S.
Eligibility Criteria
Inclusion Criteria
- Patient has a documented intracranial ruptured or unruptured aneurysm, suitable for embolization by coils.
- Patient is considered for treatment with coil embolization assisted by the Comaneci Device for wide-necked intracranial aneurysms with neck width ≤ 10 mm. A wide-necked intracranial aneurysm is defined by the neck width as ≥ 4 mm or a dome-to-neck ratio < 2.
- A signed informed consent by the patient or legally authorized representative
Exclusion Criteria
- Patient with known hypersensitivity to nickel-titanium
