Clinical Trial 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.

Primary	Periprocedural events	Rates of all adverse events occurring within 24 hours post-procedure and hospital discharge status.	24 Hours post procedure
Primary	Adverse events	All adverse events at discharge and up to 30 days post procedure.	30 days post procedure
Primary	Functional status	Functional status at discharge and 30 days assessed using the modified Rankin Scale (mRS).; using the modified Rankin Scale (mRS). This scale runs from 0-6, from no symptoms to death as follows: 0 - No symptoms; 1 - No significant disability. Able to carry out all usual activities, despite some symptoms.; 2 - Slight disability. Able to look after own affairs without assistance, but unable to carry out all previous activities.; 3 - Moderate disability. Requires some help, but able to walk unassisted.; 4 - Moderately severe disability. Unable to attend to own bodily needs without assistance, and unable to walk unassisted.; 5 - Severe disability. Requires constant nursing care and attention, bedridden, incontinent.; 6 - Dead.	30 days post procedure
Primary	Successful intracranial aneurysm occlusion	Successful intracranial aneurysm occlusion (measured by Raymond Roy classification I or II) at the end of procedure, using digital subtraction angiography (DSA).	end of procedure
Primary	Successful intracranial aneurysm (IA) occlusion	Successful intracranial aneurysm (IA) occlusion, that is a stable IA occlusion, measured by Raymond Roy classification I or II taken at 6 months (± 21d) post procedure without the need for re-treatment of the target IA, using DSA.	6 Months Post procedure
Primary	Good clinical outcome	Good clinical outcome- mRS shift @ 6 months (change @ 6 months from pre procedure) and tetrachotomized (0,1, 2, 3-6) mRS analysis	6 Months Post procedure
