Inclusion Criteria

• •Aneurysm dome diameter must be ≤ 10mm and within the diameter (and parent vessel diameter, as appropriate) range treatable by commercially available WEB devices as well as at least one other alternative commercially available endovascular treatment device used per hospital standard practice
• •Aneurysm is located on the anterior communicating artery complex segment (ACom), internal carotid artery terminus (ICAt), anterior cerebral artery (ACA), middle cerebral artery (MCA), basilar apex, posterior communicating artery (PCom) or pericallosal artery
• •Patient must be neurologically stable with a Hunt \& Hess score of I to III
