A safety study of Neucrylate AN™ Liquid Embolic System for the treatment of cerebral berry aneurysms

1. Neurological assessments will be done using the Glasgow Coma Scale, Hunt and Hess Scale, and Modified Rankin Score. These will be done at Screening, Procedure Day, Post-procedure Day 1, Hospital Discharge, Week 6, and at the Month 6 Visit.
2. Aneurysm filling will be assessed using the following scale on Procedure Day and at the Month 6 Visit:
i. 0 - 24% filling
ii. 25 - 49% filling
iii. 50 - 74% filling
iv. 75 - 89% filling
v. 90% filling or more
3. Major Adverse Events (MAEs): During the implant procedure and for the 6-month follow-up period, all of the deaths, major strokes (resulting in a Modified Rankin score of >=3), and haemorrhages from the treated aneurysm will be documented.

1. Adverse Events (AEs) and Serious Adverse Events (SAEs): During the implant procedure and for the 6-month follow-up period, all of the adverse events and serious adverse events will be documented. The investigator will provide his/her opinion, based on clinical experience and judgment, on the relationship between the event and either: (a) the procedure done to implant Neucrylate™, or (b) the presence of the Neucrylate™ in the body.
2. Unwanted device: Unwanted passage of device beyond the aneurysm in the parent vessel, or prior to reaching the aneurysm, on a 6-point scale:
i. No device in brain arteries noted
ii. Device in brain arteries that compromise <=25% of the arterial lumen
iii. Device in brain arteries that compromise 26-50% of the arterial lumen
iv. Device in brain arteries that compromise 51-75% of the arterial lumen
v. Device in brain arteries that compromise >=75% of the arterial lumen
vi. Device completely occludes arterial lumen
3. User acceptability: For all three user acceptability measures (1) visibility of material, (2) ease of introduction, and (3) ease of delivery, assessments will be recorded.
