A Study to Look at Performance of MICRUSFRAME and GALAXY Coils for the Treatment of Intracranial Aneurysms

1. Packing Density

Packing density will be evaluated based on aneurysm volume and the coils used during the procedure.

Time frame: From enrollment to end of treatment at 12 months

2. Complete occlusion rate

Complete occlusion rate at 12 month follow-up

Time frame: 12 month

3. Recanalization Rate

Recanalization Rate: Any worsening of occlusion grading at 12 Month follow-up

Time frame: 12 Months

4. Device related serious adverse events

Any device related serious adverse events will be reported through 12 month follow-up

Time frame: 12 Months

5. Retreatment Rate

Aneurysm re-treatment rates will be tracked and recorded during the 12 month follow-up

Time frame: 12 Months

6. Modified Rankin Score

Modified Rankin Score (Scale from 0-6) at 12 Months. 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.
