Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Clinical success rate Clinical success is defined as meeting all of the following three conditions: 1. Angiography 6 months after treatment shows that the coil mass is maintained within the cerebral aneurysm 2. Angiography 6 months after treatment shows that a curative occlusion has been achieved 3. No additional treatment*3 was performed on the treated aneurysm within 6 months | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Technical success of treatment (proper implantation of the investigational device and placement of the coil mass into the cerebral aneurysm) 2. Procedural success of treatment (technically successful with no serious adverse events and/or device malfunctions attributable to the treatment or procedure) 3. Curative occlusion* of the index aneurysm at 6 months post-treatment (* Raymond Roy Classification I and II) 4. Additional treatment on the index aneurysm within 6 months post-treatment (limited to surgical treatment including endovascular treatment, excluding medication) 5. Severe stroke** or neurological death attributable to treatment or device within 6 months of index treatment (** NIHSS 4 points or more deterioration that lasts for 24 hours or more) 6. All-cause mortality within 30 days and 6 months post-treatment 7. Death attributable to cranial nerves within 30 days and 6 months post-treatment 8. All strokes within 30 days and 6 months post-treatment 9. Stroke in the treated vascular territory within 30 days and 6 months post-treatment 10.Severe stroke in the treated vascular territory within 30 days and 6 months post-treatment 11.Adverse events and their causal relationship with the investigational device within 30 days and 6 months post-treatment 12.Device malfunctions | — |
