WEB Aneurysm Embolization Device
The WEB is an intra-aneurysmal device intended for use in endovascular embolization of intracranial aneurysms. The intended therapeutic effect of the WEB device is to line the neck of the aneurysm with a metallic structure that disrupts the inflow of blood, causing hemostasis within the aneurysm sac, and leading to thrombus formation within the implant. |
Device: WEB
The WEB is an intra-aneurysmal device intended for use in endovascular embolization of intracranial aneurysms.

- The Primary Safety Endpoint Included Any Death or Major Stroke in the First 30 Days and Neurologic Death or Ipsilateral Major Stroke Between Day 31 and Day 365. [ Time Frame: 12 months ]The study's primary safety endpoint was the proportion of subjects with death of any nonaccidental cause or any major stroke (defined as an ischemic or hemorrhagic stroke resulting in an increase of 4 points or more on the National Institutes of Health Stroke Scale (NIHSS)) within the first 30 days after treatment or major ipsilateral stroke or death due to neurologic cause from day 31 to 365 days after treatment.
- Percentage of Subjects With Complete Aneurysm Occlusion Assessed Using the WEB Occlusion Scale (WOS) Without Retreatment, Recurrent Subarachnoid Hemorrhage, Without Significant Parent Artery Stenosis (>50% Stenosis) at One Year After Treatment [ Time Frame: 12 months ]The primary effectiveness endpoint was defined as the percentage of subjects with complete aneurysm occlusion assessed using the WEB Occlusion Scale (WOS) without retreatment, recurrent subarachnoid hemorrhage, without significant parent artery stenosis (>50% stenosis) at one year after treatment in the mITT population.
