Brain Aneurysm

Brief summary

The study is an observational, European, multi-center, prospective assessment of the clinical utility of the 0.017 WEB Aneurysm Embolization System in subjects with intracranial aneurysms deemed appropriate for endovascular treatment.

Detailed description

All eligible subjects presenting to the participating Centers will be considered for entry into the study. Up to 160 evaluable subjects meeting the study entry criteria will be enrolled. Subjects will be followed per Institution's standard of care.

Interventions

Design outcomes

Primary

MeasureTime frameDescription
Aneurysm occlusion12 monthsAngiographic (conventional Angio) occlusion based on Raymond-Roy occlusion scale The Raymond-Roy occlusion classification (RROC) is an angiographic classification scheme for grading the occlusion of endovascularly treated intracranial aneurysms. * class I: complete obliteration * class II: residual neck * class III: residual aneurysm
Incidence of major stroke or neurological deaths12monthsThe proportion of subjects with death of any nonaccidental cause or any major stroke within the first 30 days after treatment or major ipsilateral stroke or death due to neurologic cause from day 31 to the 1 year after treatment
