The study is a prospective, multicenter single-arm cohort. Patients with wide neck bifurcation aneurysms (WNBAs) have few choices for safe and effective endovascular treatment. In this study, all patients with qualifying WNBAs will be treated with the WEB. The primary effectiveness outcome of the study is the likelihood of complete intracranial aneurysm occlusion on the 1 year angiogram as adjudicated by a core laboratory.

Primary purpose treatment
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.
