Terumo Neuro Microvention Woven EndoBridge (WEB) SL Aneurysm Intrasaccular Embolization System

he WEB™ Embolization System from Terumo Neurovascular (MicroVention) is an innovative intrasaccular flow disruptor designed for the endovascular treatment of wide-neck bifurcation intracranial aneurysms. Unlike traditional coiling techniques, the WEB™ device is deployed directly inside the aneurysm sac, creating immediate flow disruption and promoting progressive thrombosis while preserving the parent vessels. This unique single-device approach simplifies aneurysm management, reduces procedure time, and minimizes the need for adjunctive devices such as stents or balloons.

The WEB™ Embolization System is available in multiple configurations, including WEB™ SL (Single Layer), WEB™ SLS (Single Layer Sphere), and WEB™ SLS Jr, allowing customized sizing for a wide range of aneurysm morphologies. Featuring a self-expanding, braided nitinol mesh design, the WEB™ device offers excellent conformability and stable anchoring within the aneurysm. Backed by extensive clinical data and approved for use in both the United States and Europe, the WEB™ System represents a new generation of endovascular treatment for complex wide-neck aneurysms.

• GMDN Term Definition: A non-bioabsorbable, implantable device intended to induce a neurovascular thrombosis to treat an intracranial aneurysm and/or neurovascular arteriovenous malformation (AVM); it may also be intended to treat non-neurovascular malformations. It is in the form of a metal [e.g., platinum alloy] or metal/synthetic polymer wire which coils upon deployment within the aneurysm/vasculature; it is typically pre-attached to a nonimplantable delivery wire. Disposable devices associated with implantation (e.g., delivery wire, catheter) may be included.

MicroVention, part of Terumo Corporation, specializes in minimally invasive neurovascular technologies designed for the treatment of cerebrovascular conditions such as aneurysms, ischemic stroke, and arteriovenous malformations (AVMs). Their product portfolio includes embolization coils (HydroCoil and MicroPlex), flow diverters (FRED and FRED X), stent-assisted coiling systems (LVIS), neurovascular access devices (SOFIA and Headway microcatheters), and thrombectomy devices for acute ischemic stroke (ERIC). MicroVention’s solutions emphasize safety, precision, and clinical effectiveness, supporting neurointerventionalists in achieving optimal outcomes for patients undergoing complex neurovascular procedures.
