WEB Aneurysm Embolization System
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.
