About The WEB Aneurysm Embolization System
Building upon the foundation of endovascular embolic coils, the WEB is an intrasaccular flow disrupter designed to bridge the neck of a ruptured or unruptured intracranial aneurysm and to promote rapid, peri-procedural stasis. The WEB is based upon Sequent Medical's proprietary MicroBraidTM technology, a dense mesh constructed from a large number of extremely fine Nitinol wires. Unlike conventional medical braids, MicroBraid features a mix of wire diameters to achieve a tailored balance of compliance, porosity and profile across device sizes.

The WEB enables physicians to treat a broad range of intracranial aneurysms with the familiarity of an intrasaccular approach while using established biomaterials. The WEB product portfolio consists of the original WEB DL configuration, the second generation WEB SL and SLS configurations, and the recently introduced Enhanced Visualization (or EV) versions. To date, the WEB has been used to treat a wide variety of nearly 800 ruptured and unruptured aneurysms in Europe, Turkey, Latin America, Australia and New Zealand.
