Onyx® Liquid Embolic System
The Advantage of Time, the Power of Control
Liquid embolic products are used to treat both aneurysms (weakened balloon-like portions of a vessel) and arterio-venous malformations (the abnormal growing together of arteries and veins forming a web-like mass). The embolic material is injected in a liquid form through a small micro-catheter into the effected area of the brain, where it begins to solidify, reducing the pressure and likelihood of rupture. Unlike other liquid embolics on the market, ev3’s Onyx material is non-adhesive and provides a more controlled delivery and set up.
