Onyx® HD-500 Liquid Embolic Agent for Wide-Neck Aneurysms

The Onyx HD-500 liquid embolic system is another tool for treating wide-neck intracranial aneurysms. Liquid Onyx is delivered into the aneurysm by a controlled injection through a micro catheter. Onyx is a polymer that solidifies within five minutes, thereby occluding the aneurysm.
