Treatment of Dural Arteriovenous Fistulas With SQUID™ Liquid Embolic Agent

"SQUID™ is injected into the vascular site to be treated, under fluoroscopic control. DMSO dissipates in the blood and causes precipitation of EVOH in which the tantalum powder is trapped. It then forms a consistent spongy embolus.~This embolus solidifies from the outside inwardly while moving distally in the vessel. The non-adhesive character of the embolus allows slow and controlled injections while leaving in place the microcatheter."
