THE ADVANTAGE OF TIME,
THE POWER OF CONTROL^1-3

During presurgical embolization of bAVMs, with the Onyx^TM LES system, the DMSO solvent dissipates into the blood and interstitial fluids, causing the EVOH copolymer and suspended tantalum to precipitate in situ into a spongy, coherent substance. The Onyx™ liquid embolic system begins to form a skin and solidifies over time from the outside to the inside.
