Onyx™ Liquid Embolic System
Designed to provide complete filling and distal penetration, Onyx™ liquid embolic system (LES) is a pre-mixed, radiopaque, injectable embolic fluid made of EVOH (ethylene vinyl-alcohol copolymer), DMSO (dimethyl-sulfoxide) and TA (micronized tantalum powder).

Overview
The Onyx™ confidence - performance you can trust1
During embolization with the Onyx™ 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.
Durable2
Flexible Onyx™ cast creates a durable embolization for neurovascular lesions.
Control2
Cohesive behavior provides a controlled and time-flexible, distal or nidal Onyx™ LES injection.
Visibility2
Provides live feedback of the embolic fill and trajectory, enabling visibility of Onyx™ LES injection under fluoroscopy.
Onyx™LES is available in several viscosities
The numerical term of Onyx™ LES describes its relative viscosity:
- Onyx™18: liquid embolic system for maximum penetration
- Onyx™34: liquid embolic system for high-flow occlusion
Delivering Onyx™ LES Flow directed catheters
The Marathon™ and Apollo™ flow directed catheter have been expressly designed to complement and enhance embolization with Onyx™. These synergistic tools help you journey to more tortuous locations, embolize more challenging lesions and return with confidence.
