Onyx™ Liquid embolic system

Designed for presurgical embolization of brain arteriovenous malformations (bAVMs), Onyx™ liquid embolic system (LES) is a pre-mixed, radiopaque, injectable embolic fluid consisting of the following components: EVOH (ethylene vinyl-alcohol copolymer), DMSO (dimethyl-sulfoxide) and Ta (micronized tantalum powder).

Alert Indications, Safety and Warnings

Overview

The advantage of time,
The power of control^1-3

During presurgical embolization of bAVMs, with the Onyx™ LES, 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.

Product details

Visibility

Suspended micronized tantalum powder provides contrast visualization under fluoroscopy

Durability

Onyx™ cast reduces blood loss during neurosurgical removal of AVM

Control

Its cohesive deposition and delivery¹provide a slow controlled Onyx™ injection, with the ability to stop when needed

Onyx™ LES is available in several formulations with varying flow properties

The numerical term of Onyx™ LES describes its relative viscosity. Onyx™ LES is offered in 18 and 34 to provide options for controllable injections³.

Onyx^™ LES compatible microcatheters

The Apollo™ Onyx™ delivery microcatheter was expressly designed to access the neuro vasculature for the controlled selective infusion of the Onyx™ liquid embolic system (LES).⁴

The Marathon™ Flow Directed microcatheter is intended to access the peripheral and neuro vasculature for the controlled selective infusion of physician-specified therapeutic agents such as embolization materials and of diagnostic materials such as contrast media.⁵
