Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Provides controlled delivery of a nonadhesive liquid embolic that forms a cohesive cast within the target. Typical contexts include arteriovenous malformations, endoleaks, and other complex embolization procedures requiring slow, deliberate injection.
What most clearly distinguishes it from similar devices?
Key distinctions
Onyx™ is nonadhesive and forms a cohesive cast during controlled injection, distinguishing it from rapidly polymerizing adhesive agents such as n-BCA.
