The FDA has approved Micro Therapeutic‘s minimally invasive therapy for arterio-venous malformations (AVM) in the brain, the Onyx liquid embolic glue:
As a result of high blood flow and pressure imbalances, AVMs in the brain are at risk of hemorrhage, or rupture, which can lead to stroke, severe disability and even death. Treatment options for AVMs include catheter-based therapies, surgery, radiation therapy, or a combination of these treatments. Catheter-based treatments involve the delivery of embolic materials to occlude, or block, the abnormal blood vessels comprising the AVM.
Onyx is a liquid embolic material that is delivered by neurovascular specialists through MTI’s proprietary micro catheters directly into a vascular defect, such as a brain aneurysm or AVM, in a very controlled manner. After delivery of the embolic material, the liquid quickly transforms into a solid polymer cast, thereby sealing off the vessels in the AVM from blood flow and reducing the risk of rupture. In the United States, Onyx is indicated for use in the pre-surgical embolization of brain AVMs. Endovascular embolization can reduce the size and vascularity of the AVM, thereby facilitating safer and easier surgical resection.
