Micro Therapeutics

Micro Therapeutics, Inc. was a pioneering medical device company specializing in the development of minimally invasive technologies for the treatment of neurovascular and peripheral vascular diseases. The company's flagship product, the Onyx Liquid Embolic System, revolutionized the treatment of brain arteriovenous malformations (bAVMs) by providing a non-adhesive, liquid embolic agent that allows for controlled delivery and deep penetration into vascular lesions. Beyond embolics, the company offered a comprehensive suite of access products, including the SilverSpeed guidewires and Rebar microcatheters, designed to navigate the complex vasculature of the brain. Founded in 1993 and headquartered in Irvine, California, Micro Therapeutics became a leader in the interventional neuroradiology market. The company was acquired by ev3 Inc. in 2006, and its technology now forms a core component of Medtronic's neurovascular portfolio.
