Cleveland Clinic-backed Autonomic Technologies raises $20 million

MENLO PARK, California — InterWest Partners invested $20 million into Autonomic Technologies, a California-based neurostimulation company launched through innovations from the Cleveland Clinic’s Neurological Institute.

Autonomic is creating a small, implantable medical device to treat severe headaches, according to a news release from InterWest. It was created in 2007 through research by Clinic neurologist Dr. Ali Rezai, who remains on the company’s board. Chris Coburn, executive director of Cleveland Clinic Innovations, is also on the Autonomic board. The Clinic is a previous investor in the company along with Kleiner Perkins Caufield & Byers.

The release didn’t say how Autonomic would use the Series B funding and the company declined to list revenue on its filing with the Securities and Exchange Commission. Autonomic raised $5 million in 2008. (Hat tip Venturebeat)
