FDA Approves New Deep Brain Stimulation Device
Posted by Maggie McGuire, June 16, 2015
The U.S. Food and Drug Administration (FDA) announced Friday that it had approved another deep brain stimulation (DBS) device for treatment of Parkinson’s disease and essential tremor.
The Brio Neurostimulation System from St. Jude Medical works in a similar way as the available DBS device: Medtronic’s Activa Deep Brain Stimulation Therapy System, approved in 1997 for tremor and in 2002 for Parkinson’s disease.
In DBS, a neurosurgeon implants a thin electrode into the brain, targeting motor and potentially other circuits that are not functioning properly. Small electrical pulses from a device similar to a cardiac pacemaker modulate the signals that cause some of the Parkinson’s motor symptoms. While a powerful treatment for many people living with Parkinson’s, this therapy does not treat all symptoms and isn’t suitable for all patients.
