Like a heart pacemaker, the devise is implanted in the chest; leads then send electrical impulses to the brain. To date the pacemaker has already been approved to treat disorders such as Parkinson's disease.
The technique known as deep brain stimulation has helped some of the most severely depressed patients, as well as patients with OCD with no serious side effects related to the device.
Currently Medtronic has an application before the U.S. Food and Drug administration for the device to be used for treating OCD. An implantable device, by Cyberonics, was approved by the FDA in 2005 for treatment-resistant depression, by sending signals to the brain through the vagus nerve in the neck.
