How It Works

Medtronic DBS Therapy uses an implanted medical device, similar to a pacemaker, to send mild electrical signals to an area of the brain that controls movement. As a result, DBS Therapy blocks some of the brain messages that cause the movement symptoms associated with Parkinson’s disease.

The Medtronic DBS Therapy System

The Medtronic DBS Therapy System has three parts. The system is placed in the body by a neurosurgeon.

• Neurostimulator: The power source for the system, containing a battery and a computer chip programmed to send electrical signals to control the movement-related symptoms of Parkinson's disease. A neurostimulator is small (for example, one model is 2.4 by 2.4 by 0.4 inches) and is implanted in the chest, just below the collarbone.
• Lead (pronounced "leed"): A set of thin, coated wires that that carries the electrical signal to the brain tissue
• Extension: An insulated wire placed under the scalp that connects the lead and neurostimulator

Programmers

A specialist uses a wireless device to program the implanted system to best control your symptoms. Also, you will have a small hand-held controller that allows you to turn the system on and off and, in some cases, adjust your own stimulation settings within a range set by your doctor.
