What Is the DBS device?
The deep brain stimulation device consists of three components: • Lead. The lead (also called an electrode) is a thin, insulated wire that is inserted through a small opening in the skull and implanted in the brain. The tip of the lead is positioned within the targeted brain area. • Extension. The extension is an insulated wire that is passed under the skin of the head, neck, and shoulder, connectng the lead to the neurostimulator. • Neurostimulator. The neurostimulator (the “battery pack”) is the third component and is usually implanted under the skin near the collarbone. In some cases it may be implanted lower in the chest or under the skin over the abdomen. Once the system is in place, electrical impulses are sent from the neurostimulator up along the extension wire and the lead and into the brain. These impulses interfere with and block the electrical signals that cause Parkinson’s disease symptoms. The neurostimulator can be easily adjusted with a handheld device, as symptoms chan
