What are the components of the Deep Brain Stimulation? What does each one do?
The Deep Brain Stimulation system consists of three implanted components:(1) Neurostimulator: A device containing a battery and microelectronic circuitry. It is implanted under the skin near the collarbone, and generates electrical signals that are delivered through the extension and lead to the targeted structures deep within the brain. With dimension similar to a stopwatch 6cm wide (width), 5 1/2am tall (height) and 1 cm thick (depth) the neurostimulator weights about 42 grams, or just under 1 ounces.(2) Extension: An insulated wire that is passed under the skin of the head, neck, and shoulder to connect the lead to the implanted neurostimulator(3) DBS lead: A thin, insulated coiled wire with four electrodes at the end. Using MRI scan and stereotactic equipment, the neurosurgeon positions the electrode of the lead in the sub thalamic nucleus and anchors the lead to the skull.External components of the system include a physician programmer; patient therapy controller.The Physician Pro
