A neurostimulator is either an IPG (See Implantable pulse generator ) or is a small radio frequency system. Both of these systems are surgerical placed under the skin to send mild electrical impulses to the spinal cord or to the specific nerve that is causing pain. The electrical impulses are delivered through a lead (a special medical wire) that is also surgically placed. These electrical impulses block the signal of pain from reaching the brain.

A pacemaker-like device that is the power source for the system. It contains a small battery and computer chip programmed to send electrical pulses to control Parkinson's disease symptoms. It is implanted just under the skin in the upper chest area.

A device for electrical excitation of the central or peripheral nervous system.
