Spinal cord stimulators consist of thin wires (the electrodes) and a small, pacemaker-like battery pack (the generator). The electrodes are placed between the spinal cord and the vertebrae (the epidural space), and the generator is placed under the skin, usually near the buttocks or abdomen. Spinal cord stimulators allow patients to send the electrical impulses using a remote control when they feel pain. Both the remote control and its antenna are outside the body.
