A spinal cord stimulator is an implanted device that sends low levels of electricity into the spinal cord to relieve pain. They consist of thin wires and a small pacemaker like battery pack. The electrodes are placed between the spinal cord and vertebrae 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 antenna are located outside of the body.
Spinal cord stimulators are most often used after nonsurgical pain treatment options have failed to provide sufficient relief.
