The spinal cord stimulation system consists of several parts:
A battery-powered device called a pulse generator is implanted in the back or abdomen. It generates low-voltage electrical stimulation at the spinal cord through an insulated wire lead. The pulse generator never has to be replaced - just the batteries that power it.
A lead is implanted in the epidural space (next to the sac that surrounds the spinal cord) near the nerves that correspond to the patient's areas of pain.
An external programmer allows patients to fine-tune therapy within physician prescribed parameters to address changing pain relief needs.
Spinal cord stimulation involves a two part process:
Implantation of temporary spinal cord stimulator leads with trial period
Permanent implantation of a spinal cord stimulator generator, if successful trial
