Following a successful trial, a specialist will insert the permanent device in an out-patient procedure (lasting 30-90 minutes), sometimes with sedation or general anesthesia. In a numbed area, the electrode lead is surgically implanted into the epidural space in the spine. Then, the generator or receiver is connected to the electrode lead and is surgically implanted nearby, usually in the upper buttock/back, upper chest wall, or abdominal wall area. During the procedure, the patient may be awakened for pain level feedback so that small adjustments can be made to ensure the stimulation is targeting the areas where pain is transmitted to provide optimal pain relief. Following the implantation, patients learn to use the handheld stimulator controller that turns the energy level up and down similar to a television remote controller to adjust the stimulation level.
