![]() The battery is recharged by an external device worn for a few hours every two to three weeks. Rechargeable Implantable Pulse Generator (IPG) consists of a rechargeable battery and control electronics. ![]() ![]() When the battery wears out, it is surgically replaced. Conventional Implantable Pulse Generator (IPG) consists of a battery and control electronics.People with SCS should avoid areas and performing tasks which are linked with strong electromagnetic interference, examples incluide electricity substations and activities such as arc welding. Other medical scans such as ultrasound, CT and plain x-ray can be performed. Patients with SCS units are not able to have MRI procedures due to heating of the implanted electrodes which can cause spinal cord damage. If the patient has at least 50% improvement in pain during the trial, the patient is considered a candidate for the permanent unit. A temporary percutaneous lead is used and is connected to an external pulse generator. Ī trial is usually done before the permanent unit is placed. The possibility of lead migration is lessened when placed by laminectomy. Surgical ProcedureĬomplications are generally related to the surgical procedure and can include lead migration, infection, epidural hematoma, paralysis, dural tap, and in extremely rare cases, death. Randomized controlled trials have shown efficacy of spinal cord stimulator in failed-back syndrome. Studies since then have demonstrated efficacy of SCS in relieving select chronic pain disorders including failed back syndrome, complex regional pain syndrome and peripheral neuropathy. First report of a spinal cord stimulator implantation was in 1967 by Shealy.
