Any neurostimulation system has a spinal cord stimulator. The spinal cord stimulation device is the basic component; it is implanted in either the abdominal or buttock area by your doctor. Leads are then run from it to the epidural space in the spinal canal.
A rechargeable implantable pulse generator (IPG) type of stimulator is shown here. The rechargeable IPG is an example of the latest technology in spinal cord stimulation devices (and systems). Patients and doctors like the new IPG technology because the devices are usually small, which gives some flexibility as to where they can be implanted. Other types of devices, which use older technologies, are also still on the market.
