System selection

Neurostimulation systems typically have a programmable control unit with an internal battery plus a lead (or wire), which are both put in place during an operation. There are two types of neurostimulation systems:

  • A non-rechargeable system that requires replacement when the battery becomes exhausted. Typically this happens after 3–5 years depending on battery consumption i.e. the amount of power you need of power to control your pain
  • A system with a rechargeable battery and battery life up that could last beween 5 to 10 years, depending on the type of system

The battery is usually placed under the skin of the abdomen, where it is most comfortable and least visible, although your doctor will position it in the best place for you. Your doctor or nurse will adjust your system so that it effectively treats your pain. This is done externally via radio signals through the skin.
Your neurostimulation system also comes with a patient programmer. This is simple hand-held device, similar in size and shape to a computer mouse.  It allows you to change or control your own stimulation to suit your changing needs, within limits set by your doctor.  For example, you may need more or less stimulation depending on whether you are standing up or sitting down. You can also use this programmer to turn your neurostimulator on and off.
The battery life of your neurostimulator depends on how much you use the system and the intensity of stimulation (the electrical pulses). When it is time to have your battery replaced, your doctor will remove the device during a minor operation and replace it with a new one.
This involves no overnight stay or general anaesthetic.
