Neurostimulators

In brain stimulation a neurostimulator, also called an implanted pulse generator (IPG) is a battery powered device designed to deliver electrical stimulation to the brain, central and peripheral nervous system.

Applications and use
Neurostimulators are an integral component of surgically implanted systems used in such procedures as deep brain stimulation, spinal cord stimulation and vagus nerve stimulation, designed to treat neurological disorders and neuropathic pain..

These devices are implanted within a person's body, usually beneath the clavicle. The neurostimulator can be calibrated by a neurologist, nurse or trained technician to the individual patient's needs.

Neurostimulators must be replaced periodically upon battery failure, (usually within three to five years) though battery life is dependent on individual usage. Battery life can be reasonably predicted by the use of a telemetry programming device so that the unit can be replaced prior to battery failure. Rechargeable devices are now commonly implanted with a battery life in the range of 15 to 20 years dependent on use.
