The Activa DBS System uses Medtronic's DBS technology.
The Activa System includes three components, which are implanted completely inside the body:
- Neurostimulator – A pacemaker-like device that is the power source for the system. It contains a small battery and a computer chip programmed to send electrical pulses to control symptoms.
- DBS™ Lead – An insulated wire with four electrodes that is implanted in the brain.
- Extension – An insulated wire placed under the scalp that connects to the lead and runs behind the ear, down the neck, and into the chest below the collarbone where it connects to the neurostimulator. For children, the neurostimulator may be implanted in the abdomen.
The system is programmed to your individual needs using two external components:
- A portable programmer that your doctor or nurse uses to set the parameters of the neurostimulator.
- A hand-held programmer that you or your caregiver may be provided with in order to turn the neurostimulator on or off. However, in most cases the neurostimulator is always on.
