Deep Brain Stimulation (DBS) Helps You Take Control of Your Symptoms

The Activa™ System is easy to turn ON or OFF with a control magnet. To turn it ON, grasp the magnet with the flat end away from you, as shown. Press the flat end of the magnet directly over and along the length of the pulse generator. Hold the magnet steady for two seconds. Then move the magnet away to turn the generator ON.

To turn the Activa™ System OFF, simply repeat the procedure. Keep the magnet away from the pulse generator when you are not using it. Also keep it away from credit cards or any other media including video and cassette tapes, computer disks, VCRs, televisions and cameras.

A small instruction card with complete directions and precautions will be given to you after the system is programmed.

Suggestions and Precautions

You can use household appliances, computers, and cellular phones with the Activa™ System ON.

It is also safe for you to pass through metal detectors in airports. Your pulse generator may set them off, so always carry your identification card. You may want to request assistance to bypass the detectors.

Approach theft control devices in stores with caution. They may cause you to feel uncomfortable stimulation. Walk up to within a few feet of the theft detector. If you don’t feel anything unusual, walk directly through the theft detector area, keeping to the middle between the two pillars.

Avoid the following tests and equipment:

  • Magnetic resonance imaging (MRI)
  • Ultrasound, or diathermy (heat ultrasound treatments)
  • Electrocautery
  • Diathermy (deep heat therapy)

Tell your family physician and dentist that you have an implanted device. If you need a special medical test, be sure to tell the clinician about the system. Do not have medical tests without first checking with your doctor.
