A neurostimulator creates the electrical pulses that control some of the movement symptoms of essential tremor on one side of the body.
A very thin wire called a lead delivers electrical signals from the neurostimulator to the brain.
A doctor will use a programming device to adjust the settings.
The patient may have a device, similar to a remote control, which allows to turn the system on and off and check the battery. Patients may also be able to adjust the stimulation within options programmed by the doctor.
The Medtronic DBS system will include either a ActivaTM PC, Activa SC, or Activa RC neurostimulator. The neurostimulator delivers stimulation to one side of the brain through one wire to control symptoms of essential tremor.
The doctor will recommend the right Medtronic neurostimulator for the patient's needs. The battery in an Activa PC or Activa SC device does not need to be recharged. The neurostimulator lasts 3 to 5 years on average, depending on the programmed settings. The Activa RC neurostimulator has a rechargeable battery that allows to keep the same device for 15 years between replacements. Recharge the battery regularly with an external recharger.
The neurostimulator stores important data about itself and the programmed settings that have worked for the patient in the past. This means the patient doesn't need to carry such records if travelling or switch clinics.
The patient will have a device, similar to a remote control, which allows them to turn the DBS system on and off and to check the battery. They may also be able to adjust the stimulation within options programmed by the doctor. The patient programmer will alert about 3 months before the battery runs out, so patients have plenty of time to plan for replacement.
We know it’s important that the patient has access to MRI if they need this important test to diagnose a medical condition or injury. We offer the first full-body MR Conditional* DBS systems to have scans anywhere on the body with some Medtronic DBS devices under certain conditions.
Medtronic DBS systems are MR Conditional which means they are safe for MRI scans under certain conditions. If the conditions are not met, the MRI could cause tissue heating especially at the implanted lead(s) in the brain which may result in serious and permanent injury or death. Before having an MRI, always talk with the doctor who manages your DBS Therapy to determine your eligibility and discuss potential benefits and risks of MRI.
