Activa SC Neurostimulator Deep Brain Stimulation for Dystonia


Activa SC

Our Medtronic deep brain stimulation (DBS) system for dystonia* has technology and features that will make a difference for you now and into the future. Your doctor will recommend the right device for your needs. Learn about the Activa™ SC neurostimulator, which can deliver stimulation to one side of the brain through a lead (thin wire). Two stimulators may be used to stimulate areas on both sides of the brain.


The battery does not need to be recharged. The neurostimulator lasts 3 to 5 years on average, depending on the programmed settings.


Your doctor will program your system for your needs.   


You will have a device, similar to a remote control, which allows you to turn the system on and off and to check the battery. You may also be able to adjust the stimulation within options programmed by your doctor. The patient programmer will alert you about 3 months before the battery runs out, so you have plenty of time to plan for replacement.   


The neurostimulator stores important data about itself and the programmed settings that have worked for you in the past. This means you don’t need to carry such records if you travel or switch clinics. A doctor can access the information in your neurostimulator with a clinician programmer. 


Medtronic provides the first safe access to MRI anywhere on the body with some DBS systems under certain conditions—giving your doctor an important tool for diagnosis. 


Humanitarian Device - Authorized by Federal Law as an aid in the management of chronic, intractable (drug refractory) primary dystonia, including generalized and/or segmental dystonia, hemidystonia, and cervical dystonia (torticollis), in patients seven years of age or above. The effectiveness of the devices for treating these conditions has not been demonstrated.

Medtronic DBS systems are MR Conditional which means they are safe for MRI scans only 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.
