FDA Approves Two New Devices for Deep Brain Stimulation

The Food and Drug Administration (FDA) recently approved two new products from Medtronic. The Kinetra® Neurostimulator and Access® Therapy Controller will help to improve the delivery system for Deep Brain Stimulation (DBS), by simplifying the Activa® Therapy that is the heart of the operation. DBS is a surgical technique used to treat Parkinson’s symptoms by delivering an electrical current directly to selected brain cells.

The new system Kinetra® Neurostimulator uses only one device implanted in the chest to carry an electrical impulse to both sides of the brain and help control Parkinson’s symptoms. The previous system used two such devices. This improved version results in fewer incisions in surgery and will possibly reduce the time needed to conduct the procedure.

The Access® Therapy Controller is an advancement for both patients and doctors, as it allows patients to monitor battery life and have some control over the stimulation while at home via a hand-held device. This can lead to more effective and tailored therapy and less frequent battery changes and follow-up surgery.

Surgical treatment for Parkinson’s is usually an option for patients to explore after they have had experience with medications and are no longer satisfied with the results. A patient should discuss surgery thoroughly with his or her neurologist before making any decision.
