Responsive neurostimulation is a new approach to treating medically uncontrolled partial onset seizures. The RNS® System is the first device to provide responsive neurostimulation, automatically monitoring brain signals and providing stimulation to abnormal electrical brain events just when it is needed.
The system is approved by FDA as an adjunctive treatment for adults with medically refractory partial seizures that come from one or two seizure targets identified by your doctor. The RNS Neurostimulator is placed under the scalp and within the skull by a surgeon. One or two leads are then placed at the seizure target and connected to the neurostimulator. After the scalp heals, the neurostimulator should not be noticeable to others.
The neurostimulator continuously monitors the brain’s activity and is programmed by the epilepsy doctor to detect and record specific patterns that could lead to a seizure. When these patterns are detected, the neurostimulator responds with brief pulses of stimulation intended to disrupt the abnormal brain activity before a seizure occurs. Detection and stimulation settings are individualized for each patient’s patterns and so that stimulation is not felt.
In addition, each patient gets a take-home monitor so that brain activity data can be sent to the epilepsy doctor between office visits.
The RNS System is manufactured by NeuroPace, Inc. Additional information for patients and physicians is available at their website (http://www.NeuroPace.com).
