How it works
“The RNS® System (NeuroPace, Mountain View, CA) provides responsive cortical stimulation via a cranially implanted programmable neurostimulator connected to 1 or 2 recording and stimulating depth or subdural cortical strip leads that are surgically placed in the brain according to the seizure focus. The neurostimulator continually senses electrocorticographic activity and is programmed by the physician to detect abnormal electrocorticographic activity and then provide stimulation. The physician adjusts detection and stimulation parameters for each patient to optimize control of seizures.” The source article by Morrell includes information on its effectiveness.
Brief notes on the neurostimulator, cortical strip leads, depth leads, remote monitor, want, magnet, programmer, want, and patient data management system (PDMS) for the NeuroPace RNS can be found here.
NeuroPace RNS user manuals for patients and physicians are available here.
The NeuroPace RNS is intended for patients who have been diagnosed as having no more than 2 seizure foci, have not responded to two or more anti-epileptic medications, and are currently having frequent, disabling seizures. Here is the source.
