Seizure sensing and detection using an implantable device

Summary

NeuroPace's foundational patent covering the core architecture of the RNS System: an implantable device that continuously records intracranial EEG via electrodes placed at the seizure focus, applies detection algorithms to identify epileptiform activity, and automatically delivers brief bursts of electrical stimulation to normalize brain activity and abort seizures before they fully develop. The patent covers the closed-loop sensing, detection, and response cycle that defines responsive neurostimulation — a fundamentally different paradigm from open-loop DBS or VNS that stimulate on a fixed schedule regardless of brain state.
