NeuroPace received FDA approval for its ECoG Assistant, an AI-driven feature for its epilepsy platform. The company's RNS System is a closed-loop implant that records cortical activity and delivers responsive stimulation. The new feature applies AI to the electrocorticography data the device already captures. The approval extends an established implant's value through software and positions NeuroPace within the broader move toward AI-assisted interpretation of long-term neural recordings.
