SYSTEM AND METHODS TO GUIDE SCS USING SPECIFIC EVOKED POTENTIALS

Abstract: this document discusses a neurostimulation device. the neurostimulation device includes a stimulation circuit; a sensing circuit to sense evoked synaptic activity potential (esap) signals when coupled to the implantable lead, and a control circuit. the control circuit is configured to initiate delivery of neurostimulation energy by the stimulation circuit, initiate sensing by the sensing circuit of esap signals produced by the delivery of neurostimulation energy, change at least one parameter of the neurostimulation energy and continue the sensing of the esap signals, compare the sensed esap signals to a stored best sensed esap signal, wherein the best sensed esap signal was previously sensed at a recorded anatomical location using a different trial lead, and determine neurostimulation therapy parameters including a neurostimulation location to produce a best match esap signal at the recorded anatomical location that is a closest match to the stored best sensed esap signals.
