Abstract:
A system and method for controlling non-paresthesia stimulation of neural tissue of a patient. The method delivers a non-paresthesia stimulation waveform, senses sensory action potential (SAP) signals from the neural tissue of interest, and analyzes the SAP signals to obtain SAP activity data for at least one of an SAP C-fiber component or an SAP A-delta fiber component. The method determines whether the SAP activity data satisfies a criteria of interest and adjusts at least one of the therapy parameters to change the non-paresthesia stimulation waveform when the SAP activity data does not satisfy the criteria of interest.

Claim (Index 1):
A method to treat chronic pain in a patient by controlling non-paresthesia stimulation of neural tissue of a dorsal root ganglion of the patient, the method comprising:\n providing a lead having at least one electrode on the lead configured to be implanted at a target position proximate to neural tissue of the dorsal root ganglion of the patient; delivering a non-paresthesia stimulation waveform to the at least one electrode based on a therapy parameter set (TPS), the stimulation waveform including a series of pulses configured to excite at least one of A-delta fibers or C-fibers of the neural tissue of the dorsal root ganglion of the patient; sensing sensory action potential (SAP) signals; iteratively repeating the delivering and sensing operations while changing at least one parameter from the TPS; applying a reference input during an interval between successive burst waveforms of the non-paresthesia stimulation waveform, the reference input creating the SAP signals sensed; analyzing the SAP signals to obtain SAP activity data associated with the TPS for at least one of an SAP C-fiber component or an SAP A-delta fiber component, the analyzing operations obtaining a collection of SAP activity data associated with multiple therapy parameter set; selecting one or more parameters for the TPS based on the collection of SAP activity data; programming an implantable pulse generator to deliver stimulation to neural tissue of the dorsal root ganglion according to the TPS; and activating the implantable pulse generator to deliver electrical stimulation to the patient according to the programmed TPS.
