Device and method to selectively and reversibly modulate a nervous system structure to inhibit the perception of pain

A system for modulating targeted neural and non-neural tissue of a nervous system structure to treat a medical condition of a patient, the system comprising:

• an electrical stimulation device comprising an electrode sized and configured to be placed in contact with a mucosal tissue of the patient, the electrode configured to deliver a transmucosal electrical stimulation to a treatment site proximate the targeted neural and non-neural tissue of the nervous system structure underlying the mucosal tissue;
• and
• a controller configured to connect to the electrode of the electrical stimulation device and to a power source configured to supply electrical energy to the electrode, wherein the controller is configured to direct operation of the electrical stimulation device to apply the transmucosal electrical stimulation to the treatment site through the electrode,
• wherein the controller is configured to direct operation of the electrical stimulation device to apply the transmucosal electrical stimulation to the treatment site to selectively modulate the targeted neural and non-neural tissue of the nervous system structure to reversibly inhibit the perception of pain and preserve other sensory and motor function, and proprioception,
• wherein the controller is configured to direct operation of the electrical stimulation device to apply the transmucosal electrical stimulation to the treatment site as a pulse duty cycle selected to not damage the mucosal tissue and to not damage the targeted neural and non-neural tissue.
