System and method for gastric electrical stimulation using compound nerve action potential feedback

A gastric electric stimulation system, comprising:

• a processing system having a processor;
• and
• at least one of a left vagus nerve sensor and a right vagus nerve sensor coupled to the processing system;
• the processing system configured to:
• receive a model which statistically correlates sensed compound nerve action potential (CNAP) parameters measured from at least one of left and right vagus nerves of subjects within a population to feedback surveys of the subjects in the population corresponding to a plurality of gastric symptoms and symptom parameters,
• receive one or more gastric symptoms of a subject outside of the population (Subjectout),
• from the model determine CNAP parameters that correspond to the gastric symptoms with least severity (CNAPmin),
• measure CNAP activity of the Subjectout from the at least one of left and right vagus nerve sensors while modifying gastric electrical stimulation (GES) parameters for the Subjectout from a plurality of predetermined GES parameters,
• select the GES parameters from the plurality of predetermined GES parameters that corresponds to the CNAPmin (GESout), and
• output the GESout.
