Abstract
A system comprising: at least one electrode adapted to be placed on a vagus nerve below a vagal innervation of the heart; an implantable controller comprising an induction coil, at least one circuit for generating a neural conduction blocking signal connected to the at least one electrode, a battery, and a central processing unit comprising program storage and memory; and an external programmer configured to: communicate at least one parameter for the neural conduction blocking signal to the implantable controller, wherein the parameter is selected for the neural conduction blocking signal to i) at least partially downregulate the vagus nerve, ii) allow at least partial recovery of the nerve activity following discontinuation of the neural conduction blocking signal, and iii) reduce pancreatic and biliary output via inhibition of pancreo-biliary output; and an external coil adapted to be worn by the patient, wherein the external coil is connected to the external programmer, and is adapted to inductively couple to the induction coil of the implantable controller.
