Patent attributes
Methods and an apparatus are described for treating at least one of a plurality of disorders of a patient characterized at least in part by vagal activity innervating at least one of a plurality of organs of the patient. Embodiments include a method for treating a patient having a gastro-intestinal disorder having a inflammatory basis, including positioning an electrode on a vagus nerve below a vagal innervation of a heart of the patient, and treating the patient's gastro-intestinal disorder by applying an electrical signal to the electrode, wherein the signal has a frequency of at least 500 Hz and is selected to down-regulate neural activity on the vagus nerve, allow partial restoration of nerve activity upon discontinuation of the electrical signal, and wherein the signal is configured to reduce pancreatic output and biliary output. An electrical signal is applied to the electrode to modulate vagal activity by an amount selected to treat the disorder. The signal may be blocking or a stimulation signal.
