Abstract
Systems and methods for treating at least one of a plurality of disorders characterized at least in part by vagal activity. In embodiments, a method for treating obesity comprises positioning a first electrode on a vagus nerve of an obese patient at a location below a vagal innervation of the heart; treating the patient's obesity by applying an electrical treatment signal to the electrode with the electrical treatment signal having: a frequency selected for the signal to at least partially downregulate nerve impulses on the vagal nerve, wherein the signal has a frequency in excess of 200 Hz, and without simultaneously applying a neural impulse-inducing secondary electrical signal to the vagus nerve on a proximal side of the location whenever the electrical treatment signal is applied; and b) a plurality of on-times separated by a plurality of off-times, the signal applied during the on-times and not applied during the off-times, wherein the duration of the off-times is selected in response to a signal from a sensing electrode representing at least 50% of the activity of the vagal nerve as compared to baseline.
