SYSTEMS AND METHODS FOR AVOIDING NEURAL STIMULATION HABITUATION
First Claim
1. A method for delivering a vagal stimulation therapy to a vagus nerve, comprising:
- stimulating the vagus nerve, wherein stimulating the vagus nerve includes simultaneously stimulating both afferent axons and efferent axons in the vagus nerve; and
avoiding physiological habituation to stimulating the vagus nerve, wherein avoiding physiological habituation includes scheduling stimulation of the vagus nerve to provide a stimulation schedule using a programmable value for a therapy duration to control a therapy period or a programmable value for an intermittent neural stimulation parameter associated with on/off timing for stimulating the vagus nerve, wherein stimulating the vagus nerve includes stimulating the vagus nerve according to the stimulation schedule.

Abstract
An embodiment relates to a method for delivering a vagal stimulation therapy to a vagus nerve, including delivering a neural stimulation signal to non-selectively stimulate both afferent axons and efferent axons in the vagus nerve according to a predetermined schedule for the vagal stimulation therapy, and selecting a value for at least one parameter for the predetermined schedule for the vagal stimulation therapy to control the neural stimulation therapy to avoid physiological habituation to the vagal stimulation therapy. The parameter(s) include at least one parameter selected from the group of parameters consisting of a predetermined therapy duration parameter for a predetermined therapy period, and a predetermined intermittent neural stimulation parameter associated with on/off timing for the intermittent neural stimulation parameter.

16. A method for delivering a heart failure therapy in a patient with a vagus nerve, comprising:
-
stimulating the vagus nerve and avoiding physiological habituation to stimulating the vagus nerve, wherein stimulating the vagus nerve includes using a neural stimulation signal to simultaneously stimulate both afferent axons and efferent axons in the vagus nerve using a neural stimulation signal, the neural stimulation signal having a frequency of approximately 20 Hz, a pulse width of approximately 300 microseconds, and a duty cycle between 10% and 20% for a stimulation period of approximately 1 minute, and wherein avoiding physiological habituation includes scheduling stimulation of the vagus nerve for the heart failure therapy using a programmable value for a therapy duration to control a therapy period or a programmable value for an intermittent neural stimulation parameter associated with on/off timing for stimulating the vagus nerve. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
