Implantable neurostimulator-implemented method for enhancing heart failure patient awakening through vagus nerve stimulation
First Claim
1. An implantable neurostimulator-implemented method for aiding awakening-induced tachyarrhythmias through vagus nerve stimulation, comprising the steps of:
- providing an implantable neurostimulator comprising a pulse generator configured to deliver electrical therapeutic stimulation in a manner that results in creation and propagation in both afferent and efferent directions of action potentials within neuronal fibers of a patient'"'"'s cervical vagus nerve;
storing an operating mode of the pulse generator in a recordable memory, the storing comprising;
parametrically defining an enhanced dose of the electrical therapeutic stimulation tuned to prevent initiation of or disrupt tachyarrhythmia, wherein the enhanced dose comprises continuously-cycling, intermittent and periodic electrical pulses; and
parametrically defining a maintenance dose of the electrical therapeutic stimulation tuned to restore cardiac autonomic balance, wherein the maintenance dose comprises continuously-cycling, intermittent and periodic electrical pulses delivered at a lower intensity than the enhanced dose; and
monitoring a patient'"'"'s physiological state to sense a patient'"'"'s awakening from a sleep state via at least one sensor of the implantable neurostimulator, and upon sensing the patient'"'"'s awakening from the sleep state, delivering for a period of time the enhanced dose to the vagus nerve via the pulse generator through helical electrodes electrically coupled to the pulse generator via a nerve stimulation therapy lead.

Abstract
An implantable neurostimulator-implemented method for managing tachyarrhythmias upon a patient'"'"'s awakening from sleep through vagus nerve stimulation is provided. An implantable neurostimulator, including a pulse generator, is configured to deliver electrical therapeutic stimulation in a manner that results in creation and propagation (in both afferent and efferent directions) of action potentials within neuronal fibers comprising the cervical vagus nerve of a patient. Operating modes of the pulse generator are stored. An enhanced dose of the electrical therapeutic stimulation is parametrically defined and tuned to prevent initiation of or disrupt tachyarrhythmia upon the patient'"'"'s awakening from a sleep state through at least one of continuously-cycling, intermittent and periodic ON-OFF cycles of electrical pulses. Other operating modes, including a maintenance dose and a restorative dose are defined. The patient'"'"'s physiological state is monitored via at least one sensor to detect the patient'"'"'s awakening, which activates the delivery of the enhanced dose.
