Implantable neurostimulator-implemented method for enhancing heart failure patient awakening through vagus nerve stimulation
First Claim
1. A method for aiding awakening-induced tachyarrhythmias through vagus nerve stimulation, comprising the steps of:
- providing an implantable neurostimulator comprising a sensor and a pulse generator configured to deliver electrical therapeutic stimulation to a vagus nerve of a patient;
storing an operating mode of the pulse generator in a memory, the operating mode defining;
a first dose of the electrical therapeutic simulation comprising a first intensity; and
a second dose of the electrical therapeutic stimulation comprising a second intensity lower than the first intensity;
monitoring a physiological state of the patient to sense a patient'"'"'s awakening from a sleep state via the sensor; and
upon sensing the patient'"'"'s awakening, delivering the first dose to the vagus nerve.

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 that patient'"'"'s awakening, which activates the delivery of the enhanced dose.

17. A neurostimulator system for aiding awakening-induced tachyarrhythmias through vagus nerve stimulation, comprising:
-
a sensor; and a neurostimulator comprising a pulse generator configured to deliver electrical therapeutic stimulation to a patient'"'"'s vagus nerve and a memory comprising instructions that cause the pulse generator to; deliver a first dose of the electrical therapeutic stimulation at a first intensity; deliver a second dose of the electrical therapeutic stimulation at a second intensity lower than the first intensity; monitor the physiological state of the patient to sense a patient'"'"'s awakening from a sleep state via the sensor; and upon sensing the patient'"'"'s awakening, delivering the first dose to the vagus nerve. - View Dependent Claims (18, 19, 20)
