  • Patent number: 9919157
    Abstract: A method for managing bradycardia through vagus nerve stimulation is provided. An implantable neurostimulator configured to deliver electrical therapeutic stimulation in both afferent and efferent directions of a patient's cervical vagus nerve is provided. An operating mode is stored, which includes parametrically defining a maintenance dose of the electrical therapeutic stimulation tuned to restore cardiac autonomic balance through continuously-cycling, intermittent and periodic electrical pulses. The maintenance dose is delivered via a pulse generator through a pair of helical electrodes via an electrically coupled nerve stimulation therapy lead independent of cardiac cycle. The patient's physiology is monitored, and upon sensing a condition indicative of bradycardia, the delivery of the maintenance dose is suspended.

  • Publication number: 20180001091
    Abstract: An implantable neurostimulator-implemented method for managing tachyarrhythmias 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 of a patient's cervical vagus nerve. Operating modes of the pulse generator are stored. A maintenance dose of the electrical therapeutic stimulation is delivered to the vagus nerve via the pulse generator to restore cardiac autonomic balance through continuously-cycling, intermittent and periodic electrical pulses. A restorative dose of the electrical therapeutic stimulation is delivered to prevent initiation of or disrupt tachyarrhythmia through periodic electrical pulses delivered at higher intensity than the maintenance dose.

  • Publication number: 20170354823
    Abstract: A method of neurostimulation titration. The method includes setting titration parameters for an electrical signal delivered by an implantable medical device, initiating titration with the titration parameters and an aggressiveness profile, performing titration by increasing at least one of a current amplitude, a frequency, a pulse width or a duty cycle of the electrical signal until a threshold is reached or a side effect is detected, pausing the titration while waiting for commands from the patient or caregiver, and resuming the titration in response to receiving authorization from an external device.

  • Publication number: 20170319854
    Abstract: Systems and methods are provided for delivering neurostimulation therapies to patients for treating chronic heart failure. A neural fulcrum zone is identified and ongoing neurostimulation therapy is delivered within the neural fulcrum zone. This neural fulcrum zone corresponds to a combination of stimulation parameters at which autonomic engagement is achieved, while the tachycardia-inducing stimulation effects are offset by the bradycardia-inducing effects, thereby minimizing side effects such as significant heart rate changes while providing a therapeutic level of stimulation.

  • Publication number: 20170296817
    Abstract: A patient suffering from congestive heart failure is at increased risk of cardiac arrhythmogenesis during sleep, particularly if experiencing central sleep apnea as a co-morbidity. Low intensity peripheral neurostimulation therapies that target imbalance of the autonomic nervous system have been shown to improve clinical outcomes. Thus, bi-directional autonomic regulation therapy is delivered to the cervical vagus nerve at an intensity that is insufficient to elicit pathological or acute physiological side effects and without the requirement of an enabling physiological feature or triggering physiological marker. The patient's physiology is monitored to identify periods of sleep. In one embodiment, upon sensing a condition indicative of tachyarrhythmia following a period of bradycardia, as naturally occurs during sleep, an enhanced “boost” dose of bi-directional neural stimulation intended to “break” the tachyarrhythmic condition is delivered.

  • Publication number: 20170296822
    Abstract: An implantable neurostimulator-implemented method for enhancing post-exercise recovery through vagus nerve stimulation is provided. An implantable neurostimulator, including 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 including a patient's cervical vagus nerve. An operating mode is stored in the pulse generator. An enhanced dose of the electrical therapeutic stimulation is parametrically defined and tuned to prevent or disrupt tachyarrhythmia through continuously-cycling, intermittent and periodic electrical pulses. The patient's physiological state is monitored during physical exercise via at least one sensor included in the implantable neurostimulator, and upon sensing a condition indicative of cessation of the physical exercise, the enhanced dose is delivered for a period of time the enhanced dose to the vagus nerve.

  • Publication number: 20170296824
    Abstract: Systems and methods are provided for delivering neurostimulation therapies to patients for treating chronic heart failure. A neural fulcrum zone is identified and ongoing neurostimulation therapy is delivered within the neural fulcrum zone. This neural fulcrum zone may be identified by monitoring a patient's response to incrementally increased intensity settings at a first frequency. If the incremental intensity increases do not result in the identification of the neural fulcrum zone, the frequency may be changed to provide finer resolution identification of the neural fulcrum zone.
