  • Patent number: 9999773
    Abstract: Multi-modal stimulation therapy may be utilized in which two or more stimulation therapies having different stimulation parameters may be delivered to a single patient. This can preferentially stimulate different nerve fiber types and drive different functional responses in the target organs. The stimulation parameters that may vary between the different stimulation therapies include, for example, pulse frequency, pulse width, pulse amplitude, and duty cycle.

  • Publication number: 20180126170
    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. The implanted stimulation device includes a physiological sensor for recording the patient's response to the neurostimulation therapy on an ambulatory basis over extended periods of time.

  • Publication number: 20180116541
    Abstract: The present invention includes systems and methods for measuring, monitoring and treating arrhythmia and cardiac function via the intrinsic cardiac nervous system. The systems and methods compare neural signatures of the intrinsic cardiac nervous system that are associated with both healthy and diseased myocardial tissue to identify and target afferent intrinsic cardiac neurons for which signaling has been affected by diseased cardiac tissue. Accordingly, methods of modulating afferent neural signals from the diseased myocardium to the intrinsic cardiac nervous system, intrathoracic extracardiac ganglia, and higher centers of the cardiac neuraxis are used as a novel therapeutic approach to mitigating ischemic heart disease.

  • Publication number: 20180117333
    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. The implanted stimulation device includes a physiological sensor for monitoring the patient's response to the neurostimulation therapy on an ambulatory basis over extended periods of time and a control system for adjusting stimulation parameters to maintain stimulation in the neural fulcrum zone based on detected changes in the physiological response to stimulation.

  • Patent number: 9950169
    Abstract: Systems and methods are provided for delivering neurostimulation therapies to patients for treating chronic heart failure. A computer-implemented control system is operated to automatically identify a neural fulcrum zone based on a monitored patient physiological response. Ongoing neurostimulation therapy is delivered within the neural fulcrum zone.

  • 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: 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.
