  • Publication number: 20160129259
    Abstract: Systems and methods are provided for delivering neurostimulation therapies to patients. A titration process is used to gradually increase the stimulation intensity to a desired therapeutic level. Between titration sessions one or more parameters, such as, for example, an acclimation interval, may be adjusted based on the patient's response to the stimulation. This personalized titration process can minimize the amount of time required to complete titration so as to begin delivery of the stimulation at therapeutically desirable levels.

  • Patent number: 9272143
    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.

  • Publication number: 20150297894
    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.

  • Publication number: 20150273214
    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.

  • Patent number: 9114262
    Abstract: An implantable device (11) for evaluating autonomic cardiovascular drive in a patient (10) suffering from chronic cardiac dysfunction is provided. A stimulation therapy lead (13) includes helical electrodes (14) configured to conform to an outer diameter of a cervical vagus nerve sheath, and a set of connector pins (28) electrically connected to the helical electrodes (14). A neurostimulator (12) includes an electrical receptacle (25) into which the connector pins (28) are securely and electrically coupled. The neurostimulator (12) also includes a pulse generator configured to therapeutically stimulate the vagus nerve through the helical electrodes (14) in alternating cycles of stimuli application and stimuli inhibition (90) that are tuned to both efferently activate the heart's intrinsic nervous system and afferently activate the patient's central reflexes by triggering bi-directional action potentials. The neurostimulator (12) includes a recordable memory (29) storing a baseline heart rate.

  • Publication number: 20150196762
    Abstract: A method for managing hypertension through renal nerve denervation and vagus nerve stimulation is provided. Renal nerves are disrupted to inhibit a sympathetic nervous system. Thereafter, 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. 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.

  • Publication number: 20150119959
    Abstract: A system for providing electrical stimulation of cervical vagus nerves for treatment of chronic cardiac dysfunction with bounded titration is provided. The system includes a patient-operable external controller to transmit a plurality of unique signals. The system further includes an implantable neurostimulator, which includes a pulse generator to deliver electrical therapeutic stimulation tuned to restore autonomic balance through continuously-cycling, intermittent and periodic electrical pulses that result in creation and propagation (in both afferent and efferent directions) of action potentials within the cervical vagus nerve of a patient through a pair of helical electrodes via an electrically coupled nerve stimulation therapy lead.

  • Publication number: 20150119956
    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: 20150073511
    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.

  • Publication number: 20150015417
    Abstract: An adherent patient device is configured to adhere to the skin of the patient and measure electrocardiogram data, impedance data, accelerometer data, blood oxygen data and temperature data. The adherent device can communicate wirelessly with gateways and a local processor system, such that the patient can wander about the hospital and update the monitoring station with the patient data when the patient is ambulatory. The local processor system can be configured to customize alerts for the patient, for example to notify automatically a specialist in response to a special condition of the patient. The adherent device may comprise a unique adherent device identifier such that the customized alert can be sent based on the unique device identifier. Each of the gateways can be carried and may comprise a unique gateway identifier, such that the unique device identifier and the unique gateway identifier can be used to locate the ambulatory patient.
