  • Patent number: 9533153
    Abstract: Systems and methods are provided for delivering neurostimulation therapies to patients for treating chronic heart failure. A titration process is used to gradually increase the stimulation intensity to a desired therapeutic level. This 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: 9511228
    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.

  • Patent number: 9504836
    Abstract: Various aspects relate to a method. In various embodiments, a therapy of a first therapy type is delivered, and it is identified whether a therapy of a second therapy type is present to affect the therapy of the first therapy type. Delivery of the therapy is controlled based on the presence of the therapy of the second therapy type. Some embodiments deliver the therapy of the first type using one set of parameters in the presence of a therapy of a second type, and deliver the therapy of the first type using another set of parameters when the therapy of the second type is not present. In various embodiments, one of the therapy types includes a cardiac rhythm management therapy, and the other includes a neural stimulation therapy. Other aspects and embodiments are provided herein.

  • Patent number: 9504832
    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.

  • Publication number: 20160339252
    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: 20160325099
    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.

  • Patent number: 9445719
    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.
