  • Patent number: 10905883
    Abstract: Methods and systems for selecting electrical stimulation parameters for an electrical stimulation device implanted in a patient can use an iterative process for identifying electrodes for stimulation, as well as suitable stimulation parameters. The process begins with an initial set of electrode combinations to identify regions of the nerve or other tissue for stimulation. This leads to selection of other electrode combinations to test, followed by the selection of multiple electrode groups (which can include three or more electrodes) for stimulation.

  • Publication number: 20200179692
    Abstract: Systems and methods for pacing cardiac conductive tissue are described. An exemplary system includes an electrostimulation circuit that may generate HBP pulses to stimulate patient physiologic conduction pathway, such as a His bundle or a bundle branch. The system includes an arrhythmia detector to detect an atrial tachyarrhythmia (AT) with intermittent ventricular conduction. A control circuit may sense ventricular activation and, in response to the detected AT indication, determine or update a His-bundle pacing (HBP) configuration. The HBP may be recursively updated on a beat-by-beat basis using the sensed ventricular activation. The electrostimulation circuit may deliver HBP according to the determined or adjusted HBP configuration to regularize ventricular rate during AT.

  • Publication number: 20200179705
    Abstract: Systems and methods for dynamically controlling HBP delivery based on patient AV conduction status are disclosed. An exemplary medical system includes an electrostimulation circuit to generate HBP pulses to stimulate a His bundle or a bundle branch of the heart. An AV conduction monitor circuit continuously or periodically assesses AV conduction status, and detects an indication of presence or absence of AV conduction abnormality. If an AV conduction abnormality is indicated, a control circuit may control the electrostimulation circuit to deliver the HBP pulses. Ventricular backup pacing may be delivered if HBP fails to capture and elicit ventricular activation. When the AV conduction become normal, the control circuit may withhold HBP delivery and promote patient intrinsic ventricular activation.

  • Patent number: 10603496
    Abstract: An apparatus comprises a stimulus circuit, a cardiac signal sensing circuit, and a control circuit. The cardiac signal sensing circuit senses a cardiac activity signal using a sensing channel. The stimulus circuit provides electrical pulse energy to a first pacing channel that includes a first left ventricular (LV) electrode and a second pacing channel that includes a second LV electrode. The control circuit initiates delivery of electrical pulse energy using the first and second pacing channels according to a first multi-site LV pacing mode; determines a cardiac event associated with a change in cardiac conduction path using a sensed cardiac activity signal; and changes to a second LV pacing mode in response to determining the cardiac event. The second LV pacing mode is different from the first multi-site LV pacing mode in one or more of a pacing site location and inter-electrode stimulus timing.
