  • Publication number: 20190275329
    Abstract: Systems and methods for pacing cardiac conductive tissue are described. A medical system includes an electrostimulation circuit to generate His-bundle pacing (HBP) pulses. A sensing circuit senses a physiologic signal, and detect a local His-bundle activation discrete from a pacing artifact of the HBP pulse. A control circuit verifies capture status in response to the HBP pulses. Based on the capture status, the control circuit determines one or more pacing thresholds including a selective HBP threshold representing a threshold strength to capture only the His bundle but not the local myocardium, and a non-selective HBP threshold representing a threshold strength to capture both the His bundle and the local myocardium. The electrostimulation circuit may deliver HBP pulses based on the selective and non-selective HBP thresholds.

  • Patent number: 10391319
    Abstract: An implantable medical device (IMD) includes a housing that is configured to be positioned at least in part in a chamber of a heart, and in some cases, in a right ventricle (RV) proximate an RV facing side of the ventricular septum of the heart. When so provided, an RV electrode may be fixed relative to the housing to be proximate the RV facing side of the ventricular septum. An LV electrode may be spaced a distance from the RV electrode and the housing such that the LV electrode is positioned at least partially within the ventricular septum. An LV electrode position adjustment assembly may be used to adjust the depth at which the LV electrode is positioned within the ventricular septum.

  • Patent number: 10391317
    Abstract: Systems, devices, and methods for pacing a heart of a patient are disclosed. In some embodiments, a method for pacing a patient's heart may include determining a posture of the patient and determining if the determined posture corresponds to a predetermined sleep posture. If the determined posture correspond to the predetermined sleep posture, the method may further comprise determining a respiration phase of the patient and pacing the patient's heart at a pacing rate that is modulated based on the determined respiration phase of the patient. If the determined posture does not correspond to the predetermined sleep posture, the method may pace the patient's heart at a pacing rate that is not dependent on the respiration phase of the patient.

  • Patent number: 10350423
    Abstract: A device configured to deliver and deploy an implantable medical device (IMD) includes a handle assembly and a shaft extending distally therefrom. A device containment housing configured to accommodate the IMD is coupled to the distal region of the shaft. At least one of the shaft and device containment housing includes a compressible region that is configured to compress by an amount that is related to an applied force. The device may include a first position indicator and a second position indicator. An applied force causes the compressible region to compress by an amount that is related to the applied force, causing a change in distance between the first position indicator and the second position indicator and thus providing an indication of the applied force.

  • Publication number: 20190201696
    Abstract: A ventricular implantable medical device that is configured to detect an atrial timing fiducial from the ventricle. The ventricular implantable medical is configured to deliver a ventricular pacing therapy to the ventricle based on the detected atrial timing fiducial. If the ventricular implantable medical device temporarily fails to detect atrial activity because of noise, posture, patient activity or for any other reason, an atrial implantable medical device may be configured to communicate atrial events to the ventricular implantable medical device and the ventricular implantable medical device may synchronize the ventricular pacing therapy with the atrium activity based on those communications.

  • Publication number: 20190201698
    Abstract: Systems and methods for cardiac pacing are described in this document. A medical system includes an electrostimulation circuit to generate His-bundle pacing (HBP) pulses to capture a His bundle, and LV pacing (LVP) pulses to capture a left ventricle. A sensing circuit may sense a cardiac activity, such as an atrial or an LV cardiac electrical activity. The system includes a control circuit controlling the delivery of HBP and LVP pulses. The HBP and LVP may be delivered concurrently or sequentially. In an example, the LVP pulses may be delivered based on a His-bundle capture status in response to the HBP pulse. The system may adjust one or more His-bundle stimulation parameters based on the His-bundle capture status.
