  • Patent number: 12023504
    Abstract: Methods, devices and program products are provided for managing a pacing therapy using an implantable medical device (IMD). The methods, devices and program products sense cardiac activity (CA) signals at electrodes located proximate to multiple left ventricular (LV) sites and a right ventricular (RV) site of the heart and utilizing one or more processors to measure activation times between the multiple LV sites and the RV site based on the CA signals. The processors program an order of activation for the multiple LV sites based on the activation times and identify an RV activation time and a septum activation time based on the CA signals. The processors calculate a septum to RV activation time (SRAT) based on the RV and septum activation times and program an AVSRAT delay based on the SRAT.

  • Publication number: 20240181265
    Abstract: Described herein are methods for use with an implantable system including at least an atrial leadless pacemaker (aLP). Also described herein are specific implementations of an aLP, as well as implantable systems including an aLP. In certain embodiments, the aLP senses a signal from which cardiac activity associated with a ventricular chamber can be detected by the aLP itself based on feature(s) of the sensed signal. The aLP monitors the sensed signal for an intrinsic or paced ventricular activation within a ventricular event monitor window. In response to the aLP detecting an intrinsic or paced ventricular activation itself from the sensed signal within the ventricular event monitor window, the aLP resets an atrial escape interval timer that is used by the aLP to time delivery of an atrial pacing pulse if an intrinsic atrial activation is not detected within an atrial escape interval.

  • Publication number: 20240180484
    Abstract: Implantable systems, and methods for use therewith, monitor a patient's arterial blood pressure without requiring an intravascular pressure transducer. A plurality of calibrations factors are stored, each of which is associated with a respective one of a plurality of different postures, activity levels, or HR ranges, or different combinations thereof. A signal indicative of activity of the patient's heart, and a signal indicative of changes in arterial blood volume of the patient are obtained, and a pulse arrival time (PAT) value is determined. A current posture, activity level, and/or HR of the patient is/are determined and used to identify stored calibration factor(s) that correspond thereto. Values indicative of the patient's arterial blood pressure is/are determined based on the PAT value and the stored calibration factor(s) identified based on the patient's current posture, activity level, and/or HR. Such value(s) and/or changes thereto can be used to trigger and/or adjust therapy.

  • Patent number: 12000448
    Abstract: A biostimulator transport system, such as a biostimulator retrieval system, having a torque limiter to allow a torque shaft to slip rotationally relative to a handle, is described. The torque limiter can connect the torque shaft to the handle, and can include a slip mechanism, such as a flat spring or apposed clutch faces, that allow the torque shaft to slip relative to the handle when a resistance torque at a distal end of the torque shaft exceeds a torque threshold. Accordingly, torque can be applied to a biostimulator by the torque shaft with a reduced likelihood of over-torqueing the biostimulator within the target tissue. Other embodiments are also described and claimed.
