    Abstract: Certain embodiments of the present technology disclosed herein relate to implantable systems, and methods for use therewith, that use a temperature sensor to initially detect an onset of patient activity, and then use a motion sensor to confirm or reject the initial detection of the onset of patient activity. Other embodiments of the present technology disclosed herein relate to implantable systems, and methods for use therewith, that use a motion sensor to initially detect an onset of patient activity, and then use a temperature sensor to confirm or reject the initial detection of the onset of patient activity. The use of both a motion sensor and a temperature sensor provides improvements over using just one of the types of sensors for rate responsive pacing.

    Abstract: Methods and systems for terminating a pacemaker mediated tachycardia (PMT) are described herein. During a period that a PMT is not detected, an implantable system delivers an atrial pacing pulse to an atrial cardiac chamber in response to a PA interval expiring without an intrinsic atrial event being detected during the PA interval. The systems performs atrial sensing to thereby monitor for intrinsic atrial events in the atrial cardiac chamber, performs ventricular sensing to thereby monitor for intrinsic ventricular events in a ventricular cardiac chamber, and detects the PMT. Additionally, the system, in response to the PMT being detected, initiates a PMT PA interval that is shorter than the PA interval that the system would otherwise use for atrial pacing if the PMT was not detected.

    Abstract: Described herein are methods, devices, and systems that estimate a total amount of time it takes to discharge a battery of an IMD from initial to subsequent capacity levels, which total amount of time is indicative of a longevity of the IMD. In certain embodiments, a range of capacity levels for the battery is separated into N separate intervals. For each of the N intervals, an estimate of an amount of time it takes for the battery to discharge from a beginning to an end of the interval is determined, to thereby determine N amounts of time that are summed to estimate the total amount of time that it takes to discharge the battery from the initial to subsequent capacity levels. In other embodiments, an iterative equation is used to estimate the total amount of time takes it takes to discharge the battery from the initial to subsequent capacity levels.

    Abstract: Described herein are methods, devices, and systems for providing an implantable leadless pacemaker (LP) with a remote follow-up capability whereby the LP can provide diagnostic information to an external device that is incapable of programming the LP, wherein the LP includes two or more implantable electrodes used to output both pacing pulses and conductive communication pulses. Such a method can include the LP monitoring for a presence of one or more notification conditions associated with the LP and/or associated with a patient within which the LP is implanted, and the LP periodically outputting an advertisement sequence of pulses, using at least implantable electrodes of the LP, irrespective of whether the LP recognizes the presence of at least one notification condition. The method can also include the LP recognizing the presence of at least one notification condition, and based thereon, the LP also outputting a notification sequence of pulses.

    Abstract: The present disclosure provides systems and methods for classifying signals of interest in a cardiac rhythm management (CRM) device. A CRM device includes an intrinsic activation sensing circuit configured to pass signals falling within a first passband, a crosstalk sensing circuit configured to pass signals falling within a second passband, wherein the second passband contains higher frequencies than the first passband, and a computing device communicatively coupled to the intrinsic activation sensing circuit and the crosstalk sensing circuit, the computing device configured to classify a signal of interest as one of an intrinsic activation signal and a crosstalk signal based on whether the signal of interest is passed by the intrinsic activation sensing circuit and the crosstalk sensing circuit.

    Abstract: A leadless pacemaker (LP) is configured to be implanted in or on a cardiac chamber. The LP includes a first housing made of an electrically conductive material, a second housing made of an electrically conductive material, and an inter-housing insulator between the first and second housings and electrically isolating the first and second housings from one another. Electronic circuitry within the first housing includes pulse generator(s), sense amplifier(s), and a controller. A battery within the second housing provides power to the electronic circuitry via conductors that electrically couple poles of the battery to the electronic circuitry within the first housing. The LP includes two or more electrodes including at least one tip electrode and at least one ring electrode. At least two of the electrodes are selectively couplable to a pulse generator to enable delivery of pacing pulses to the cardiac chamber in or on which the LP is implanted.
