Abstract: Embodiments described herein relate to implantable medical devices (IMDs) and methods for use therewith. Such a method includes, during each of a plurality of message alert periods during which a communication capability of the IMD is enabled, determining whether a valid message is detected. In response to determining that no valid message was detected during a message alert period, the communication capability of the IMD is temporarily disable for a disable period. A length of the disable period may be increased in response to no valid message being detected during two consecutive message alert periods. A length of the disable period may be dependent on an operational mode of the IMD, such that the length of the disable period differs for different operational modes. The IMD may also enter a noise state, and remain in the noise state until the IMD receives a specified number of valid messages.

Abstract: Implantable medical devices (IMDs) described herein, and methods for use therewith described herein, reduce how often an IMD accepts a false message and/or reduce adverse effects of an IMD accepting a false message. Such IMDs can be leadless pacemakers (LPs), or implantable cardio defibrillators (ICDs), but are not limited thereto. Such embodiments can be used help multiple IMDs (e.g., multiple LPs) implanted within a same patient maintain synchronous operation, such as synchronous multi-chamber pacing.

Abstract: Embodiments described herein relate to implantable medical devices (IMDs) and methods for use therewith. Such a method includes enabling a communication capability of an IMD during a message alert period and monitoring for a message while the communication capability is enabled during the message alert period. In response to receiving a message during the message alert period, there is a determination whether the message is valid or invalid. If the message is invalid, the message is ignored, and an invalid message count is incremented. A further message is monitored for during the message alert period occurs, when the invalid message count has not yet reached a corresponding invalid message count threshold. The communication capability of the IMD is disabled for a disable period, when the invalid message count reaches the corresponding invalid message count threshold. If a valid message is received, the IMD acts upon information included therein.

Abstract: In accordance with an embodiment, apparatuses and methods are provided for coordinating operation between leadless pacemakers (LPs) located in different chambers of the heart. A method includes configuring a local LP to receive communications from a remote LP through conductive communication over first and second channels, maintaining the first channel active for at least a portion of a time when the second channel is inactive to listen for event messages from the remote LP, detecting an incoming signal at the local LP over the first channel, determining whether the incoming signal received over the first channel corresponds to an LP wakeup notice, when the incoming signal corresponds to the LP wakeup notice, activating the second channel at the local LP, and receiving an event message over the second channel from the remote LP.

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.

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: Described herein is a fully-differential preamplifier comprising an input differential pair, an output current load, and a current source. The current source is coupled between the input differential pair and a low voltage rail and configured to control whether the fully-differential preamplifier is operating in a first mode or a second mode, wherein the preamplifier draws more current when operating in the second mode compared to when operating in the first mode. The input differential pair is coupled between the output current load and the current source. The output current load is coupled between a high voltage rail and the input differential pair. The input differential pair comprise positive and negative inputs of the fully-differential preamplifier. Nodes where the input differential pair and the output current load are coupled to one another comprise positive and negative outputs of the fully-differential preamplifier.

Abstract: Described herein is an implantable medical device (IMD) that wirelessly communicates another IMD, and methods for use therewith. Such a method can include receiving one or more implant-to-implant (i2i) communication signals from the other IMD using a communication receiver of the IMD, measuring a strength of at least one of the one or more received i2i communication signals or a surrogate thereof, and updating a strength metric based on the measured strength or surrogate thereof. The method further includes determining, based on the updated strength metric, whether to increase, decrease, or maintain the sensitivity of the communication receiver of the IMD, and responding accordingly such that the sensitivity is sometimes increased, sometimes decreased, and sometimes maintained. The method can also include selectively causing a transmitter of the IMD to transmit an i2i communication signal to the other IMD requesting that the other IMD adjust its transmission strength.

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.
