摘要： Described herein are methods, devices, and systems that enable a remote non-implantable device (RNID) to send commands to a leadless pacemaker (LP) implanted within a patient. The RNID provide commands to a local non-implantable device (LNID) over one or more communication networks, and the LNID sends the commands to a second implantable device (SID) by transmitting radio frequency (RF) communication signals, which include the commands, using an antenna of the LNID. After receiving the commands from the LNID, by receiving RF communication signals that include the commands using an antenna of the SID, the SID transmits conductive communication signals, which include the commands, using electrodes of the SID. The LP receives the commands from the SID by receiving the conductive communication signals, which include the commands, using electrodes of the LP, and the LP performs command responses based on the commands that originated from the RNID.

摘要： In accordance with an embodiment, a system and method is provided for providing communications between first and second implantable medical devices (IMDs). The system comprises a first implantable medical device (IMD) configured to transmit a first event message during or preceding a first cardiac cycle, and a second IMD configured to receive the first event message, wherein receipt of the first event message configures the second IMD to generate pacing pulses for only a predetermined number (“n”) of consecutive cardiac cycles, wherein n is an integer equal to or greater than 2. The method comprises transmitting a first event message during or preceding a first cardiac cycle from the first IMD, receiving the first event message at the second IMD, in response to receiving the first event message, arming the second IMD to generate a pacing pulse for a second cardiac cycle, and arming the second IMD to generate a pacing pulse for only a predetermined number of consecutive cardiac cycles immediately subsequent to the second cardiac cycle.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
