Classification: CPC A  H | IPC A  H

Claim 18:
19. A system, comprising:
an implantable leadless pacemaker (LP); and
an external device that is incapable of programming the LP;
the LP including a pulse generator, two or more implantable electrodes, and a controller, the pulse generator of the LP configured to selectively produce conductive communication pulses, the two or more implantable electrodes of the LP coupled to the pulse generator of the LP and used to output the conductive communication pulses produced by the pulse generator; and
the external device including or communicatively coupled to two or more external electrodes used to receive conductive communication pulses from the LP;
the controller of the LP configured to
monitor 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;
periodically cause an advertisement sequence of the conductive communication pulses to be produced by the pulse generator, so that the advertisement sequence is output using at least two of the two or more implantable electrodes, irrespective of whether the controller has detected the presence of at least one said notification condition; and
monitor for a programmer acknowledgement sequence of pulses within a programmer acknowledgement monitor window following each outputting by the LP of the advertisement sequence of pulses, to thereby enable the LP to determine whether an external programmer is attempting to establish a communication session with the LP;
monitor for an external device acknowledgement sequence of pulses within an external device acknowledgement monitor window; and
cause a notification sequence of the conductive communication pulses to be produced by the pulse generator of the LP within one or more notification transmission windows following the advertisement sequence of pulses being output, so that the notification sequence is output using at least two of the two or more implantable electrodes of the LP, in response to the controller of the LP recognizing the presence of at least one said notification condition and detecting the external device acknowledgement sequence of pulses within the external device acknowledgement monitor window;
wherein the notification sequence of pulses is encoded with diagnostic information associated with the LP and/or associated with the patient within which the LP is implanted.
