A retrieval docking component includes a base and a limiting part. A distal end of the base along an axial direction is configured for connection with a body of an implantable medical device, and a proximal end of the base along an axial direction is connected to the limiting part. A radial outer dimension of the limiting part is greater than a radial outer dimension of the proximal end of the base. The limiting part includes at least two accommodation grooves along its circumference, which are open outwardly in radial direction of the limiting part and configured for capture a snare of a delivery device. The structure of the retrieval docking component provides adequate and reasonable accommodation space to the retrieval snare in a limited space, enabling the delivery device conveniently and reliably form a connection with the retrieval docking component, increasing success rate of retrieval and docking.

A dual-chamber leadless pacemaker (LP) system includes a first leadless pacemaker (LP1) and a second leadless pacemaker (LP2), wherein LP1 is configured to be implanted in or on a first heart chamber and deliver pacing pulses to the first heart chamber, and LP2 is configured to be implanted in or on a second heart chamber and deliver pacing pulses to the second heart chamber. Information is obtained regarding the amplitude of the pacing pulses delivered by LP2 to the second heart chamber and / or the sensitivity of a sensing circuit of LP1, which is configured to be used by LP1 to detect the inherent depolarization of the first heart chamber. A crosstalk protection duration is determined based on at least some of this information, such that it is performed for an appropriate duration when crosstalk protection is executed.

A device includes a signal generator module, a processing module, and a housing. The signal generator module is configured to deliver pacing pulses to an atrium. The processing module is configured to detect a ventricular activation event and determine a length of an interval between the ventricular activation event and a previous atrial event that preceded the ventricular activation event. The processing module is further configured to schedule a time at which to deliver a pacing pulse to the atrium based on the length of the interval and control the signal generator module to deliver the pacing pulse at the scheduled time. The housing is configured for implantation within the atrium. The housing encloses the stimulation generator and the processing module.
