US 2026/0224903 A1 · REDUCING COMMUNICATION BURDEN BETWEEN LEADLESS PACEMAKERS

Abstract

Described herein is a multi-chamber implantable LP system comprising at least a first LP configured to be implanted in or on a first cardiac chamber, and a second LP configured to be implanted in or on a second cardiac chamber. For each cardiac event, of a plurality of cardiac events associated with the first cardiac chamber, the first LP is configured to determine for the cardiac event whether at least one of a plurality of predetermined conditions is satisfied. Additionally, the first LP is configured to abstain from transmitting a cardiac event message indicative of the cardiac event to the second LP, or transmit the cardiac event message indicative of the cardiac event to the second LP, based on whether there is a determination that at least one of the plurality of predetermined conditions is satisfied. Methods for use with such a multi-chamber implantable LP system are also described herein.

Dependent claims

A multi-chamber implantable leadless pacemaker (LP) system, comprising:

a first LP configured to be implanted in or on a first cardiac chamber and configured to store information defining a plurality of predetermined conditions;
and
a second LP configured to be implanted in or on a second cardiac chamber;
wherein for each cardiac event that is nonconcurrent with blanking and refractory periods of the first LP, of a plurality of cardiac events associated with the first cardiac chamber that are nonconcurrent with the blanking and refractory periods of the first LP, the first LP is configured to
determine for the cardiac event whether at least one of the plurality of predetermined conditions is satisfied;
and
abstain from transmitting a cardiac event message indicative of the cardiac event to the second LP, or transmit the cardiac event message indicative of the cardiac event to the second LP, based on whether there is a determination that at least one of the plurality of predetermined conditions is satisfied.

A method for reducing communication burden in a multi-chamber implantable leadless pacemaker (LP) system comprising a first LP configured to be implanted in or on a first cardiac chamber and a second LP configured to be implanted in or on a second cardiac chamber, the method comprising:

the first LP storing information defining a plurality of predetermined conditions;
the first LP determining, for each cardiac event that is nonconcurrent with the blanking and refractory periods of the first LP of a plurality of cardiac events associated with the first cardiac chamber that are nonconcurrent with the blanking and refractory periods of the first LP, whether at least one of the plurality of predetermined conditions is satisfied;
and
the first LP selectively abstaining from transmitting a cardiac event message indicative of the cardiac event that is nonconcurrent with the blanking and refractory periods of the first LP to the second LP, or transmitting the cardiac event message indicative of the cardiac event that is nonconcurrent with the blanking and refractory periods of the first LP to the second LP, based on whether there is a determination for the cardiac event that at least one of the plurality of predetermined conditions is satisfied.
