Leadless cardiac pacemaker system with conductive communication

摘要

A cardiac pacing system comprises multiple leadless cardiac pacemakers configured for implantation in electrical contact with a cardiac chamber and configured for multi-chamber cardiac pacing. The individual leadless cardiac pacemakers comprise at least two leadless electrodes configured for delivering cardiac pacing pulses, sensing evoked and/or natural cardiac electrical signals, and communicating bidirectionally among the leadless cardiac pacemaker plurality.

1. A cardiac pacing system comprising:
a plurality of leadless cardiac pacemakers individually configured for implantation in electrical contact with a cardiac chamber and configured in combination for multi-chamber cardiac pacing, the leadless cardiac pacemaker plurality individually comprising at least two leadless pacing electrodes and a controller operatively connected to the electrodes and configured to deliver cardiac pacing pulses through the electrodes, sense evoked and/or natural cardiac electrical signals through the electrodes, and bidirectionally communicate information through the electrodes for coordinating pacing among the plurality of leadless cardiac pacemakers.
