Intra-body device communication with redundant message transmission
First Claim
1. An implantable medical device (IMD) configured to pace a patient'"'"'s heart, the IMD disposable within a chamber of the patient'"'"'s heart, the IMD comprising:
- a housing;
a plurality of electrodes;
a controller housed by the housing and operably coupled to the plurality of electrodes, the controller configured to;
generate and deliver pacing pulses via a pair of the plurality of electrodes;
receive messages transmitted by conducted communication via a pair of the plurality of electrodes;
receive cardiac signals via a pair of the plurality of electrodes; and
the controller is configured to successfully receive a plurality of transmissions of the same message transmitted by conducted communication during a cardiac cycle, and when more than one of the plurality of transmissions of the same message are successfully received by the controller during the cardiac cycle, the controller is configured to treat the more than one successfully received transmissions of the same message as a single copy of the message, thereby ignoring the additional successfully received one or more copies of the same message.

Abstract
Implantable medical devices (IMD), such as but not limited to leadless cardiac pacemakers (LCP), subcutaneous implantable cardioverter defibrillators (SICD), transvenous implantable cardioverter defibrillators, neuro-stimulators (NS), implantable monitors (IM), may be configured to communicate with each other. In some cases, a first IMD may transmit instructions to a second IMD. In order to improve the chances of a successfully received transmission, the first IMD may transmit the instructions several times during a particular time frame, such as during a single heartbeat. If the second IMD receives the message more than once, the second IMD recognizes that the messages were redundant and acts accordingly.
