Communications in a medical device system
First Claim
1. A method for communicating messages between a plurality of medical devices, wherein at least one of the plurality of medical devices is an implantable medical device, the method comprising:
- sensing cardiac electrical signals;
determining occurrences of intrinsic heartbeats;
providing a communication blanking period after each occurrence of an intrinsic heartbeat, wherein during each communication blanking period received communication messages are ignored; and
allowing communication of communication messages between a first medical device and a second medical device except during the communication blanking periods.

Abstract
Systems and methods for communicating between medical devices. In on example, a medical device comprises a communication module for communicating with an implantable leadless cardiac pacemaker through body tissue and a controller operatively coupled to the communications module. The controller may be configured to: identify intrinsic heartbeats; provide a blanking period after each occurrence of an intrinsic heartbeat; and communicate with the implantable leadless cardiac pacemaker via the communication module only during times between the blanking periods.
