SYSTEMS AND METHODS FOR COMMUNICATION BETWEEN MEDICAL DEVICES
First Claim
1. A method of communicating with a medical device implanted within a patient comprising:
- receiving, at a medical device via electrodes connected to the patient, a conducted communication signal, wherein the conducted communication signal comprises a signal component and a noise component; and
adjusting, by the medical device, a receive threshold based at least in part on an amplitude of the received conducted communication signal,wherein adjusting the receive threshold at least partially reduces an amplitude of the noise component of the conducted communication signal.

Abstract
Systems and methods for conducted communication are described. In one embodiment, a method of communicating with a medical device implanted within a patient comprises receiving, at a medical device via electrodes connected to the patient, a conducted communication signal, wherein the conducted communication signal comprises a signal component and a noise component. The method may further comprise adjusting, by the medical device, a receive threshold based at least in part on an amplitude of the received conducted communication signal so as to reduce an amplitude of the noise component of the conducted communication signal.

17. A medical device comprising:
-
one or more electrodes; and a controller connected to the one or more electrodes, the controller configured to; receive a signal comprising a conducted communication signal communicated from an external medical device and noise signals via the one or more electrodes, and adjust the receive threshold based at least in part on an amplitude of the conducted communication signal and the noise signals to filter out noise signals from the received signal. - View Dependent Claims (18, 19)

20. A medical device comprising:
-
one or more electrodes; and a controller connected to the one or more electrodes, the controller configured to; receive a conducted communication signal via the one or more electrodes during a communication window; count a number of pulses of the conducted communication signal within the communication window and having an amplitude greater than a receive threshold; and if the pulse count reaches a pulse count threshold, increase the receive threshold and begin a new communication window.
