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 that includes a plurality of communication pulses generated by a remote medical device; and
a noise component;
adjusting, by the medical device, a receive threshold based at least in part on an amplitude of the received conducted communication signal; and
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 conducted communication signal via the one or more electrodes, the conducted communication signal comprises; a signal component that includes a plurality of communication pulses in a pulse pattern communicated from an external medical device; and a noise component that includes noise signals; and determine if the received conducted communication signal comprises one or more pulses that do not match the pulse pattern of the communication pulses, and when so, adjust a receive threshold to further filter out the noise signals from the received conducted communication signal. - View Dependent Claims (18, 19)
