Abstract: System and methods for energy adaptive communications between medical devices are disclosed. In one example, a medical device includes a communication module configured to deliver a plurality of pulses to tissue of a patient, where each pulse has an amount of energy. A control module operatively coupled to the communication module, may be configured to, for each delivered pulse, determine whether the delivered pulse produces an unwanted stimulation of the patient and to change the amount of energy of the plurality of pulses over time so as to identify an amount of energy that corresponds to an unwanted stimulation threshold for the pulses. The control module may then set a maximum energy value for communication pulses that is below the unwanted stimulation threshold, and may deliver communication pulses below the maximum energy value during communication with another medical device.
