Claim Text:
1. A method of detecting a thermocouple short circuit in a medical device, comprising: providing a medical device having a plurality of electrodes and at least two thermocouples coupled to each electrode; delivering energy to each of the plurality of electrodes; obtaining a first temperature measurement from a first thermocouple of the at least two thermocouples of each electrode; obtaining a second temperature measurement from the first thermocouple of the at least two thermocouples of each electrode; obtaining a third temperature measurement from a second thermocouple of the at least two thermocouples of each electrode; comparing the third temperature measurement to a predefined temperature threshold; calculating a rate of change over time between the first and second temperature measurements; comparing the calculated rate of change over time to a predefined rate of change over time threshold; and generating an indication of a thermocouple short circuit when the calculated rate of change over time exceeds the predefined rate of change over time threshold, the indication of a thermocouple short circuit being generated based at least in part on a result of the comparison of the third temperature to the predetermined threshold.
