A medical device includes an elongate shaft extending along a shaft longitudinal axis and includes a shaft proximal portion and a shaft distal portion. The medical device can include an electrode disposed on the shaft distal portion. The medical device can include a first conductor lead and a second conductor lead, each of the conductor leads electrically being coupled to the electrode. A thermocouple junction formed via a thermocouple conductor can be electrically coupled to the electrode and the first conductor lead.
