The temperature of the irrigating fluid exiting the probe differs from the temperature of the body cavity. Temperature readings of the irrigating fluid exiting the probe are recorded. A determination is made from the temperature readings that predetermined contact criteria between the probe and the interior wall of the body cavity are satisfied.1/l11 Ng o .
