Abstract
A system for monitoring temperature comprising a first thermocouple temperature sensor mounted to a catheter, the catheter also having a connector with a plurality of connecting devices for making the thermocouple signals available to external equipment. The connecting devices are formed of a material dissimilar to at least one of the thermocouple leads such that a second thermocouple is created at the connection point. The second thermocouple produces a second temperature signal that combines with the signal from the first thermocouple. A reference temperature sensor is mounted at the connector to sense the temperature at the connector and provide a reference temperature signal for use by a processor in correcting the combined temperature signal to derive the first thermocouple signal received from the connector.
