Biomedical device having a temperature sensing system
First Claim
1. A biomedical device having a temperature sensing system, comprising:
- a connector mounted in the biomedical device and including a plurality of connecting devices having first and second ends, the connecting devices conducting signals between respective first and second ends;
a first temperature sensor providing a first temperature signal mounted to the biomedical device having sensor leads connected to respective first ends of the connecting devices;
wherein the connection of a first temperature sensor lead to a first end of a connecting device creates a second temperature signal that combines with the first temperature signal to form a combined temperature signal, the connecting device conducting the combined temperature signal to its second end; and
a reference temperature sensor mounted at the connector to sense the temperature at the connector and to provide a temperature reference signal.

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.
