Temperature probe with dual sensors

Abstract

A temperature probe having dual temperature elements is connected to a cooling catheter controller to provide redundancy in temperature feedback to the controller, namely, to provide both a control temperature feedback signal and an alarm temperature feedback signal to the controller.

What is claimed is:  
     
         1 . A temperature sensing apparatus for insertion into a patient's body, comprising: 
 at least first and second temperature sensors supported by a probe body configured for advancing the sensors into the patient's body;    the probe body comprising a male or female telephone probe connector;    an interconnect cable having a female or male telephone cable connector selectively snappingly engageable with the probe connector;    at least one controller connector engageable with a controller of a closed circuit cooling catheter heat exchange system, the interconnect cable establishing electrical connectivity between the cable connector and the controller connector.    
     
     
         2 . The probe of  claim 1 , wherein the probe body is configured for advancement into the patient's esophagus.  
     
     
         3 . The probe of  claim 1 , wherein the probe body is configured for advancement into the patient's bladder.  
     
     
         4 . The probe of  claim 1 , wherein the probe body is configured for advancement into the patient's blood vessel.  
     
     
         5 . A temperature probe for insertion into a patient's body comprising: 
 an elongated probe body, the probe body being configured for advancing the probe body into a patient's body;    at least first and second temperature sensors located on the probe body generating respective first and second temperature signals, wherein the second signal is in electrical communication with an alarm.
