Abstract: An intra vascular temperature management catheter incudes a shaft through which working fluid can circulate to and from a proximal location on the shaft. The catheter extends from a connector hub. At least one heat exchange member is supported by a distal part of the shaft or other part of the catheter to receive circulating working fluid from the proximal location. A temperature sensor is supported on the catheter for generating a temperature signal representative of blood temperature to a control system. The temperature sensor includes first and second conductive leads having respective first and second distal segments on or in the catheter shaft. The first and second distal segments are arranged to be in thermal contact with blood flowing past the catheter when the catheter is disposed in a blood vessel of a patient. Also, the temperature sensor includes a joining body connected to proximal segments of the first and second leads. The joining body may be supported in the hub or in another location proximal to the first and second conductive leads.
