Liquid coolant supply system

A liquid coolant containment unit for use with a thermal therapy catheter, the containment unit comprising:

• a coolant-sensor interface module including:
• a body having a fluid chamber with an inlet port and an outlet port for allowing a liquid coolant to circulate through the fluid chamber;
• a temperature interface supported adjacent the fluid chamber within the body, wherein the temperature interface communicates a temperature indicant of the liquid coolant circulating through the fluid chamber to a temperature sensor;
• and
• a pressure interface supported adjacent the fluid chamber within the body, wherein the pressure interface communicates a pressure indicant of the liquid coolant circulating through the fluid chamber to a pressure sensor;
• and
• a liquid coupling assembly for fluidly connecting the coolant-sensor interface module to input and output ports of the thermal therapy catheter and for containing the liquid coolant as the liquid coolant is cooled and pumped by cooling and pumping means.

A liquid coolant supply system for supplying a liquid coolant to a thermal therapy catheter, the system comprising:

• a sensor control unit including:
• a temperature sensor;
• a pressure sensor;
• a peristaltic pump, wherein the pump pumps the coolant at a rate based upon sensed pressure signals from the pressure sensor;
• and
• a cooling plate, wherein the cooling plate has a temperature which varies based upon sensed signals from the infrared sensor;
• and
• liquid coolant containment unit including:
• a liquid reservoir configured for being removably supported adjacent the cooling plate, wherein the reservoir contains and channels the liquid coolant adjacent the cooling plate to cool the liquid coolant;
• a coolant-sensor interface module including:
• a body having a fluid chamber with an inlet port and an outlet port for allowing the liquid coolant to circulate through the fluid chamber;
• a temperature interface supported adjacent the fluid chamber within the body, wherein the temperature interface communicates a temperature indicant of the liquid coolant circulating through the fluid chamber to the temperature sensor;
