Heat transfer probe

A method comprising:

• transporting working fluid from a source through an inner channel of a probe to chance a temperature of tissue adjacent the probe;
• transporting the working fluid through a concentric outer channel of the probe back to the source;
• sensing a first temperature of the tissue at a first location using a first temperature sensor coupled to the probe;
• sensing a second temperature of the tissue at a second location using a second temperature sensor spaced apart from the first temperature sensor, the difference between the first and second temperatures being used to determine a thermal property of the tissue;
• comparing the first and second temperatures;
• and
• adjusting a flow rate of the working fluid based on the comparison.

A media comprising computer-executable instructions for:

• obtaining a first temperature of tissue sensed by a first temperature sensor coupled to a heat transfer probe;
• obtaining a second temperature of the tissue sensed by a second temperature sensor spaced apart from the first temperature sensor;
• comparing the first and second temperatures;
• calculating a thermal transport property of the tissue from the comparison of the first and second temperatures;
• and
• indicating a health of the tissue based on the thermal transport property.
