Selectively raising or lowering the temperature of certain organs

Finkle

I was thinking the other day on whether there are any medical procedures that involve raising or lowering the temperature of a solitary organ. I know controlled temperature changes are mostly safe and useful for certain conditions. It seems that this could be useful for doing it to one particular organ where doing it to the entire body could be otherwise dangerous. This seems to be an extreme measure to take but is it plausible? Is there anything that this could possibly treat?
