A treatment system includes a fluid cooling supply system for chilling and delivering liquid coolant to a patient. The fluid cooling supply system includes a cooling device and a heat exchanger device. The heat exchanger device is biased to the cooling device and is in fluid communication with a treatment device in a patient. The fluid cooling supply system includes at least one biasing mechanism to provide a given biasing force between the heat exchanger device and the cooling device to effectuate and improve heat transfer. The liquid coolant may be circulated through an energy delivery device positioned in an airway of a patient to preserve tissue. The system is controlled to circulate liquid coolant at a given temperature and pressure for a selected amount of time during pulmonary treatment of a patient. |
