Abstract: A system comprises an elongate instrument including a first and second channels. The system also comprises an expandable device coupled to the elongate instrument. The expandable device is in fluid communication with the first and second channels. The system also comprises a pump for circulating a fluid through the first and second channels and a heating system for heating the fluid. The system also comprises a drainage system for removing the fluid from the expandable device and restricting drainage flow. A control system controls temperature and delivery of the heated fluid through the first channel and the second channel to heat the elongate instrument and the expandable device with the heated fluid while maintaining the expandable device in an uninflated configuration, inflate the expandable device with the heated fluid, ablate an anatomic passage with the inflated and heated expandable device, and deflate the expandable device.
