Abstract
A cooling device is provided for use in cooling surrounding human tissue during hyperthermia treatment of a cancerous tumor. The device comprises at least one tube constructed of a fluororesin having continuous pores, such as porous, expanded polytetrafluoroethylene, placed in a desired configuration adjacent the tissue to be cooled, and through which flows a coolant. Microwaves used in hyperthermia treatment of cancerous tumors can pass through the device and heat the tumor to be treated to a higher degree than heretofore possible because the adjacent noncancerous tissue can now be cooled. Because the tube is porous, the cooling effect is pronounced.
