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.
Claims4
A combination microwave heater and cooling device for use in heat treatment of cancerous tumors, the cooling device being disposed between said microwave heater and adjacent said cancerous region to be treated, the cooling device including at least one tube through which a refrigerant is circulated, the tube comprising a porous, expanded polytetrafluoroethylene resin having interconnecting pores.
