Endotract antenna for application of hyperthermia to malignant lesions.

Abstract

As hyperthermia treatment for deeply located malignant lesions is most difficult, two types of endotract antenna were devised, one constructed for radio frequency and the other for administration of microwave to tumors of the esophagus and colorectum. Well-controlled temperatures can be applied to the narrowed pyloric canal of dogs with these two instruments, which appear to have great promise for clinical application.
