MICROWAVE ANTENNA SYSTEM FOR INTRACAVITARY INSERTION

摘要

A microwave antenna system for intracavitary insertion for inducing hyperthermia by microwave irradiation is provided for cancer treatment and the like. An elongated antenna (11) is adapted to laterally propagate a generally uniform field of microwaves of a wavelength of85 to 120cm. A dielectric jacket (22) surrounds the antenna having a closed outer end (24), but open at its inner end (26). The jacket is equipped with air circulation conduits (30, 32) to cool the tissue in the immediate vicinity of the jacket.
