  • Microwave applicator for transurethral hyperthermia
    Patent number: 5301687
    Abstract: A radiant heating apparatus for deployment within an animal body to radiate heat-producing electromagnetic energy into the body includes an antenna mounted on a catheter element and connected to an electrical transmission line having first and second conductors for feeding electrical current from a source to the antenna. The apparatus has the improvement in which the antenna comprises a first radiating element carried on the catheter element and extending from an antenna feed junction in a first direction along a first elongation axis. The first radiating element is connected to the first transmission line conductor at the feed junction and presents a first selected impedance to the feed junction. A second radiating element is carried on the catheter element and extends from the feed junction in a second direction opposite to the first direction along the first axis.
