Abstract
In a first embodiment, the antenna cooperatively situated with respect to an external surface of the balloon of a balloon catheter has a spiral configuration, which renders this external antenna highly directional. This first embodiment of balloon catheter is shown inserted in the urethra of a patient in a system for irradiating his prostatic tumor and measuring the tumor's temperature with a radiometer. In a second embodiment, the antenna cooperatively situated with respect to an external surface of the balloon of a balloon catheter has a helical configuration, which renders this external antenna omnidirectional.
