Abstract
A microwave radiator formed at least partially of a radioactive substance and adapted to simultaneously deliver microwave energy and nuclear radiation to living tissue. The radiator is incorporated into an interstitial or intracavitary probe. The radiator is a helical electrical conductor, formed of a radioactive substance such as iridium.sup.192, and electrically connecting a central electrical conductor to a coaxial electrically-conducting jacket. Alternatively, a microwave antenna is formed as part of a probe with a cavity adapted to receive sources of ionizing radiation. Preferably, the cavity is part of a channel through a conduit carrying the probe, the channel being connected to a device for delivering ionizing radiation sources to the probe after positioning at the target tissue and after a heating regime. The device is able to remove the ionizing sources while leaving the microwave source in place for an additional heating regime. Other therapeutic regimes are facilitated by the combination.
