Abstract
Abstract A microwave radiator formed 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 192 , and electrically connecting a central electrical conductor to a coaxial electrically-conducting jacket.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
55 words
A probe to invade a living organism, said probe comprising antenna means defining an antenna; a radioactive substance within said antenna means, and means for connecting said antenna means to a source of energy so that said probe can simultaneously deliver to said organism thermo-radiation from said antenna means and ionizing radiation from said substance.
Claim 2
Dependent Claim
55 words
A probe to invade a living organism, said probe comprising antenna means defining an antenna; a radioactive substance within said antenna means, and means for connecting said antenna means to a source of energy so that said probe can simultaneously deliver to said organism thermo-radiation from said antenna means and ionizing radiation from said substance.
Claim 3
Dependent Claim
68 words
The probe recited in claim 1, wherein said means for connecting said antenna means to a source of energy includes a coaxial conduit having a central electrical conductor and a coaxial electrically-conducting jacket; the antenna means is a helical electrical conductor formed at least partially of said radioactive substance and electrically connecting said central electrical conductor of said coaxial conduit and said coaxial electrically-conducting jacket of the conduit.
Claim 4
Dependent Claim
13 words

Claim 7
Dependent Claim
81 words
A probe to invade a living organism and to simultaneously deliver to tissue in the organism both microwave energy from a microwave energy source and nuclear radiation, the probe comprising: (a) a coaxial conduit having a central electrical conductor, a coaxial electrically-conducting jacket, and a first end adapted to be electromagnetically connected to the source, and a second end, and (b) a microwave antenna attached to the second end of the conduit and formed at least partially of a radioactive substance.
Claim 8
Dependent Claim
81 words
A probe to invade a living organism and to simultaneously deliver to tissue in the organism both microwave energy from a microwave energy source and nuclear radiation, the probe comprising: (a) a coaxial conduit having a central electrical conductor, a coaxial electrically-conducting jacket, and a first end adapted to be electromagnetically connected to the source, and a second end, and (b) a microwave antenna attached to the second end of the conduit and formed at least partially of a radioactive substance.
