A microwave hyperthermia apparatus that can be inserted into the body which includes a hollow central tube for the insertion of radioactive therapy sources. The use of a coaxial transmission line impedance transformation along the insertable portion of the coaxial cable enables a reduction in the characteristic impedance by increasing the outer diameter of the inner coaxial conductor so that the center conductor can be a metal tube. If the ratio of the outer coaxial conductor diameter vs. the inner coaxial conductor is decreased, the characteristic impedance of the transmission line is lowered. This enables the inner conductor diameter to increase sufficiently to make the central hollow opening large enough to receive standard radioactive sources therein. This provides for a good impedance match that improves microwave energy efficiency while at the same time permitting a large hollow center opening. The combination of the microwave antenna device and brachytherapy sources provides for enhanced effectiveness when the two treatments are delivered simultaneously or in close time proximity to each other.

A microwave hyperthermia treatment system employs a set of antennas individually controllable to provide different phase and amplitude outputs and controlled to cycle through different sets of phases and amplitudes over time to minimize the effect of hotspots formed by any given set of phases and amplitudes and creating limiting high temperatures outside of a desired treatment area.

Microwave hyperthermia treatment device includes a microwave generation unit, a power supply unit, and a control unit including an exposure-time actuation timer, an intermittent actuation timer, a second-device connecting terminal, and a remote switch. Two microwave hyperthermia treatment devices are connected with each other via the second terminal connecting terminals for simultaneous use flanking the torso along either side of an affected area, whereby superposed strong microwaves are irradiated. The temperature of tumor(s) in the affected area can thereby be brought to about 43° C. in about 1 minute, rendering lengthy treatment periods unnecessary and thus alleviating temperature stress on the patient. Two remote-control switches to the control unit can be provided, one of which may be given to a patient for use as an emergency stop switch, eliminating the necessity of having to insert a temperature sensor in the body, which also alleviates the burden on the patient.
