The present invention concerns a device for treatment by hyperthermia, comprising unipolar probes of the implantable type, and comprising circuitry for modifying the distribution forms of the electrical field applied to an aera to be treated.

Device for treatment through hyperthermia

The present invention concerns a device for treatment by hyperthermia, comprising unipolar probes adapted to be disposed in an area to be treated of a patient, and comprising vector tubes intended to be implanted in the said area to be treated and to contain, at each hyperthermia session the said unipolar probes.

A hyperthermia apparatus primarily applicable to the treatment of tumors comprises at least three high-frequency generators connected to three electrodes. The electrodes are intended to be coupled to a patient's body which constitutes the load, thus producing a higher temperature rise in the vicinity of a fictitious electrode in the body. The generators have adjustable phases and amplitudes, the output of each generator being connected to each of the three electrodes.

Hyperthermia apparatus

An apparatus for thermal treatment of the human body, using electromagnetic waves (200 to 2500 Mc/s) and radiometric receivers for monitoring and possibly controlling the temperature reached by the living tissues. A generator at ultra high frequency delivers a power of about one Watt into a coaxial cable terminated by a probe emitting electromagnetic waves in the organ to be heated by dielectric losses in the medium. A multichannel receiver, switched at intervals, analyzes the radiation reemitted by the living tissues through the probe, then utilized as a receiving antenna. The temperature reached in a region surrounding the probe is deduced therefrom and can be utilized for controlling the power emitted through a servocontrol system.
