Method and apparatus for treating malignant tumors by local hyperpyrexia

An apparatus for treating a malignant tumor by local hyperpyrexia, comprising:

• a power supply having an output;
• a source of electromagnetic radiation having a first input connected to the power supply output, a second control input and an output;
• at least one electromagnetic radiation emitter connected to the radiation source output, means for positioning the at least one emitter close to any desired portion of a patient's body;
• a temperature pickup adapted to be introduced directly into the malignant tumor, the temperature pickup having an output;
• a comparison circuit having a first input, connected to the output of the temperature pickup, a second input and an output;
• a temperature setter, connected to the second input of the comparison circuit;
• a temperature control unit having an input connected to the output of the comparison circuit and an output connected to the second control input of the radiation source;
• magnetic retainer means movably arranged for retaining ferromagnetic particles within the boundaries of the malignant tumor;
• removal means for removing the contents of said tumor and comprising:
• a needle made of a magnetically soft material having a pointed end, adapted for introduction into the tumor and a blunt end, the needle having an axially extending cavity and at least one through hole close to the pointed end thereof, the diameter of the at least one through hole and the axially extending cavity being greater than the diameter of the ferromagnetic particles, the at least one through hole being in communication with the axially extending cavity;
• the needle having an outlet port for the axially extending cavity, adjacent to the blunt end of the needle;
• a source of a pulsed magnetic field magnetically coupled to the needle;
• a receiver-collector having an inlet port and another port;
• a conduit having a first end in communication with the inlet port of the receiver-collector and a second end in communication with the outlet port of the needle cavity;
• a vacuum source connected to the another part of the receiver-collector.
