Patent number: 5231997Abstract: A heating apparatus for hyperthermia utilizes electromagnetic waves for locally heating cancerous cells within a living body. Electromagnetic waves output from a single electromagnetic wave generating means are branched into a plurality of branched electromagnetic waves, which are respectively employed to conduct hyperthermia treatments for a plurality of patients. The whole of the hyperthermia system is controlled in a concentrated fashion from a single section by means of time-division multiplexing. It is therefore possible for a plurality of patients to be subjected to hyperthermia treatment at the same time and in parallel with each other, even when the conditions of these patients differ from one another. Further, it is advantageously possible to simplify the arrangement of the system as a whole and stabilize the control of the system.Type: GrantFiled: February 28, 1991Date of Patent: August 3, 1993Assignees: Tokyo Keiki Co., Ltd., Makoto Kikuchi, Shinsaku Mori, Yoshio NikawaInventors: Makoto Kikuchi, Shinsaku Mori, Yoshio Nikawa, Takashige Terakawa

Patent number: 4891483Abstract: The applicator used in this invention functions as an antenna for delivering electromagnetic energy into a living body. The applicator is supported by a supporting mechanism through a supporting device. The applicator can move to and stop at a position through the action of this supporting mechanism. A cooling section is provided on the contact surfaces of the applicator and the living body so as to protect normal cells on the surface of living body. This cooling section is additionally provided with a coolant circulating device, which enables to continuously perform hyperthermia for a long period of time.

Patent number: 4841990Abstract: The applicator of this invention functions as an antenna of electromagnetic waves when used in hyperthermia. The casing of this applicator serves as waveguide.The applicator incorporates in its casing an electromagnetic lens. It is also provided with a cooling mechanism for cooling the body surface of the heated region at an opening of the casing. When electromagnetic waves which have been introduced from outside to the supply portion propagate in the human body from the opening of the casing, energy reflection is generated due to untuned impedance. In order to prevent this reflection, the applicator of this invention incorporates three stub tuners which can be adjusted from outside so as to reduce the loss of energy.The casing of the applicator of this invention is filled with fluid such as machine oil which has a small damping factor so as to reduce the loss of electromagnetic waves in the casing which occurs during its propagation. The three stub tuners are waterproofed at their movable portion.Type: GrantFiled: June 25, 1986Date of Patent: June 27, 1989Assignee: Tokyo Keiki Co., Ltd.Inventors: Makoto Kikuchi, Shinsaku Mori, Yoshio Nikawa, Takashige Terakawa

Patent number: 4841989Abstract: A very large proportion of electromagnetic waves are reflected by the surface of the human body. To cope with this phenonmenon, the applicator of the present invention incorporates an electromagnetic lens at an electromagnetic wave-radiating end portion thereof, thereby enabling electromagnetic waves propagated in the human body to be gradually focused into a portion of the body to be heated. An omnidirectional electromagnetic lens is employed.Affected parts located at different depths in the body are generally treated by different applicators. However, the applicator of the present invention is constructed so that the electromagnetic lens is replacable. In consequence, only one case for the applicator is required. This makes the use of the applicator easier.For the purpose of providing a small-sized electromagnetic lens and applicator, coolant is made to flow inside the electromagnetic lens.Type: GrantFiled: June 25, 1986Date of Patent: June 27, 1989Assignee: Tokyo Keiki Co., Ltd.Inventors: Makoto Kikuchi, Shinsaku Mori, Yoshio Nikawa, Takashige Terakawa
