Abstract: In a thermal therapy apparatus for treating a vital tissue by irradiating the tissue with a laser beam, a display unit displays a figure indicating the shape of a diseased part to be heated on the basis of information concerning the diseased part. Heating regions are arranged in the displayed figure indicating the diseased part shape by using identifiers corresponding to individual heating conditions. In accordance with size/position information of these heating regions arranged, heating conditions such as the laser intensity laser irradiation time and laser irradiation angle are set. Laser beam irradiation is performed by controlling the irradiation in accordance with the set heating conditions. The information pertaining to the diseased part can also be input on the basis of an ultrasonic signal from an ultrasonic probe separated from or installed in the laser irradiation portion.

Abstract: An side irradiating type laser ray irradiation apparatus for irradiating a tissue with a laser ray having a deep transmitting capability for the purpose of treating, for example, Benign Prostatic Hyperplasia, cancer or other tumors. The apparatus includes an irradiating unit for reflecting the laser ray, a transporting device for transporting the irradiating unit, and an interlocking device for changing the irradiation angle of the laser ray in correspondence with the movement so that the laser ray radiated from the moving irradiating unit always passes through the same point. Since the laser ray constantly passes through a point in a deep area of the tissue, it is capable of effectively heating only the deep lesional region.

The irradiated laser rays crosses the target area, which is the center and its vicinity of a circle that includes the curved track. The areas surrounding the target area are maintained at relatively low temperatures as the laser ray irradiating position is constantly changing. On the other hand, the temperature of the target area rises to a specified temperature because the laser rays concentrate there.
