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.

Abstract: A tubular medical device comprises a tubular body, a lumen, a compression-resisting member inserted in the lumen so that it cannot move in the direction of the axis of the tubular body, with its distal end located at a predetermined distance from the distal end of the tubular body toward the proximal end, a pull wire whose distal end is secured near the distal end of the tubular body at a position deviated from the axis of the tubular body and which is led in the tubular body to the proximal end of the tubular body, and a pulling mechanism for pulling the pull wire toward the proximal end of the tubular body which is attached to the proximal end of the tubular body and has an manipulating dial. The compression-resisting member consists of a main body and a secured portion. The compression-resisting member main body, and has a property of resisting compression in the axial direction of he tubular body. The secured portion retains the rain part in place in the lumen.

Abstract: A thermal treatment apparatus comprises a control unit 251a that stops issuing a signal for laser beam activation transmitted over the foot switch signal cable 291 when the temperature obtained by the mirror temperature sensor 111 that detects the temperature of the laser emission part 122 provided at the laser irradiation unit 1 exceeds a predetermined value. This stops the output of the laser beam from the laser generator 3. Alternatively, the control unit can adjust the output value of the laser beam generated by the laser beam generator 3 by transmitting a signal via the communication cable 293 to change it in accordance with the detection signal of the mirror temperature sensor 111.

Abstract: The invention relates to a thermal treatment apparatus capable of irradiating targeted lesions with energy to obtain good treatment results.

Abstract: An energy irradiation apparatus for medical treatment of tissues through irradiation of energy including a long main unit, an emitting part, a power transmission member, a drive mechanism, a first engaging member, and a second engaging is disclosed. The emitting part is disposed moveably inside a distal end of the main unit for emitting energy transmitted to a distal side from a proximal side. The power transmission member is disposed moveable inside the main unit. The emitting part is mounted to a distal end of the power transmission member. The drive mechanism reciprocates the power transmission member in a longitudinal direction of the main unit. The first engaging member is provided inside the power transmission member for receiving a drive force from the drive mechanism. The second engaging member is provided in the drive mechanism for engaging removably with the first engaging member.
