PROBLEM TO BE SOLVED: To reduce influence on the skin other than treatment part or on the living tissue in propagation, in a micro-machine embedded in the body, by converting an external ultrasonic wave into an electric power and making diagnosis or treatment using this power. SOLUTION: A micro-machine part 30 with a therapeutic type piezoelectric transducer 35 facing the stricture side is inserted into the vein using a catheter or the like, and arranged immediately before the stricture; and then, a treatment starting instruction is inputted from a transmitting means, with an ultrasonic wave for a power source transmitted from an ultrasonic transducer 11. As a result, the ultrasonic transducer 31 of the micro-machine part 30 receives an ultrasonic wave, which is converted to a pulse signal by the transducer 31; and further, the pulse signal is demodulated, converted to an electric power, and charged to the power source. With the power source charged with electricity, a controller opens the outlet 37a of a medicine dosing part, transmitting a therapeutic ultrasonic wave from the piezoelectric transducer 35. |
