1. An ultrasonic device for treatment of an anatomical anomaly, said device comprising:

  • (a) a power transducer in the form of a self-focussing cup associated with a power excitation generator generating power wave trains and with an echographic device transmitting an echographic beam and using said transducer as an echo receiver, said device further comprising;

    (b) means for causing said echographic device continuously to oscillate during the treatment, at an oscillation speed and with an amplitude adapted for obtaining real time echographic beam scanning of a region of space containing the anatomical anomaly, and(c) means for exciting said power transducer to produce treatment waves at moments when the echographic beam scans a predetermined restricted portion of said region.
