Patent 5080102 Issued on January 14, 1992. Estimated Expiration Date: April 21, 2009. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.
A hyperthermia treatment apparatus combining a generator of a focused ultrasonic beam comprising a main high frequency electric wave emitter and a main piezoelectric transducer whose active surface is focusing, with an echography device comprising an auxiliary high frequency electric pulse generator associated with an auxiliary piezoelectric transducer and means for causing the zone to be treated to be swept by the ultrasonic examination beam generated by said auxiliary transducer; and with switching and adjustment means for causing, during a main treatment and checking operating mode, emission of said focused beam by said main transducer energized by said main emitter during periodic time intervals separated by shorter time intervals during which the emission of the examination beam and the formation of echographic images are effected.
