A transducer assembly (10) and method for coupling ultrasonic energy to a body (12) for thrombolysis of vascular thrombi is provided. The assembly includes a catalytic transducer (14) for transmitting ultrasound into a medical target transcutaneously. The catalytic transducer includes a front mass (28) having structure which optimizes the transmission of ultrasound into the body. A reservoir (32) for containing a cooling conductive medium (34) between the front mass and the body surface is provided, and is contained within the housing. The front mass (28) includes an apex (78) for accumulating expelled gasses.
L'invention se rapporte à un ensemble transducteur (10) et à un procédé permettant de coupler de l'énergie ultrasonore à un corps (12) dans le but de réaliser la thrombolyse de thrombus vasculaires. Cet ensemble comporte un transducteur catalytique (14) destiné à émettre des ultrasons dans une cible médicale par la voie transcutanée. Ce transducteur catalytique comporte une masse avant (28) dont la structure permet d'optimiser l'émission d'ultrasons dans le corps. Un réservoir (32) destiné à contenir un milieu conducteur refroidissant (34) est disposé entre la masse avant (28) et la surface du corps, et se situe à l'intérieur du boîtier. La masse avant (28) comporte une voussure (78) destinée à accumuler les gaz expulsés.
