Abstract (en)

[origin: WO9900061A1] 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.
