摘要： An ultrasonic system for the recanalization of body vessels includes an ultrasonic transducer (3) adapted for in-situ insertion into body vessels, an ultrasonic power generator (1) as well as a highly insulated electrical cable (2) for conveying electrical power generated by said generator (1) towards said transducer (3) located in-situ into a body vessel. The ultrasonic transducer (3) is adapted for coupling to a catheter for guiding at the site of the occlusion in the vessel. Echoes from the occlusion are monitored, thereby permitting localisation of the transducer (3) in the body vessel.
