1. An ultrasonic recanalization system comprising an ultrasonic transducer in a handle and energized by a switch, said transducer connected at its proximal end to a console containing control means of the ultrasonic energy level applied, determined by a measuring device of the frequency and amplitude provided at the distal end of the transducer, a triple lumen catheter that can be entered into a patient, and a hollowed tube which can be entered into the patient'"'"'s artery through said catheter, said hollowed tube operatively connected to said transducer for receiving ultrasonic energy and transferring such energy into the patient'"'"'s artery, said tube having an ending with a bent portion having a flexible tip, and said catheter having a flow blocking device on its outer circumference which includes means for inflating when required to secure said tip in position and obstruct the flow of blood near a stenosis blockage site in the artery, and said catheter having a concentric canal passage for surrounding said hollowed tube through which a liquid solution can be pumped in from a reservoir by a pump provided in said console, said hollowed tube including aspiration means whereby said solution can then flow out after washing off the stenosis splinters and blood into a second reservoir provided in said console, through said hollowed tube.
