ABSTRACT:
Ultrasonic apparatus for clot dissolution and plaque ablation includes a radiator for coupling ultrasonic waves into plaque and a piezoelectric crystal, connected with said radiator, for the intravascular generation of ultrasonic waves; said ultrasonic waves being propagated along a longitudinal axis of said piezoelectric crystal and having an inertial node position within said piezoelectric crystal. The piezoelectric crystal is constructed in order to prevent significant power loss caused by a shifting of the inertial node of the generated ultrasonic waves to a position exterior to said piezoelectric crystal due to loading of the radiator-means caused by the coupling of ultrasonic waves into the clot or plaque.
