Abstract
Ultrasonic apparatus for clot dissolution includes a radiator for coupling ultrasonic waves 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. A seed liquid is introduced proximate the radiator for promoting cavitation of intravascular fluid. In addition, enhancement of clot dissolution by chemical agents is shown to be significantly increased when combined with ultrasonic energy.
