Abstract

The invention pertains to an angioplasty catheter for expanding and/or opening up morbidly constricted or obstructed blood vessels, comprising at least one rotor (3) that is rotatively mounted in a cylindrical housing (4) at the distal end of the catheter, is connected to a rotational actuator (2) and is guided in the axial and/or radial direction along a preset path of motion (5), where as a result of the guided motion, the turning rotor (3) mechanically generates endogenous sound waves, especially sound waves in the ultrasound range, and induces a corresponding motion of the housing (4).
