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).
L'invention concerne un cathéter pour angioplastie, utilisé pour élargir et/ou ouvrir des vaisseaux sanguins resserrés ou obstrués par la maladie, comprenant, à son extrémité distale, un rotor (3) monté rotatif dans un boîtier cylindrique (4), relié à un dispositif d'entraînement en rotation (2) et soumis à un guidage forcé (5) dans le sens axial et/ou radial. Grâce à son guidage forcé, le rotor (3) en rotation génère mécaniquement des ondes sonores endogènes, en particulier des ondes sonores comprises dans la plage des ultra-sons, et induit un déplacement correspondant du boîtier (4).
