ABSTRACT:
This invention related to a catheter comprising a tube-like basic body with a proximal and a distal end and a high-frequency generator associated with the catheter used for the purpose of generating high-frequency mechanical vibrations at the distal end of the catheter. The catheter comprises a lumen to be filled with liquid which is connected at the proximal end to an area inside of which a high-frequency movable member of the high-frequency generator is located and wherein at the distal end of the catheter a guide have been arranged for deflecting high frequency longitudinal waves traveling through the liquid inside the lumen in a lateral direction.
