The ultrasonic catheter, being the catheter itself of long flexibiility, passing by the lumen of the catheter itself and the catheter itself which, possess the lumen which passes by the catheter itself to longitudinal direction to longitudinal direction extending has with the ultrasonic transmission component which is present. The ultrasonic transmission component has end in the proximal edge and the distal (2036) edge of the catheter itself which are connected to the ultrasonic generator which is separated, at least as for portion of the distal (2036) edge of the ultrasonic transmission component exceeding the distal (2036) edge of the catheter itself outside lumen of the catheter itself, the extending being present, the ultrasonic transmission component through connecting means, is directly connected to the catheter itself.< Selective figure >Figure 1超音波カテーテルは、細長い可撓性のカテーテル本体であって、カテーテル本体を長手方向に通る内腔とを有するカテーテル本体と、カテーテル本体の内腔を長手方向に通って延在する超音波伝達部材とを有する。超音波伝達部材は、分離した超音波発生器に接続される近位端とカテーテル本体の遠位端に末端を有し、超音波伝達部材の遠位端の少なくとも一部はカテーテル本体の内腔の外側にカテーテル本体の遠位端を越えて延在し、超音波伝達部材は接続手段を介してカテーテル本体に直接接続される。【選択図】図1
