Zusammenfassung:Catheters configured to substantially simultaneously cut or score a lesion and deliver a pressure wave to the lesion. An illustrative catheter may comprise a catheter shaft, an expandable member secured to a distal portion of the catheter shaft, a cutting member secured to the expandable member, and an ultrasound transducer disposed within the expandable member. Tethers may be attached between the expandable member and the emitter that self-orientate the emitter towards target tissue due to uneven expansion of expandable member due to different compliance between target tissue and surrounding tissue.
