An ultrasound system has a catheter (10) including an elongate flexible catheter body (12) having at least one lumen extending longitudinally therethrough. The catheter further includes an ultrasound transmission member (30) extending longitudinally through the lumen of the catheter body, the ultrasound transmission member having a proximal end connectable to a separate ultrasound generating device (24) and a distal end coupled to the distal end (16) of the catheter body. The distal end of the catheter body is deflectable. The ultrasound system also includes a sonic connector (66) that connects the ultrasound transmission member to an ultrasound transducer (22). The ultrasound system also provides a method for reverse irrigation and removal of particles.
