<p>An ultrasound system is disclosed having a catheter (10) including an elongate flexible catheter body (12) having at least one lumen (18) 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 an ultrasound transducer (22). The catheter also includes a distal head (34) positioned on the distal end of the ultrasound transmission member. The catheter also has a coil (40) with a proximal end connected to the distal end of the catheter body, and a distal end connected to the distal head. The coil defines a lumen communicating with the lumen of the catheter body. The ultrasound system also includes a sonic connector for coupling the ultrasound transmission member to the transducer. Different configurations are disclosed for the distal head and the ultrasound transmission member.</p> |
