<P>PROBLEM TO BE SOLVED: To provide a therapeutic ultrasound system with a protective feature that minimizes the introduction of debris into the patient's vasculature to remove obstruction in a tubular body structure like a blood vessel even if an ultrasound transmission member were to break, fracture or come off during a medical procedure. <P>SOLUTION: An ultrasound catheter has an elongate catheter body having a lumen extending longitudinally therethrough, and an ultrasound transmission member extending longitudinally through the lumen of the catheter body. The ultrasound transmission member has a proximal end that is coupled to a separate ultrasound generating device, and a distal end that terminates at the distal end of the catheter body, with at least part of the distal end of the ultrasound transmission member extending outside the lumen of the catheter body and beyond the distal end of the catheter body, and with the ultrasound transmission member directly attached to the catheter body via a connecting device. <P>COPYRIGHT: (C)2013,JPO&INPIT |
