Abstract
An ultrasound catheter has an elongate flexible 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 tip that is attached to the distal end of the ultrasound transmission member and which is located at the distal end of the catheter body. The ultrasound transmission member is directly attached to the catheter body and/or to a guidewire tube either directly or via an attachment device. The catheter has an additional radiopaque marker positioned on the distal end the catheter.
Claims22
An ultrasound catheter comprising:
- a catheter body having a lumen;
- an ultrasound transmission member disposed in the lumen;
- a tip component distally disposed on the catheter body and distally secured to the ultrasound transmission member;
- a section proximally disposed on the catheter that facilitates connecting the ultrasound transmission member to an ultrasound generating device;
- a hollow guidewire tube disposed in the lumen and attached to the ultrasound transmission member proximal of and separated from the tip component and independent of the catheter body;
- and
- a guidewire passing through the hollow guidewire tube.
