Ultrasound catheter having protective feature against breakage
First Claim
1. An ultrasound catheter, comprising:
- an elongate flexible catheter body having a proximal end, a distal end and a lumen extending longitudinally therethrough;
an ultrasound transmission member extending longitudinally through the lumen of the catheter body, the ultrasound transmission member having a proximal end that is coupled to a separate ultrasound generating device;
a tip having a proximal end and a distal end, the tip being positioned at the distal end of the catheter body and secured to a distal end of the ultrasound transmission member; and
a guidewire tube extending at least partially through the lumen of the catheter body, the guidewire tube being directly connected to the ultrasound transmission member via an attachment member and an adhesive at least at a location that is spaced from the tip, the guidewire tube having a lumen configured to receive a guidewire,wherein the ultrasound transmission member is disposed entirely outside the lumen of the guidewire tube.

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.
