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 positioned at the distal end of the catheter body and secured to the distal end of the ultrasound transmission member; and
a guidewire tube extending at least partially through the lumen of the catheter body and attached to the ultrasound transmission member.

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.
