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; and
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, and a distal end that terminates at the distal end of the catheter body, with at least a portion 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 an attachment device.

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 end that terminates at the distal end of the catheter body, with at least a portion 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 an attachment device.
