First Claim
Patent Images
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, and a distal end that terminates at the distal end of the catheter body;
a tip having a distal end and a proximal end being secured to the ultrasound transmission member, the tip being positioned at the distal end of the catheter body, and at least a portion of the tip extending beyond the distal end of the catheter body and having a width greater than a width of the catheter body; and
an intermediate member positioned between and attached to the ultrasound transmission member and the catheter body to form a continuous cross-section between at least a portion of the ultrasound transmission member and at least a portion of the catheter body so as to inhibit longitudinal movement of the ultrasound transmission member relative to the catheter body, wherein the entire intermediate member is disposed on a proximal side of the proximal end of the tip.

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.
