Therapeutic ultrasound system
First Claim
1. An ultrasound catheter comprising:
- an elongated catheter body having a proximal end, a distal end and at least one lumen extending longitudinally therethrough;
a proximal housing that is coupled to the proximal end of the elongated catheter body, the proximal housing having a distal bore;
an ultrasound transmission member extending longitudinally through the lumen of the catheter body;
a sonic connector positioned on the proximal end of the ultrasound transmission member for connecting the ultrasound transmission member to a separate ultrasound generating device at a connection location, the sonic connector comprising a proximal section for connection to the separate ultrasound generating device, and a front portion which connects to the proximal end of the ultrasound transmission member;
andan absorber retained inside the distal bore of the proximal housing and which substantially surrounds the ultrasound transmission member.

Abstract
An ultrasound system has a catheter including an elongate flexible catheter body having at least one lumen extending longitudinally therethrough. The catheter further includes an ultrasound transmission member extending longitudinally through the lumen of the catheter body, the ultrasound transmission member having a proximal end connectable to a separate ultrasound generating device and a distal end coupled to the distal end of the catheter body. The distal end of the catheter body is deflectable. The ultrasound system also includes a sonic connector that connects the ultrasound transmission member to an ultrasound transducer. The ultrasound system also provides a method for reverse irrigation and removal of particles.
