ULTRASOUND TRANSMISSION MEMBER HAVING IMPROVED LONGITUDINAL TRANSMISSION PROPERTIES

摘要

An elongate ultrasound transmission member (22) having regions (26, 28, 30, 32) of differing cross-sectional dimension or diameter. A sleeve, sheath or other damping member (40) may be positioned around a portion (30) of the ultrasound transmission member (22) to dampen or limit transverse side-to-side movement of such portion (30) of the member (22). The ultrasound transmission member (22) may be incorporated into a flexible catheter body (20) to form an ultrasound delivering medical catheter (10).
