Abstract
An ultrasound transmission device for utilizing ultrasound energy ultrasound to treat intravascular conditions, such as stenotic and occluded regions of blood vessels, is provided. The ultrasonic transmission device includes a transmission member connectable to the ultrasound energy source on a one end and a tip on the other end. The tip includes a distal section, a proximal section and an intermediate section. The proximal section has a first diameter larger than the transmission member diameter. The intermediate section includes a decreasing step portion, a narrowed portion, and an increasing step portion.
