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.

Ultrasound transmission apparatus having a tip

An ultrasonic treatment system and method for utilizing ultrasound to treat intravascular conditions, such as stenotic and occluded regions of blood vessels, are provided. The ultrasonic treatment system includes an ultrasonic probe, having a proximal and distal end. A guide catheter and guidewire may also be provided and the probe can be slidably disposed within the guide catheter's inner lumen. The probe can include a horn at the proximal end, a transmission member with a proximal and a distal end connected to the horn at the transmission member proximal end, and a distal tip connected at the transmission member's distal end. The transmission member may include one or more transmission wires, having proximal and distal ends, connected serially or in parallel.
