SMALL VESSEL ULTRASOUND CATHETER

摘要

An ultrasound catheter adapted for accessing small vessels in the distal anatomy is disclosed. The ultrasound catheter (100) comprises an elongate tubular body (102) formed with a delivery lumen (112). The flexibility and dimensions of the tubular body allow access to the distal anatomy by advancement over the guidewire. An ultrasound radiating element (124) is provided along the distal end portion (106) of the tubular body for emitting ultrasound energy at a treatment site. A drug solution may also be delivered through the delivery lumen (112) and out an exit port (114) to the treatment site.
