Small vessel ultrasound cathter

a small blood vessel and ultrasound cathter technology, applied in the field of catheters, can solve the problems of inability to manufacture a sufficiently small diameter ultrasound catheter for use in small blood vessels, lack of flexibility necessary for navigation through difficult distal anatomy regions, and inability to adapt well to effective use of ultrasound catheters in small blood vessels in the distal anatomy. , to achieve the effect of reducing trauma or damage to tissue, facilitating catheter advancement, and reducing bending resistan

Abstract

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