An ultrasound catheter adapted for accessing small vessels in the distal anatomy is disclosed. The ultrasound catheter 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 member (124) 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.

L'invention concerne un cathéter ultrasonore conçu pour accéder à de petits vaisseaux situés dans des régions distales de l'anatomie. Le cathéter ultrasonore comprend un corps tubulaire allongé qui comporte une lumière d'apport. La flexibilité et les dimensions du corps tubulaire lui permettent d'accéder aux régions distales de l'anatomie par glissement sur un fil guide. Un élément ultrasonore rayonnant, prévu sur la partie d'extrémité distale du corps tubulaire, émet de l'énergie ultrasonore au site de traitement. Une solution médicamenteuse peut aussi être administrée au site de traitement par la lumière d'apport et un orifice de sortie.
