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.

La flexibilité et les dimensions dudit corps tubulaire permet d'accéder à l'anatomie distale, ce dernier avançant sur le fil guide. Un élément (124) de rayonnement à ultrasons est disposé le long de l'extrémité distale (106) dudit corps tubulaire pour émettre de l'énergie ultrasonore sur un site de traitement. Une solution de médicament peut également être libérée à travers la lumière d'administration (112) et à l'extérieur d'un orifice de sortie (114) vers le site de traitement.
