An ultrasonic ablation device for effecting ultrasonic ablation of intravascular obstructions such as plaque or thrombi. The ultrasonic ablation device has a) an elongate catheter body (12), b) a wave guide or ultrasound transmission wire (20) extending through the elongate catheter body (12), and c) a distal head or probe member (22) positioned at the distal end of the catheter body. A guidewire lumen or passageway (14) extends longitudinally through the catheter body (12) and a guidewire aperture or passageway (60) extends through the distal head or probe (22) such that a guidewire (34) may be passed through the distal head or probe (22) and through the catheter body (12). Also disclosed is an improved distal head or probe which may be incorporated in any elongate ultrasonic ablation device, the improvement comprising the formation of a concavity or indentation in the distal or frontal face (23) of the distal head or probe (22) to improve the cavitation created thereby.

L'invention concerne un dispositif ultrasonique d'ablation permettant d'effectuer une ablation ultrasonique d'obstructions intravasculaires telles que de la plaque ou des caillots sanguins. Le dispositif d'ablation ultrasonique possède a) un corps de cathéter allongé (12), b) un guide d'onde ou un fil de transmission ultrasonique (20) s'étendant à travers le corps du cathéter allongé (12), et c) une tête distale ou élément sonde (22) positionné à l'extrémité distale du corps du cathéter. Un orifice ou passage (14) du fil de guidage s'étend longitudinalement à travers le corps du cathéter (12) et un orifice ou un passage (60) du fil de guidage s'étend à travers la tête ou sonde distale (22) de sorte qu'un fil de guidage (34) puisse être passé à travers la tête ou sonde distale (22) et à travers le corps du cathéter (12). L'invention décrit également une tête ou sonde distale améliorée qui peut être incorporée dans n'importe quel dispositif d'ablation ultrasonique allongé, l'amélioration consistant à former une concavité ou une découpure dans la face frontale ou distale (23) de la tête ou sonde distale (22) afin d'améliorer la cavitation ainsi créée.
