An ultrasonic tissue ablation device comprising a transversely vibrating small- diameter probe (10) and a coupling assembly for probe attachment and detachment that that enables the probe (10) to disengage from the device body. The probe detachability allows for insertion, manipulation, and withdrawal independently of the device body. The probe (10) can be used with acoustic and/or aspirations sheaths to enhance tissue ablation. The device body includes an ultrasonic energy source and a horn assembly (34). The probe (10) of the present invention is engaged to the device body in a manner which creates an impedance mismatch between the probe (10) and the device body which allows the probe and the device body to operate as separate acoustic systems. The present invention also comprises a method for the removal of vascular occlusions in a blood vessels.

L'invention concerne un dispositif à énergie ultrasonore destiné à l'ablation de tissus, comprenant une sonde de petit diamètre (10) à vibration transversale et un ensemble de raccordement conçu pour monter et démonter la sonde, permettant de retirer la sonde (10) du corps du dispositif. Cet ensemble de raccordement permet d'insérer, de manipuler et de retirer la sonde par rapport au corps du dispositif. La sonde (10) peut être utilisée avec une gaine acoustique et/ou d'aspiration pour que l'ablation du tissu soit plus efficace. Le corps du dispositif comprend une source d'énergie ultrasonore et un ensemble de pointe (34). La sonde (10) de la présente invention est fixée sur le corps du dispositif de façon à créer une désadaptation d'impédance entre la sonde (10) et le corps du dispositif, permettant de faire fonctionner la sonde et le corps du dispositif comme deux systèmes acoustiques séparés. La présente invention concerne également une méthode destinée à l'ablation d'occlusions vasculaires dans des vaisseaux sanguins.
