The present invention relates to a device for mini-invasive ultrasound treatment of an object. At least one therapeutic ultrasound transducer (2) is arranged for treatment of the object (5) by generating an ultrasonic field (3), the temperature focus (F) of which is located in the object (5) for heating thereof. The therapeutic ultrasound transducer (2) comprises a probe (10) adapted to be inserted into the body in the direction towards the object (5) and comprises a front portion (l0a) adapted to be located at, against or in the object (5). Said probe (10) comprises at least one transmitter element (11) for generating said ultrasonic field (3). The transmitter element (11) for generating the ultrasonic field (3) is arranged behind the front portion (l0a) such that the transmitter element (11) does not heat or substantially not heat the front portion (l0a) when in operation.
L'invention concerne un dispositif de traitement mini-invasif par ultrasons d'un objet. Un transducteur (2) de thérapie par ultrasons permet de traiter ledit objet (5) par production d'un champ ultrasonore (3) dont le foyer thermique (F) est situé dans l'objet (5) pour le réchauffement de ce dernier. Ledit transducteur (2) de thérapie par ultrasons comprend une sonde (10) conçue pour être insérée dans la peau du corps en direction de l'objet et une partie avant (l0a) conçue pour être disposée au niveau ou contre ledit objet (5). Ladite sonde (10) comprend au moins un élément d'émetteur (11) permettant de générer le champ ultrasonore (3). L'élément d'émetteur (11) permettant de générer le champ ultrasonore (3) est agencé derrière la partie avant (l0a) de sorte que ledit élément ne chauffe pas (11) ou sensiblement peu ladite partie avant (l0a) pendant son fonctionnement.
