Abstract[English]
A catheter assembly comprising: a high intensity therapeutic ultrasound (HITU) transducer shaped as a cylindrical shell that includes an inner surface defining a chamber, an outer shell for launching ultrasound waves outward, a proximal rim and a distal rim between the inner surface and the outer shell; a post structure located in the chamber and electrically connected to the inner surface of the cylindrical shell; and a flex circuit comprising at least one signal pad electrically connected the outer shell of the HITU transducer and at least one ground pad electrically connected to the post structure.[French]
L'invention concerne un ensemble cathéter comprenant : un transducteur ultrasonore thérapeutique à haute intensité (HITU) en forme d'enveloppe cylindrique qui comporte une surface interne définissant une chambre, une enveloppe externe permettant de lancer des ondes ultrasonores vers l'extérieur, un rebord proximal et un rebord distal entre la surface interne et l'enveloppe externe ; une structure à plots située dans la chambre et connectée électriquement à la surface interne de l'enveloppe cylindrique ; et un circuit souple comprenant au moins un plot de signal connecté électriquement à l'enveloppe externe du transducteur HITU et au moins un plot de masse connecté électriquement à la structure à plots.
