Title
(EN) ULTRASOUND-GUIDED ABLATION CATHETER AND METHODS OF USE
(FR) CATHETER D'ABLATION A GUIDAGE ULTRASONIQUE ET MODALITES DE MISE EN OEUVRE
Abstract
(EN)
The present invention provides ultrasound-guided ablation catheters and methods for their use. In one embodiment, a tissue ablation apparatus (2) includes a flexible elongate body (12) having proximal (14) and distal (12) ends. A plurality of spaced-apart electrodes (24) are operably attached to the flexible body near the distal end. A plurality of transducer elements (28) are disposed between at least some of the electrodes. Transducers assist the physician in determining whether or not the ablation elements are in contact with the tissue to be ablated.
(FR)
La présente invention concerne des cathéters d'ablation à guidage ultrasonique et les modalités de mise en oeuvre correspondantes. Pour un mode de réalisation de l'invention, un appareil d'ablation tissulaire (2) comporte un corps oblong flexible (12) définissant une extrémité proximale (14) et une extrémité distale. Une pluralité d'électrodes (24) disposées de place en place sont fonctionnellement fixées au corps flexible au voisinage de l'extrémité distale. Une pluralité d'éléments transducteurs (28) sont disposés entre certaines au moins des électrodes. Les transducteurs permettent au praticien de savoir si les éléments ablateurs sont ou non en contact avec les tissus à traiter.
