Title
(EN) A CATHETER FOR OPEN-LOOP IRRIGATED ABLATION OF TISSUE
(FR) CATHÉTER POUR L'ABLATION DE TISSU AVEC IRRIGATION EN BOUCLE OUVERTE
Abstract
(EN)
The present invention relates to a catheter (20) adapted for open-loop irrigated ablation, such as RF ablation, of a tissue (40). Said catheter has a distal tip (22) with an ablation entity (15) adapted for performing ablation of the tissue, an irrigation hole (21) and an ultrasound transducer (5) adapted for transmitting and/or receiving ultrasonic waves. The ultrasound transducer is disposed behind or in the irrigation hole of the catheter, so as to allow an irrigation fluid to flow out of the irrigation hole, and so as to allow transmitting and/or receiving the ultrasonic waves through the irrigation hole. The invention also relates to an imaging system and to a corresponding method for operating a catheter.
(FR)
La présente invention concerne un cathéter (20) adapté pour l'ablation irriguée en boucle ouverte, telle que l'ablation RF, d'un tissu (40). Ledit cathéter a une extrémité distale (22) avec une entité d'ablation (15) adaptée pour effectuer l'ablation de tissu, un trou d'irrigation (21) et une sonde à ultrasons (5) adaptée pour émettre et/ou recevoir des ondes ultrasoniques. La sonde à ultrasons est disposée derrière ou dans le trou d'irrigation du cathéter, de manière à permettre qu'un fluide d'irrigation s'écoule du trou d'irrigation, et de manière à permettre d'émettre et/ou de recevoir les ondes ultrasoniques par l'intermédiaire du trou d'irrigation. L'invention concerne en outre un système d'imagerie et un procédé correspondant pour actionner un cathéter.
