Title (EN) ABLATION CATHETER, CATHETER ARRANGEMENT AND SYSTEM FOR PROVIDING ABLATIVE TREATMENT
(FR) CATHÉTER D'ABLATION, AGENCEMENT DE CATHÉTER ET SYSTÈME POUR FOURNIR UN TRAITEMENT ABLATIF
Abstract:
(EN) An ablation catheter (100) for ablative treatment of ventricular tachycardia is provided. The catheter comprises a shaft (102) which is capable of being guided to the tissue to be ablated. An ablation element (104) for ablating tissue is mounted on the shaft. The catheter further comprises a plurality of ultrasound transducer arrays (106) for obtaining images of myocardial tissue. The arrays are positioned separately from each other around the circumference of the shaft. The catheter can adopt a folded configuration and a deployed configuration. In the folded configuration, the arrays are positioned against or close to the shaft thereby facilitating insertion and guiding of the catheter. In the deployed configuration, the arrays are more separated from the shaft than in the folded configuration. Further provided is a catheter arrangement including the ablation catheter, and a system for providing ablative treatment comprising the ablation catheter or catheter arrangement.
(FR) L'invention concerne un cathéter d'ablation (100) pour le traitement ablatif de tachycardie ventriculaire. Le cathéter comprend un arbre (102) qui est apte à être guidé vers le tissu à ablater. Un élément d'ablation (104) pour l'ablation de tissu est monté sur l'arbre. Le cathéter comprend en outre une pluralité de réseaux de transducteurs ultrasonores (106) pour obtenir des images de tissu myocardique. Les réseaux sont positionnés séparément les uns des autres autour de la circonférence de l'arbre. Le cathéter comprend une configuration pliée et une configuration déployée. Dans la configuration pliée, les réseaux sont positionnés contre ou à proximité de l'arbre, facilitant ainsi l'insertion et le guidage du cathéter. Dans la configuration déployée, les réseaux sont plus séparés de l'arbre que dans la configuration pliée. L'invention concerne en outre un agencement de cathéter comprenant le cathéter d'ablation, et un système pour fournir un traitement ablatif comprenant le cathéter d'ablation ou l'agencement de cathéter.
