Title
(EN) CATHETERS FOR MAPPING AND ELECTROPORATION ABLATION
(FR) CATHÉTERS POUR CARTOGRAPHIE ET ABLATION PAR ÉLECTROPORATION
Abstract
(EN) Various aspects of the present disclosure are directed toward apparatuses, systems, and methods for electroporation ablation. The electroporation catheter may include an electrode assembly comprising one or more ablation electrodes configured to generate electric fields proximate to target tissue in response to a plurality of electrical pulse sequences delivered in a plurality of therapy sections, and one or more mapping electrodes configured to measure cardiac electrical signals. In some embodiments, the measured electrical signals are used to create an electro-anatomical map.
(FR) Divers aspects de la présente invention concernent des appareils, des systèmes et des procédés d'ablation par électroporation. Le cathéter d'électroporation peut comprendre un ensemble d'électrodes comprenant une ou plusieurs électrodes d'ablation conçues pour générer des champs électriques à proximité du tissu cible en réponse à une pluralité de séquences d'impulsions électriques délivrées dans une pluralité de sections de thérapie, ainsi qu'une ou plusieurs électrodes de cartographie conçues pour mesurer des signaux électriques cardiaques. Dans certains modes de réalisation, les signaux électriques mesurés sont utilisés pour créer une carte électro-anatomique.
