Title
(EN) ABLATION CATHETER WITH ELECTRODES
(FR) CATHÉTER D'ABLATION DOTÉ D'ÉLECTRODES
Abstract
(EN) A catheter configured to deliver therapeutic energy to a tissue can include can include an elongate shaft extending along a shaft longitudinal axis and comprising a shaft proximal end and a shaft distal end. The catheter can include a flexible tip assembly comprising a tip assembly outer surface, wherein the flexible tip assembly is connected to the shaft distal end and is configured to deliver therapeutic energy to the tissue, and wherein the flexible tip assembly further includes. The flexible tip assembly can include an insulative layer comprising an insulative layer outer surface, wherein the insulative layer is disposed on the tip assembly outer surface and a mapping electrode disposed on the insulative layer outer surface.
(FR) L'invention concerne un cathéter configuré pour délivrer de l'énergie thérapeutique à un tissu, lequel cathéter peut comprendre une tige allongée s'étendant le long d'un axe longitudinal de tige et comprenant une extrémité proximale de tige et une extrémité distale de tige. Le cathéter peut comprendre un ensemble pointe souple comprenant une surface externe d'ensemble pointe, l'ensemble pointe souple étant relié à l'extrémité distale de tige et étant configuré pour délivrer de l'énergie thérapeutique au tissu, et l'ensemble pointe souple comprenant en outre : une couche isolante comprenant une surface externe de couche isolante, la couche isolante étant disposée sur la surface externe d'ensemble pointe, et une électrode de mappage disposée sur la surface externe de couche isolante.
