Title
(EN) HIGH DENSITY MAPPING AND ABLATION CATHETER
(FR) CATHÉTER DE CARTOGRAPHIE ET D'ABLATION HAUTE DENSITÉ
Abstract
(EN)
A high density mapping and ablation catheter includes a tip electrode positioned at its distal end and a plurality of electrodes (e.g., ring electrodes, ring-segment electrodes, spot electrodes, and/or printed traces) disposed proximally of the tip electrode within the distal region. A plurality of conductors extending through the elongate catheter body to electrically connect the tip electrode and other electrodes to a source of ablation energy, an electrophysiology mapping device, and/or a programmable electric stimulator. A switching circuit can be employed, for example to enable a practitioner to selectively activate certain electrodes for ablation, for electrophysiological mapping, for pacing, or to deactivate certain electrodes entirely.
(FR)
La présente invention concerne un cathéter de cartographie et d'ablation haute densité comprenant une électrode à pointe positionnée au niveau de son extrémité distale et une pluralité d'électrodes (par exemple, des électrodes annulaires, des électrodes à segments annulaires, des électrodes ponctuelles, et/ou des tracés imprimés) disposées de manière proximale par rapport à l'électrode à pointe à l'intérieur de la région distale. Une pluralité de conducteurs s'étendant à travers le corps du cathéter allongé pour connecter électriquement l'électrode à pointe et d'autres électrodes à une source d'énergie d'ablation, un dispositif de cartographie électrophysiologique, et/ou un stimulateur électrique programmable. Un circuit de commutation peut être utilisé, par exemple, pour permettre à un praticien d'activer sélectivement certaines électrodes pour l'ablation, pour une cartographie électrophysiologique, pour une stimulation, ou pour désactiver certaines électrodes entièrement.
