Title
(DE) VORRICHTUNG ZUR LOKALISIERUNG EINES ELEKTRISCHEN FELDES
(EN) APPARATUS FOR LOCALISING AN ELECTRICAL FIELD
(FR) APPAREIL POUR LOCALISER UN CHAMP ÉLECTRIQUE
Abstract
(EN)
An apparatus for localising an electrical field for electroporation of abluminal tissue such as ganglionated plexi is provided comprising a pulsed DC electrical power supply and at least two catheters. Each catheter includes at least one catheter tip and electrode assembly configured for endocardial placement such that the electrodes are positionable at separate endocardial locations and allow development of an electrical field between the electrodes to effect electroporation of the abluminal tissue in the electrical field.

(FR)
La présente invention concerne un appareil pour localiser un champ électrique pour l’électroporation d’un tissu abluminal, tel que des plexus ganglionnaires, comprenant une alimentation électrique CC pulsée et au moins deux cathéters. Chaque cathéter comprend au moins un embout de cathéter et un ensemble d’électrodes configuré pour un placement endocardiaque de sorte que les électrodes puissent être positionnées à des emplacements endocardiaques séparés et permettent le développement d’un champ électrique entre les électrodes pour effectuer une électroporation du tissu abluminal dans le champ électrique.
