Title (EN) EXPANDABLE ELEMENTS FOR DELIVERY OF ELECTRIC FIELDS
(FR) ÉLÉMENTS EXPANSIBLES POUR L'APPLICATION DE CHAMPS ÉLECTRIQUES
Abstract:
(EN) A method, system, and device for electroporation. A system may include a medical device with a plurality of electrodes borne on an expandable element and an energy generator in communication with the electrodes. The energy generator may have processing circuitry configured to selectively deliver electroporation energy to at least one of the electrodes. The processing circuitry may determine whether an alert condition is present and, if so, cease the delivery of electroporation energy to one or more electrodes identified as the cause of the alert condition and/or prevent the delivery of electroporation energy to the one or more electrodes identified as the cause of the alert condition. The energy generator may also be configured to deliver electroporation energy in a sequence of a plurality of energy delivery patterns to enhance lesion formation.
(FR) La présente invention concerne un procédé, un système et un dispositif pour l'électroporation. Un système peut comprendre un dispositif médical muni d'une pluralité d'électrodes portées sur un élément expansible et un générateur d'énergie en communication avec les électrodes. Le générateur d'énergie peut comprendre des circuits de traitement configurés pour appliquer sélectivement de l'énergie d'électroporation à au moins une des électrodes. Le circuit de traitement peut déterminer si un état d'alerte est présent et, si tel est le cas, cesser l'application d'énergie d'électroporation à une ou plusieurs électrodes identifiées en tant que cause de l'état d'alerte et/ou empêcher l'administration d'énergie d'électroporation à la ou aux électrodes identifiées en tant que cause de l'état d'alerte. Le générateur d'énergie peut également être configuré pour appliquer l'énergie d'électroporation en une séquence d'une pluralité de modèles d'application d'énergie pour améliorer la formation de lésion.
