Abstract

Un appareil et des procédés destinés à l'application d'énergie à un tissu de mammifère sont décrits dans la description. Des ensembles électrodes fabriqués à partir de circuits imprimés ou souples bidimensionnels ou plats permettent une utilisation sur des structures gonflables ou extensibles, tels que des ballonnets ou des structures en maille, qui peuvent être portés au niveau de l'extrémité d'un système à base de cathéter pour administrer diverses formes d'énergie pour traiter un tissu de mammifère.
