Abstract

Systèmes et procédés perfectionnés permettant de provoquer des lésions dans des tissus humains par ablation radiofréquence. Un système générateur d'énergie R.F. est utilisé pour réguler automatiquement un niveau d'énergie R.F. fourni à une électrode déployée dans la zone de tissus à soumettre à une ablation. Cette énergie R.F. est appliquée de telle façon que la température du tissu dans ladite zone est augmentée de manière régulée jusqu'à une valeur cible sur une première période sélectionnée, puis maintenue à cette valeur cible pendant une deuxième période. Une formation de lésion maximale peut être obtenue au moyen des systèmes et des procédés selon la présente invention.
