Title (EN) ABLATION MANAGEMENT
(FR) GESTION D'ABLATION
Abstract:
(EN) Apparatus for use with a blood vessel (10) of a subject includes (a) a longitudinal member (92) that has a proximal portion and a distal portion, and includes an electrode (94, 124) disposed at the distal portion, the distal portion being transluminally advanceable to the blood vessel; and (b) a control unit (100), in electrical communication with the electrode, and comprising circuitry (102). The circuitry is configured to: (a) during a dual- signal period, drive the electrode to apply a dual electric signal that has (i) an excitation component that has a frequency of 20 - 500 Hz, and (ii) an ablation component that has a frequency of 5 kHz - 1 GHz; and (b) during an ablation-signal period that is separate from the dual-signal period, drive the electrode to apply an ablation electric signal that has the ablation component but not the excitation component. Other embodiments are also described.
(FR) L'invention concerne un appareil destiné à être utilisé avec un vaisseau sanguin (10) d'un sujet, qui comprend (a) un élément longitudinal (92) qui a une partie proximale et une partie distale, et comprend une électrode (94, 124) disposée au niveau de la partie distale, la partie distale pouvant être avancée par voie transluminale vers le vaisseau sanguin ; et (b) une unité de commande (100), en communication électrique avec l'électrode, et comprenant des circuits (102). Le circuit est configuré pour : (a) pendant une période de signal double, entraîner l'électrode à appliquer un signal électrique double qui a (i) un composant d'excitation qui a une fréquence de 20 à 500 Hz, et (ii) un composant d'ablation qui a une fréquence de 5 kHz à 1 GHz ; et (b) pendant une période de signal d'ablation qui est séparée de la période de signal double, entraîner l'électrode à appliquer un signal électrique d'ablation qui a le composant d'ablation mais pas le composant d'excitation. L'invention décrit également d'autres modes de réalisation.
