Title
(EN) TUMOR ABLATION DEVICE AND RELATED SYSTEMS AND METHODS
(FR) DISPOSITIF D'ABLATION DE TUMEURS ET SYSTÈMES ET PROCÉDÉS APPARENTÉS
Abstract
(EN)
Tumor ablation devices and related systems and methods are disclosed. Some tumor ablation devices include an RF energy delivery probe with two conductors and one or more thermocouples. The thermocouple measures a temperature at a location on one of the conductors. A generator can produce a current to be conducted between the first conductor and the second conductor via tissue within a desired ablation region. The ablation regions created by the RF energy delivery probe are symmetric about poles of the first conductor and the second conductor. A distal portion of the RF energy delivery probe may articulate, enabling a user to position the RF energy delivery probe in a proper position to ablate the tumor. The thermocouples may be disposed on a flexible or wired thermocouple circuit that is disposed between insulators.

La présente invention concerne des dispositifs d'ablation de tumeur ainsi que des procédés et des systèmes apparentés. Certains dispositifs d'ablation de tumeur comprennent une sonde de distribution d'énergie RF avec deux conducteurs et un ou plusieurs thermocouples. Le thermocouple mesure une température à un emplacement sur l'un des conducteurs. Un générateur peut produire un courant qui sera conduit entre le premier conducteur et le second conducteur par l'intermédiaire d'un tissu à l'intérieur d'une région d'ablation souhaitée. Les régions d'ablation créées par la sonde de distribution d'énergie RF sont symétriques autours des pôles du premier conducteur et du second conducteur. Une partie distale de la sonde de distribution d'énergie RF peut s'articuler, permettant à un utilisateur de positionner la sonde de distribution d'énergie RF dans une position appropriée pour réséquer la tumeur. Les thermocouples peuvent être disposés sur un circuit de thermocouple souple ou filaire qui est disposé entre les isolateurs.
