Abstract

Un sistema y método para tratar el tejido del cuerpo de un paciente incluye proporcionar una fuente de alimentación acoplada al menos a un ensamble de sonda. El ensamble de sonda tiene al menos un miembro alargado con una región distal y una región proximal. La región distal tiene un dispositivo de entrega de energía eléctrica y térmicamente conductor que incluye uno o más lúmenes internos y una protuberancia eléctrica y térmicamente conductora que tiene un elemento sensible a la temperatura. El método también incluye insertar el dispositivo de entrega de energía al cuerpo de una paciente. Asimismo, el método incluye hacer emerger el dispositivo de entrega de energía por el tejido del cuerpo de una paciente. Además, el método incluye poner en circulación el fluido de enfriamiento a través de lúmenes internos a través de al menos un ensamble de bomba y entregar energía al tejido a partir de una fuente de alimentación, a través del dispositivo de entrega de energía. El método además incluye el control activo de la energía entregada al tejido al controlar una cantidad de energía entregada a través del dispositivo de entrega de energía y al controla una tasa de flujo del ensamble de bomba.
