Abstract

Se proporciona un dispositivo electroquirúrgico que incluye una sonda que se extiende en un dispositivo electroquirúrgico y que tiene una región proximal y una región distal. Un diámetro interno de la sonda define un lumen. La sonda tiene una porción eléctricamente aislada que se extiende desde la región proximal hasta la región proximal y una porción conductora eléctricamente expuesta ubicada en la región distal. La porción conductora eléctricamente expuesta entrega energía de radiofrecuencia a un área del tejido adyacente a la región distal. El dispositivo también incluye un sistema de transferencia del calor para eliminar energía térmica del área del tejido que está en contacto térmico con el área del tejido. El sistema de transferencia del calor elimina desde aproximadamente 0.1 Watts hasta aproximadamente 50 Watts de energía del tejido. Además, el sistema de transferencia del calor puede alejar el calor lo suficiente del tejido sin el uso de una bomba peristáltica para circular un líquido dentro del lumen.
