ENERGY-DELIVERY DEVICE WITH FLEXIBLE FLUID-COOLED SHAFT, INFLOW/OUTFLOW JUNCTION PORTION SUITABLE FOR USE WITH SAME, AND SYSTEM INCLUDING THE SAME

摘要

PROBLEM TO BE SOLVED: To prevent damage on an antenna and prevent a bedside doctor or a patient from being injured by strengthening the entire heating pattern of the antenna by cooling the cautery probe of a microwave apparatus.SOLUTION: The energy-delivery device 100 suitable for energy delivery to tissues includes: an antenna assembly 12; a chamber defined around the antenna assembly; and a cable 15 having a proximal end suitable for junction to an electrosurgical energy source 28. The energy-delivery device also includes a flexible fluid-cooled shaft 110 coupled in fluid communication with the chamber. The flexible fluid-cooled shaft is configured to contain the length of the cable therein and configured to remove heat along the length of the cable during delivery of energy to the antenna assembly.
