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

摘要

PROBLEM TO BE SOLVED: To provide an energy-delivery device with a flexible fluid-cooled shaft, an inflow/outflow junction portion suitable for use with same, and a system including the same.SOLUTION: The energy-delivery device 10 suitable for energy delivery to tissues includes: an antenna assembly 12; a chamber defined around the antenna assembly 12; and a cable 15 having a proximal end suitable for junction to an electrosurgical energy source. The energy-delivery device 10 also includes a flexible fluid-cooled shaft 110 coupled in fluid communication with the chamber. The flexible fluid-cooled shaft 110 is configured to contain the length of the cable 15 therein and configured to remove heat along the length of the cable 15 during delivery of energy to the antenna assembly 12.
