Abstract
A cooled radio-frequency (RF) ablation probe is provided. The RF ablation probe includes a first tubular portion defining at least part of an internal cavity for circulating coolant through the cooled RF ablation probe; a second tubular portion surrounding the first tubular portion along a first portion of the length of the cooled RF ablation probe; a third tubular portion surrounding the second tubular portion along a second portion of the length of the cooled RF ablation probe; and a fourth tubular portion surrounding the third tubular portion along a third portion of the length of the cooled RF ablation probe. A gap is defined between the third tubular portion and the fourth tubular portion that can be filled with air or a vacuum can be formed in the gap to insulate one or more thermocouples attached to the fourth tubular portion from the coolant in the internal cavity.
