From: RF tumor ablation with internally cooled electrodes and saline infusion: what is the optimal location of the saline infusion?

Figure 2

Applicator used in the experiments to test the effect of perfusion distance. An insulated perfusion needle (arrowheads) attached to a metallic outer sheath (solid arrows) by means of two fixation systems (open arrows) and a 17-gauge internally cooled electrode with a 3 cm exposed tip (broken arrows) (A). Once the metallic outer sheath is fitted to the internally cooled electrode, the perfusion needle remains parallel and midway from the exposed tip of the internally cooled electrode (B). The bottom photo shows the case of a perfusion distance of 2 mm.
