Dual cooled radiofrequency ablation probes tethered together by electrical and fluid conduits

A cooled radiofrequency ablation probe assembly comprising:

• a first cooled radiofrequency ablation probe comprising a first electrically and thermally-conductive energy delivery device, and a second cooled radiofrequency ablation probe comprising a second electrically and thermally-conductive energy delivery device;
• cooling fluid tubing for supplying the first cooled radiofrequency ablation probe and the second cooled radiofrequency ablation probe with cooling fluid, the cooling fluid tubing comprising a connecting tubing portion extending between the first cooled radiofrequency ablation probe and the second cooled radiofrequency ablation probe such that the first cooled radio frequency ablation probe and the second cooled radiofrequency ablation probe are spaced apart by the connecting tubing portion, the connecting tubing portion ranging from 60 cm to 185 cm in length to allow heat captured by the cooling fluid in the first radiofrequency ablation probe to dissipate into the atmosphere prior to the cooling fluid entering the second radiofrequency ablation probe;
• and
• an electrical cable for supplying the first cooled radiofrequency ablation probe and the second cooled radiofrequency ablation probe with electrical energy, the electrical cable splitting to a plurality of discrete electrical cables comprising a first split electrical cable connects to the first cooled radiofrequency ablation probe and a second split electrical cable connects to the second cooled radiofrequency probe, wherein the first cooled radiofrequency ablation probe and the second cooled radiofrequency ablation probe are connected to the cooling fluid tubing in series.
