An ablation system including a first probe extending through a first longitudinal lumen from a proximal end to beyond a distal end of a flexible shaft, a first electrode coupled to a distal end of the first probe, and a first conductor electrically coupled to the first electrode. The ablation system further includes a second probe extending through a second longitudinal lumen from the proximal end to beyond the distal end of the flexible shaft, a second electrode coupled to a distal end of the second probe, and a second conductor electrically coupled to the second electrode. The first and second probes are rotatable and translatable within the first and second longitudinal lumens respectively. Furthermore, the first electrode and the second electrode are rotatably and translatably positionable with respect to one another, via the first probe and the second probe respectively, to define a region therebetween.
