Abstract
An electrical ablation apparatus including first, second, and third electrodes is disclosed. Each of the first and second electrode is configured to be selectively extended outside and selectively retracted inside a distal end of its respective lumen and is configured to diverge from its respective longitudinal axis when extended outside the distal end of its respective lumen. The third electrode is non-rotatable and is configured to be selectively extended outside and selectively retracted inside a distal end of its respective lumen. The first, second and third electrodes are extendable into a tissue treatment region to create a first necrotic zone having a first shape. At least one of the first electrode or the second electrode is selectively rotatable within its respective lumen to create a second necrotic zone having a second shape. The third electrode is configured to positionally secure the electrical ablation apparatus at the tissue treatment region.
