Abstract
An electrical ablation apparatus includes a housing extending along a longitudinal axis. A first electrode and a second electrode are disposed within the housing. The electrodes are configured to connect to electrically conductive wires. The first and second electrodes are separated by a gap. The second electrode includes first and second prongs defining an opening suitable to receive tissue to be ablated therebetween. When the first and second electrodes are energized at a predetermined energy level, an electric current suitable to ablate the tissue flows across the gap and forms an electric arc between the distal end of the first electrode and the tissue. A system includes an energy source to drive the electrical ablation apparatus. A method includes introducing the electrical ablation apparatus into a patient and ablating tissue with the electric arc.
