    摘要： An electrical ablation apparatus comprises first and second electrodes. Each electrode comprises a first end configured to couple an energy source and a second end configured to couple to a tissue treatment region. An energy source is coupled to the first and second electrodes. At least one electrode is movable between a first position and a second position. A first necrotic zone having a first shape is created when the electrodes are energized in the first position and a second necrotic zone having a second shape is created when the electrodes are energized in the second position. At least one electrode may be pre-formed with a radius.

    摘要： A surgical instrument, such as an endoscopic or laparoscopic instrument, includes an ablation device. The ablation device includes an elongate member comprising first and second channels. First and second probes are disposed within the respective first and second channels, where the first and second probes each define a central axis. First and second electrodes are coupled to distal ends of the respective first and second probes. A distance between the first and second electrodes is adjustable by rotating at least one of the first and second probes about the central axis of the at least one of the first and second probes.

    摘要： 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.
