摘要： A surgical instrument includes an ablation device. The ablation device includes an elongated flexible member having a proximal end and a distal end. The flexible member includes first and second lumens. A first needle electrode is configured to slideably move within the first lumen. A second needle electrode is located within the second lumen. The first and second needle electrodes are adapted to couple to an electrical waveform generator and to receive an electrical waveform sufficient to electrically ablate tissue located between the first and second needle electrodes.
