    摘要： A method and apparatus for creating transmural ablations in heart tissue, for example, may include two or more electrodes adapted to be connected to opposite poles of a bipolar RF generator so as to energize the electrodes to ablate cardiac tissue between the electrodes. A first electrode may be inserted into cardiac tissue at a first location and a second electrode may be inserted into cardiac tissue at a second location which is spaced from the first location. At least one of the electrodes may be adapted to provide a sufficiently low current density in the vicinity of the electrode to avoid substantial tissue desiccation when energized. Alternatively, the apparatus may include at least one bipolar ablation electrode which comprises an elongated conductive member of spiral shape having a pitch sufficiently small to provide sufficient surface area to avoid substantial desiccation of tissue when energized by a bipolar RF generator.

    摘要： An apparatus for transmural ablation using an instrument containing two electrodes. The electrodes extend along the surfaces of mating jaw members which are moveable between open and clamped positions. The electrodes are connected to an RF energy source so that, when activated, they are of opposite polarity. An EKG sensor is located on one of the jaw members and spaced from the electrode so that, when the electrodes are activated to form a line of ablation, the EKG sensor contacts the tissue outside the line of ablation. A pacing electrode is located on one of the jaw members so as to be on the opposite side of the line of ablation from the EKG sensor. Thus, if the line of ablation is not transmural, the EKG sensor will be able to detect signals generated by the pacing electrode.

    摘要： A method for transmural ablation using an instrument containing two electrodes or cryogenic probes. A clamping force is exerted on the two electrodes or probes such that the tissue of the hollow organ is clamped therebetween. Bipolar RF energy is then applied between the two electrodes, or the probes are cryogenically cooled, thus ablating the tissue therebetween. A monitoring device measures a suitable parameter, such as impedance or temperature, and indicates when the tissue between the electrodes has been fully ablated.

    摘要： An electrosurgical instrument system including an RF energy source that has two bipolar terminals of opposite polarity and two monopolar terminals, one being active and the other being passive. Switches are provided for selectively energizing the bipolar terminals and the monopolar terminals. The system includes an electrosurgical instrument that has two tissue-contacting members and at least two electrodes. One electrode may be associated with each of the tissue-contacting members, or both electrodes may be associated with one of the tissue-contacting members. Two conductors are provided for connecting the two electrodes to the positive and negative bipolar terminals respectively. A third conductor is provided for connecting either of the electrodes or one of the tissue-contacting members to the active monopolar terminal. The system also includes a patient return electrode pad which is in electrical communication with the pass of monopolar terminal. Consequently, the instrument may be selectively used in the either the monopolar mode or the bipolar mode by engagement of the appropriate switch. In addition, an instrument for use in such a system as disclosed, which comprises any of a variety of bipolar electrosurgical instruments, including scissors, graspers, and forceps. A separate conductor assembly is also disclosed. In a further embodiment, switching circuitry is disclosed that senses bipolar or monopolar current and automatically connects the electrosurgical instrument to contact with the leads for the sensed current.
