    摘要: A method and apparatus for ablation of cardiac tissue at a selected cardiac location is achieved by providing at least one flexible elongated guide facility having a first end, a second end, and an intermediate portion extending between the first and second ends and by providing an ablation instrument which includes at least a pair of relatively moveable clamping jaws being disposed to engage and ablate the selected cardiac location. Each guide facility is adapted for introduction into a patient's chest through an opening and for advancement to the selected cardiac location such that the intermediate portion engages the selected cardiac location and the guide facility is withdrawn through the instrument receiving passage. At least one jaw of the ablation instrument engages with the guide facility and is guided to the selected cardiac location with the aid of the guide facility to ablate the selected cardiac location.

    摘要: A surgical device has an integral first tip having pair of electrodes configured to ablate tissue using electric energy. A second tip has a pair of electrodes configured to provide pacing signals to a heart and/or to sense electrical signals passing through heart tissue. The second tip is configured to snap onto the first tip, such that the same device may be used for ablation, pacing, and sensing. Alternatively, the second tip may be integral with the device and the first tip configured to snap onto the second tip. Alternatively, a single integral tip of the surgical device may be used for ablation, pacing, and sensing. Such a multipurpose tip may comprise a plurality of electrode pairs or an array of electrodes. A user interface on the device or elsewhere may be operable to provide selectable modes for selectively varying properties of signals communicated to the electrodes.

    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.
