The occlusion apparatus may be adapted for use in a deployment device having a pair of jaws and optionally having a respective pair of shuttle bodies for releasably connecting an occlusion apparatus to the jaws while in an open position and for releasing the occlusion device from the jaws while in a closed position. A system for occluding an anatomical structure is also disclosed that includes an occlusion apparatus and a deployment device for holding the occlusion apparatus in an open position for locating the occlusion device adjacent the anatomical structure to be occluded and then moving the occlusion apparatus to a closed position and locking the occlusion apparatus in the closed position.

Abstract: A method and apparatus 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. The method provides for ablating cardiac tissue of a patient utilizing a sub-xyphoid approach and identifying cardiac tissue prior to ablation.

Abstract: 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.

Abstract: 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.
