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.
