The clamp has an elongate shaft having a major axis, first and second opposing jaws configured to open and close along a first plane, a first and second ablation element positioned along the first and second jaws configured to ablate the tissue positioned therebetween, an actuable joint operatively coupled between the shaft and the opposing jaws and configured to move the opposing jaws to a selectable angle relative to the major axis of the elongate shaft along a second plane orthogonal to the first plane. The ablation clamp has a handle operatively coupled to the shaft having an actuator configured to actuate the actuable joint and a trigger mechanism to open and close the opposing jaws.

摘要： A system and method for creating lesions and assessing their completeness or transmurality. Assessment of transmurality of a lesion is accomplished by monitoring the impedance of the tissue to be ablated. Rather than attempting to detect a desired drop or a desired increase impedance, completeness of a lesion is detected in response to the measured impedance remaining at a stable level for a desired period of time, referred to as an impedance plateau. The mechanism for determining transmurality of lesions adjacent individual electrodes or pairs may be used to deactivate individual electrodes or electrode pairs, when the lesions in tissue adjacent these individual electrodes or electrode pairs are complete, to create an essentially uniform lesion along the line of electrodes or electrode pairs, regardless of differences in tissue thickness adjacent the individual electrodes or electrode pairs.
