摘要: A method of applying ablation energy to achieve transmurality including applying ablation energy at a starting power to a tissue site and monitoring the impedance of the tissue site. The power applied to the tissue site can be increased in response to detection of a power plateau or application of a first power for a minimum time according to some embodiments. A power applied to the tissue site can be reduced in response to an increase in impedance according to some embodiments. Transmurality can be indicated in response to a transmurality plateau following a rise in impedance according to some embodiments.

摘要: Device, system and method for ablating tissue of a heart of a patient. The tissue is clamped between a pair of opposing jaws. A portion of the tissue is ablated at a first generally linear position on the tissue by applying ablative energy to two of a plurality of elongate electrodes, each of the two of the plurality of elongate electrodes being coupled in opposing relationship to each other and the pair of opposing jaws, respectively. An effectiveness of the ablation is sensed at a second generally linear position on the tissue with at least one of the plurality of elongate electrodes positioned on one of the pair of opposing jaws. The second linear position on the tissue is laterally distal to the first linear position on the tissue with respect to the atrium of the heart.
