ABSTRACT:
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.
