1. A method or use, comprising:
selectively positioning an ablation catheter system at a treatment site comprising cardiac tissue;
ablating cardiac tissue at the treatment site with the ablation catheter system using a power setting of approximately 90W applied to tissue for a first ablation time of approximately four (4) seconds to achieve a first maximum tissue temperature;
ceasing ablation for a break period of approximately 4 seconds immediately following the first ablation time;
ablating, immediately after the break period of approximately 4 seconds and using the power setting of approximately 90W applied to the cardiac tissue for a second ablation time of approximately 4 seconds, the cardiac tissue at the treatment site with the ablation catheter system to achieve a second maximum tissue temperature; and
achieving approximately zero incidence of steam pop occurrence in both left and right atrial ablations and complete pulmonary vein isolation, by the ablation catheter system, for all patients of a predetermined patient population suffering from PAF.
