ABSTRACT:
Systems and methods detect ancillary tissue within a tissue region targeted for ablation by locating a region to apply ablation energy to tissue targeted for ablation and applying energy within the region to stimulate selected ancillary tissue not targeted for ablation. The systems and methods sense when the selected ancillary tissue is affected by the stimulant energy within the region, thereby determining the presence of such ancillary tissue within the region. The systems and methods relocate the region until the selected ancillary tissue is not affected by the stimulant energy. The systems and methods then apply ablation energy in the region.
