Abstract
Systems and methods form curvilinear lesions in tissue within the body. The systems and methods expose tissue to electrode arrays with intersecting energy emitting elements. The systems and methods apply ablating energy for emission by the elements to create intersecting curvilinear lesion patterns in the tissue.
