Abstract

Systems and associated methods position arrays of multiple emitters of ablating energy (30) in straight or curvilinear positions in contact with tissue to form elongated lesion patterns (200)-(206). The elongated lesion patterns can be continuous (200, 204) or interrupted (202, 206), depending upon the orientation of the energy emitters.
