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.

Abstract: Systems and associated methods form larger and deeper lesion patterns by shaping a support body with multiple electrodes (30) in ways that increase the density of the electrodes (30) per given tissue area. The support body (12) can carry either elongated, continuous electrodes (80) or arrays of non-contiguous, segmented electrodes (30).

Abstract: This invention is systems and methods to examine heart tissue morphology using three or more spaced electrodes (38), at least two of which are located within the heart in contact with endocardial tissue. The systems and methods transmit electrical current through a region of heart tissue lying between selected pairs of electrodes (224), at least one of the electrodes in each pair being located within the heart. The systems and methods derive the electrical characteristic of tissue between the electrode pairs (206) based, at least in part, upon sensing tissue impedances.
