ABSTRACT:
Systems and methods support arrays of multiple electrodes in asymmetric pattern, either radially, or axially, or both. Radial asymmetry makes it possible provide localized density of electrodes. Axial asymmetry makes it possible to locate electrodes in a pattern that closely conforms to the irregular contours of an interior body cavity, like the heart. In a preferred embodiment, the systems and methods operate the multiple electrode arrays to form continuous lesion patterns.
