A catheter design for ablating AF based upon the true anatomy of the left atrium and especially the left atrial pulmonary vein junction, obtained by unique imaging techniques. The catheter design will conform to the true anatomy of the anatomical structures to be ablated and takes into account the complex 3-D geometry of the left atrium and the various sizes and shapes of the pulmonary veins and their openings into the left atrium.
