#$%^&*AU2017202466A120171116.pdf#####ABSTRACT OF THE DISCLOSURE An irrigated balloon catheter for use in an ostium of a pulmonary vein, includes a flex circuit electrode assembly adapted for circumferential contact with the ostium when the balloon is inflated. Adapted for both diagnostic and therapeutic applications and procedures, the balloon catheter may be used with a lasso catheter or focal catheter. The flex circuit electrode assembly includes a substrate, a contact electrode on an outer surface of the substrate, the contact electrode having a "fishbone" configuration with a ) longitudinally elongated portion and a plurality of transversal fingers, and a wiring electrode on an inner surface of the substrate, and conductive vias extending through the substrate electrically coupling the contact electrode and the writing electrodes. Microelectrodes with exclusion zones are strategically positioned relative to the electrodes. The electrodes may also be split into electrode portions. 0 51/18 c0 w ZU~ Lu (fw0 _ Lo -- QD :: I o n U 10L 0D 00 UJn0 CNC C)10 CNN CoN
