The present invention provides multi-functional medical catheters, systems and methods for their use. In one particular embodiment, a medical catheter ( 100 ) includes a flexible elongate body ( 105 ) having a proximal end ( 110 ) and a distal end ( 120 ). A plurality of spaced apart electrodes ( 130 - 136 ) are operably attached to the flexible body near the distal end. At least some of the electrodes are adapted for mapping a tissue and, in some embodiments, at least one of the electrodes is adapted for ablating a desired portion of the tissue. The catheter includes a plurality of tissue orientation detectors ( 140 - 146 ) disposed between at least some of the electrodes. In this manner, the medical catheter is capable of tissue mapping, tissue imaging, tissue orientation, and/or tissue treatment functions.
