= LOCAL DETECTION OF CATHETER TO TISSUE PROXIMITY WITH ENHANCED SPATIAL COVERAGE =

'''Abstract''':
a system includes a catheter, a signal generator, an interface, and a processor. the catheter includes an expandable distal-end assembly including (i) a plurality of functional electrodes that are at least partially external to an inner volume of the assembly, the functional electrodes configured to be placed in contact with wall tissue of a cardiac chamber, (ii) a proximal reference electrode located at a proximal end of the assembly externally to the inner volume, and (iii) a distal reference electrode located at a distal edge of the expandable assembly externally to the inner volume. the signal generator is configured to generate the ac signal between the proximal and distal reference electrodes. the interface is configured to sense the resulting electrical ac signal. the processor is configured to, based on the sensed ac signals, determine, for at least one given functional electrode, a proximity of the electrode to the wall tissue. #
