Abstract
A method includes monitoring impedances of the plurality of the functional electrodes relative to a reference electrode while maneuvering a catheter within a cavity of an organ, the catheter comprising (i) a shaft having a distal end, and (ii) an expandable distal-end assembly coupled to the distal end of the shaft and comprising a plurality of functional electrodes. A direction vector is estimated from the monitored impedances, along which the catheter is free to advance within the cavity of the organ without obstruction by the tissue wall. The direction vector is displayed to a user.
