Techniques are provided for guidance for navigation and positioning of intravascularly delivered devices. A medical navigation system includes a delivery device comprising a catheter, an intravascularly delivered device configured to be releasably disposed in the catheter for deployment at a target site of a patient, and a navigation computer system. The intravascularly delivered device includes a plurality of electrodes including at least one indicator electrode and at least one reference electrode configured to not contact tissue when the intravascularly delivered device is deployed at the target site. The navigation computer system is configured to be electrically coupled with the plurality of electrodes. The navigation computer system controls a drive source to transmit current to the plurality of electrodes, collects electrode data corresponding to the plurality of electrodes, monitors impedance corresponding to the indicator electrode, and determines that the indicator electrode has made contact with tissue.
