Claim 13:
14. A system for use with a medical device having a plurality of electrodes and configured for insertion within a patient, the system comprising:
a signal generator configured to apply a plurality of drive signals across different pairs of electrodes of the medical device;
a measurement circuit configured to measure responses of the plurality of electrodes to the drive signals and generate an impedance value for each of the plurality of electrodes of the medical device; and
a contact assessment module configured to, for each electrode, determine a contact status of each of the plurality of electrodes with adjacent tissue based on the generated impedance value associated with each electrode, wherein the contact assessment module is further configured to modify the contact status of one or more of the plurality of electrodes based, at least, in part, on the contact status of one or more neighboring electrodes.
