Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 10:
11. A method, comprising:
using a switching assembly, interchangeably switching multiple electrodes, which are disposed on an expandable distal end of a catheter, between a position tracking system, an electrophysiological (EP) sensing module and a generator of an ablative power; and
using a processor, controlling the switching assembly to switch the multiple electrodes between the position tracking system, the EP sensing module, and the generator of the ablative power,
wherein when a detected impedance is indicative of an electrode of the multiple electrodes in contact with tissue, the processor is configured to switch the electrode to the generator of ablative power or the EP sensing module and the remaining electrodes of the multiple electrodes to the position tracking system; and
wherein when a detected impedance is indicative of the electrode of the multiple electrodes in contact with surrounding blood, the processor is configured to switch the electrode to the position tracking system.
