1. A system for facilitating detection of contact with targeted tissue of a subject:

  • a catheter comprising a radiofrequency electrode and a radiometer; and

    a processor configured to receive a signal from the radiometer and to provide an output indicative of contact between the radiofrequency electrode and targeted tissue of the subject based upon, at least in part, tissue properties determined from the signal received from the radiometer wherein the processor maintains the radiofrequency electrode in a deactivated condition unless contact between the radiofrequency electrode and the targeted tissue is confirmed.
