1. A phototherapy method, said method comprising the steps of:

  • administering a photosensitive medication to a patient, which medication fluoresces in response to light flux;

    applying energy to a proximal end of a catheter, the distal end of which is adjacent tissue of said patient, to thereby cause light flux from a distal end of said catheter, whereby said light flux causes said photosensitive medication to fluoresce; and

    generating a signal representative of one of said light flux and said fluorescence; and

    coupling said signal by way of said catheter to a location without said patient.
