Abstract
Authentication and verification of suitability for use of disposable elements can be made by evaluation of characteristic data stored on a non-volatile read/write memory element, especially useful in a photoactivatable agent patient treatment system wherein photoactivatable agents, in contact with patient blood cells, are irradiated extracorporeally and then returned to the patient.
