The invention relates to an apparatus system and methods for treatment of virus-infected or pathogen-loaded human blood components separated from normal components comprising a separation apparatus and treatment apparatus system that inactivate pathogens in an extracorporeal body fluid system. Regarding setting up an up-stream communication session, a first Path message and a first Resv message of a RSVP protocol are detected at a designated subnet bandwidth manager in a station having a point coordinator. The floor panel has two opposing edges, each edge having a plurality of flanges for supporting engagement on the cross beams and the plurality of flanges defining a plurality of recesses between adjacent flange. The cavities occupy a volume equal to at least 28%, and preferentially at least 30%, of the volume of the supporting layer. A deflection device causes the first, second, and third drops to travel along first, second, and third paths, respectively.
