    Abstract: A plasmapheresis system and a method for operating a plasmapheresis system are provided by which the reservoir for the concentrated red blood cells (RCC) has a first chamber for receiving anticoagulant used for priming the separator and purging the system of air prior to the initial draw cycle and a second chamber for receiving separated red blood cells. Because the entire volume of second chamber of the RCC reservoir may now receive separated red blood cells and no AC prime volume, a greater amount of whole blood may be processed in the first draw cycle, thus resulting in a greater total volume of Immunoglobulin G (IgG) being collected during the plasmapheresis procedure.

    Abstract: An irradiation device includes a processing container including a first chamber, a second chamber and at least one narrow passage in fluid communication at a first end with the first chamber and at a second end with the second chamber, and a rotatable table on which the processing container is mounted, the table having a first state wherein the first chamber is disposed at a higher elevation than the second chamber, and a second state wherein the second chamber is disposed at a higher elevation than the first chamber. The irradiation device also includes ultraviolet (UV) light source disposed proximate to the narrow passage and configured to irradiate fluid passing through the narrow passage.

    Abstract: Sterile connection systems and methods are disclosed. The systems and methods allow for connection of the facing ends of plastic tubing defining flow paths without welding or tube cutting. The two ends may be disconnected, re-sterilized and subsequently reused to make a new sterile connection.

    Abstract: A magnetic selector includes a housing configured to receive a container and having a floor upon which the container is disposed. The selector also includes a magnet carrier disposed on an opposite side of the floor from the container. The magnet carrier has at least one magnet disposed thereon and being moveable relative to the floor between a first state wherein the magnet carrier is adjacent the floor and a second state wherein the magnet carrier is spaced from the floor. The selector may include a door. The magnetic selector is usable in a fluid processing system that includes a fluid processor connectable to a source container filled with a biological fluid. A container is disposed in the magnetic selector and connected to the processor along a fluid pathway. The processor is configured to separate the biological fluid from the source container into at least two streams of material.

    Abstract: An optical detection assembly for monitoring a biological fluid in a vessel includes two fluid-adjustment structures, which are spaced apart and configured to receive at least a portion of a biological fluid-containing vessel therebetween. A light source (which may be associated with one of the fluid-adjustment structures) is configured to emit light through a thickness of the biological fluid in the vessel, while a light detector (which may be associated with the other one of the fluid-adjustment structures) is configured to receive at least a portion of the light from the light source after it has passed through the biological fluid in the vessel. At least a portion of at least one of the fluid-adjustment structures is configured to move with respect to at least a portion of the other one so as to change the thickness of the biological fluid in the monitored portion of the vessel.
