Abstract: Devices, systems, and methods for obtaining one or more desired fluid components, using a back-flushable filter device comprising a filter and at least one diffusing plate, are disclosed.

Abstract: Devices, methods, and systems for obtaining one or more biological fluid components, and reducing red blood cell contamination, using a back-flushable filter device, are disclosed.

Abstract: A method of making a sterile connection comprises mating a first fitting having an aperture and a second fitting having an aperture, removing first and second strip out layers from between the end surfaces of sealed first and second resilient sealing members, and contacting the end surfaces of the resilient sealing members to provide fluid communication between the aperture of the first fitting and the aperture of the second fitting. A connector assembly comprises first and second fittings, a stem mounted for axial movement through the first fitting into the second fitting, and a deformable locking device which selectively prevents axial movement of the stem in the first fitting.

Abstract: A connector assembly and a fluid system or device comprises a connector assembly which includes first and second fittings, each fitting having an aperture, a first cap, and a stem disposed in the aperture of the first fitting. In various embodiments of the invention, the connector assembly further comprises a socket cooperatively arranged with one of the first and second fittings and at least one resilient sealing member. A method for making a connection includes removing a cap, mating first and second fittings, removing a stripout layer, and establishing a fluid flowpath through the first and second fittings.

Abstract: A connector or a connector assembly comprises a fitting, a resilient sealing member, a plurality of protrusions, and a removable stripout layer. The fitting includes a socket. The protrusions extend from the fitting and are connectable to a mating connector. The resilient sealing layer, which is disposed in the socket of the fitting, includes a hollow body having opposite open ends and an internal passage extending between the open ends. The removable stripout layer is movable between a first position in which the stripout layer overlies an end of the resilient sealing member and a second position in which the stripout layer is removed from the end of the resilient sealing member.

Abstract: Devices, systems and methods for treating a biological fluid are provided comprising placing the fluid in contact with a complement filter capable of depleting at least one complement fragment from the fluid while at least one component of the biological fluid is being stored.

Abstract: A connector assembly and a fluid system or device comprise a connector assembly which includes first and second fittings, each fitting having an aperture, and a stem disposed in the aperture of the first fitting. In various embodiments of the invention, the connector assembly may further comprise a socket cooperatively arranged with one of the first and second fittings, at least one resilient sealing member, a sealing layer joined to the socket or covering the resilient sealing member, and/or a deformable locking device. A method for making a connection includes mating a first fitting having an aperture and a second fitting having an aperture without fluid within the first and second fittings, establishing a fluid flowpath through the first and second fittings by advancing a stem having a head through the aperture of the first fitting into the aperture of the second fitting, and establishing fluid flow through the first and second fittings by opening a fluid blocking mechanism.

Abstract: A method for processing a biological fluid comprises the steps of collecting platelet-rich plasma (PRP) in a container containing a complement filter, centrifuging the PRP in the container to provide a supernatant layer comprising a volume of platelet-poor plasma (PPP) and a sediment layer including concentrated platelets, passing most of the volume of the PPP from the container, suspending the platelets in the remaining volume of PPP to provide a platelet suspension and storing the platelet suspension in the container for a storage period of at least about 24 hours while contacting the complement filter with at least a portion of the platelet suspension and removing complement from the platelet suspension.

Abstract: A device (100) such as a drip chamber that can be filled to a predetermined level is disclosed. The device comprises a housing (14) and a porous medium (10), wherein the porous medium allows gas to pass therethrough.

Abstract: A biological fluid filter assembly (100) including a plurality of porous media (6a, 6b) and essentially lacking a solid partition between the media is disclosed. Preferably, the assembly has a space (12) between the media (6a, 6b). The filter assembly is especially suitable for depicting leukocytes from a biological fluid such as packed red cells, and can be used to deplete leukocyts from two or more units of biological fluid. A method of using the filter assembly is also provided.
