Cell washing plunger using centrifugal force
A method for washing a suspension of cells including a suspension fluid and a plurality of cells is provided. The method includes using centripetal force to generate a layer of wash solution against a cylindrical wall and to generate a cell suspension layer adjacent to the layer of wash solution. The method also includes forcing the cells through the layer of wash solution to generate a layer of clean cells. Devices for performing the method are also provided.
CELL PROCESSING METHOD
A method of processing blood includes receiving from a touch screen user input data for a protocol for a wash procedure. The user input data includes a numeric value. The method includes storing the protocol in a memory, receiving an identifier from a user, determining if the identifier permits the user to modify the protocol and receiving a modification of the protocol from the user. The method includes providing a plurality of authorizations, a second authorization being a default and an administrator authorization permitting the user to change a setting. The method includes comparing a password to a password stored in memory and, if there is a match, determining that the password is associated with an administrator. If a command to change the setting is received, the command is applied to change the setting. The blood is processed employing a wash procedure using the modified protocol and the changed setting.
Cell processing system and method with preliminary process evaluation
A cell processing system includes a processor connectable to a source container filled with a biological fluid, the processor including a separator configured to separate the biological fluid from the source container into at least two streams according to a process including at least one process parameter, and a controller coupled to the processor and an input. The controller is configured to receive the at least one process parameter, to evaluate the process using the at least one process parameter before performing the process, and to carry out one or more actions based on the evaluation, such as providing an output estimate to the operator, preventing the process from being performed according to a comparison between a calculated condition and a control, or providing an error indication to the operator according to the calculated condition and a measured in-process condition.
Fill and finish systems and methods for small volume processing
A system for processing fluids and filling a container with a product includes a disposable fluid circuit and reusable hardware configured to accept the disposable fluid circuit. The disposable fluid circuit includes a spinning membrane separator, first and second syringes, and a flow control cassette. The reusable hardware includes a drive coupled to the spinning membrane separator, first and second syringe pumps, the first and second syringes coupled to the first and second syringe pumps respectively, and a controller. The system also includes a syringe pump for filling low-volume containers, which syringe pump may be one of the first and second syringe pumps, or may be a third syringe pump. The syringe pump for filling low-volume containers may include a filtered vacuum/pressure source and a position detector.
System for Washing Red Blood Cells to Reduce Hemolysis
A system for washing red blood cells, comprising a separator configured to separate a quantity of blood into concentrated red blood cells having a hematocrit of at least 60% and a volume of 150-250 mL, and a supernatant component. The system comprises a flow controller configured to remove the supernatant component to provide an initial red blood cell concentrate; combine 50-500 mL of an additive solution with the red blood cell concentrate to provide an intermediate red blood cell product intended for storage for 42 days or less; and wash the intermediate red blood cell product with a washing solution.
Systems and methods for performing online extracorporeal photopheresis
Systems and methods for performing online extracorporeal photopheresis of mononuclear cells are disclosed. During a mononuclear cell collection cycle, blood is removed from a source and separated into a plasma constituent, a mononuclear cell-containing layer, and red blood cells, followed by the collection of a pre-product including at least a portion of the mononuclear cell-containing layer and at least a portion of the separated red blood cells. The mononuclear cell collection cycle may be repeated, followed by the production of a single mononuclear cell product using the collected pre-product(s). The mononuclear cell product is irradiated using a fixed dose of light, such that the mononuclear cell product is produced so as to have a predetermined volume and a predetermined hematocrit, regardless of the number of pre-products used to produce the mononuclear cell product. Following irradiation, at least a portion of the irradiated mononuclear cell product is returned to the source.
Bioprocessing system

The system further includes a disposable fluidic arrangement (100) including a centrifugal separation chamber (50) removably mountable within the compartment (215) and having one or more ports (52) allowing fluid ingress into, or egress out of the chamber, via the one or more ports in use, said ports being in fluid communication with one or more of said fluid storage vessels via fluid conduits (12, 22, 32, 42) and via one or more valve arrangement.
Blood washing and separation system
A blood washing system (20) having a rotor (22) defining an internal chamber for receiving a multi-component fluid and a skimmer assembly (24) including a moveable buoy (28) having an orifice (32) fluidly connected to an access port for the rotor for selectively withdrawing separated fractions of the multi-component fluid. The multi-component fluid can be fed into the internal chamber before the rotor (22) can be rotated at a first speed to fractionate the multi-component fluid. A brake can be applied to the rotor to slow rotation of the rotor to a slower second speed or stop rotation of the rotor causing the solid and denser fluid fractions to settle on the bottom wall (44) of the rotor (22). The buoy (28) can have a specific gravity corresponding to a selected fraction such that the buoy floats on a surface of the selected fraction, wherein the fractions floating on the selected fraction can be withdrawn through the orifice (32).
