  • Publication number: 20210016943
    Abstract: Provided is a multi-part lyophilization container for lyophilizing a fluid, storing the lyophilizate, reconstituting the lyophilizate, and infusing the reconstituted lyophilizate into a patient, including a method of using same. The container includes a front surface, a back surface, a non-breathable section including a port region, a breathable section including a breathable membrane, and an occlusion zone encompassing a boundary between the non-breathable section and the breathable section. The non-breathable section is configured to accommodate any of a liquid, a solid, a gas or combination thereof. The breathable section is configured to accommodate only a gas.

    Abstract: Provided is a multi-part lyophilization container for lyophilizing a fluid, storing the lyophilizate, reconstituting the lyophilizate, and infusing the reconstituted lyophilizate into a patient, including a method of using same. The container includes a front surface, a back surface, a non-breathable section including a port region, a breathable section including a breathable membrane, and a peelable region including a peelable seal encompassing a boundary between the non-breathable section and the breathable section. The method includes inputting a fluid into a non-breathable section of the container, freezing the fluid, applying, in a lyophilization chamber, vacuum pressure, opening the peelable seal using a pressure differential, applying heat energy, sublimating the fluid and creating a temporary occlusion in a peelable region of the container.

  • Publication number: 20200239822
    Abstract: Embodiments described herein generally provide for the expansion of cells in a cell expansion system using an active promotion of a coating agent(s) to a cell growth surface in some embodiments. A coating agent may be applied to a surface, such as the cell growth surface of a hollow fiber in a bioreactor, by controlling the movement of a fluid in which a coating agent is suspended, by changing flow rates, by changing flow directions, by rotation of the bioreactor, and/or combinations thereof.

  • Publication number: 20200239819
    Abstract: Embodiments described herein generally provide for the expansion of cells in a cell expansion system using an active promotion of a coating agent(s) to a cell growth surface. A coating agent may be applied to a surface, such as the cell growth surface of a hollow fiber, by controlling the movement of a fluid in which a coating agent is suspended. Using ultrafiltration, the fluid may be pushed through the pores of a hollow fiber from a first side, e.g., an intracapillary (IC) side, of the hollow fiber to a second side, e.g., an extracapillary (EC) side, while the coating agent is actively promoted to the surface of the hollow fiber. In so doing, the coating agent may be hydrostatically deposited onto a wall, e.g., inner wall, of the hollow fiber.
