  • Patent number: 11815311
    Abstract: Provided is a gas fill fixture for use in lyophilization, a related system and method. The gas fill fixture includes a chassis, fill indicator and a lid, such that the chassis and lid together form a cavity for receiving a flexible lyophilization container. The system includes a lyophilization container, a lyophilizer and a gas fill fixture incorporating a chassis, a fill indicator and a lid. The method includes process steps for using the system to lyophilize a fluid.

  • Publication number: 20230358471
    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.

  • Patent number: 11740019
    Abstract: Provided is a loading tray assembly for housing a lyophilization container and a related system and method. The loading tray assembly includes a chassis including a contact void configured to facilitate direct contact between the attached lyophilization container and a lyophilizer shelf. The method includes securing a multi-part lyophilization container including a peelable seal on a lyophilization loading tray assembly, inputting a liquid into a non-breathable section of the lyophilization container, loading the tray assembly into a lyophilizer, freezing the liquid, applying heat energy and a vacuum, the vacuum causing an opening of the peelable seal and occluding the lyophilization container to isolate the frozen liquid.
