  • Closed-loop perfusion circuit for cell and tissue cultures
    Patent number: 12312575
    Abstract: A closed-loop perfusion system may include a sealed biological culture container configured to house a biological cell culture, and a filtering unit that permits passage of waste products from an output of the sealed biological cell culture container, permits passage of nutrients from a nutrient media solution, and blocks passage of beneficial molecules from the output of the sealed biological cell culture container. The system may further include a first fluid path between an output of the sealed biological cell culture container and an input of the filtering unit, a second fluid path between an output of the filtering unit and an input of the sealed biological cell culture, and a pump to control the flow of media through the first fluid path and the second fluid path.
