  • Patent number: 10888878
    Abstract: An apparatus for manipulating particles includes: a rotor rotatable at a speed about an axis, the rotor having an outer periphery and front and rear opposite sides; at least one chamber mounted on the rotor, each chamber having an inlet and an outlet; an umbilical assembly rotatable about the axis; and a drive mechanism configured to rotate the umbilical assembly at about one-half the speed of the rotor. The umbilical assembly includes: a curvilinear guide tube connecting to a drum at the rear side of the rotor; a flexible conduit residing in the guide tube; and first and second elongate passageways for each chamber extending through the conduit, wherein the first passageway is in fluid communication with the inlet of a respective chamber and the second passageway is in fluid communication with the outlet of the respective chamber. The passageways are held in a spaced-apart relationship relative to one another.

  • Patent number: 10208283
    Abstract: The present invention comprises methods and systems for manipulation of media and particles, whether inert materials or biomaterials, such as cells in suspension cell culture. The methods and systems comprise use of an apparatus comprising a rotating chamber wherein the actions of the combined forces of gravity, fluid flow force and centrifugal force form a fluidized bed within the rotating chamber.

  • Publication number: 20050266548
    Abstract: The invention comprises novel culture methods and devices in which biocatalysts are substantially immobilized contained, suspended and/or incubated in a chamber. At least one injection element provides a fluid flow to a perimeter of the chamber and the fluid force of the fluids flowing into the chamber works with the centripetal force created by rotation of the device to suspend the cells within the chamber, promote cell growth and/or clean the fluid as it passes thru the suspended biocatalyst. Other embodiments are also claimed and described.
