  • Patent number: 10751464
    Abstract: Method and apparatus for removing high density particles from a biological fluid such as blood using aphaeresis. The particles are preferably sub-micron in size and denser than normally occurring components of the fluid and can be removed by a modified reverse-flow gradient density centrifuge without damaging the fluid. The particles can be provided to a patient in vivo or added to the fluid after it is removed from the patient. Some particles can carry and deliver oxygen and scavenge carbon dioxide. Other particles are conjugated to capture molecules for attaching to targets such as cancer cells, viruses, pathogens, toxins, or excess concentrations of a drug or element in the fluid. The targets are then removed from the fluid along with the particles by the aphaeresis instrument.

  • Patent number: 9956180
    Abstract: A method and apparatus for continuous removal of sub-micron sized particles and other materials attached thereto such as cancer cells and bacteria from blood and other liquids. A centrifuge rotor having a curved shape is offset on a spinning rotor base and creates contiguous areas of low to high centrifugal force depending on the distances from the axis of the rotor base. This creates a density gradient field that separates materials of different densities input to the centrifuge that exit via different outputs. A monitor detects components of the fluid that are mixed with the particles before they exit the centrifuge. If there are any unwanted components detected with the particles logic circuitry changes the speed of rotation of the rotor, and the flow rate of pumps inputting and removing separated fluid and particles to and from the centrifuge until there are no unwanted components in the fluid exiting with the particles from the centrifuge.
