  • Patent number: 11604191
    Abstract: Disclosed herein are methods for isolating target cells from blood, involving mixing in an open container an undiluted blood sample having a volume of 10 ml or less, and binding agents, wherein each binding agent comprises (A) a primary binding agent comprising an agent capable of binding to at least one cellular epitope on target cells in the undiluted blood sample, (B) a first linker bound to the primary binding agent, to generate binding agent-attached target cells in the undiluted blood sample; contacting the binding agent-attached target cells in the undiluted blood sample with a plurality of buoyant reagents that include a second linker capable of binding to the first linker to generate an undiluted buoyant reagent-attached target cell mixture; diluting the undiluted buoyant reagent-attached target cell mixture by at least 20% to produce a diluted buoyant reagent-attached target cell mixture; applying a vectorial force, such as centrifugal force, to the diluted buoyant reagent-attached target cell mixtu

  • Patent number: 7241281
    Abstract: An apparatus and method for collecting whole blood and then separating it into components for subsequent use or storage. A self-contained bag set is used to collect the sample, which may then be placed into container adapted to fit into a centrifuge for separation of components. Each component is then sequentially extracted according to density, with a sensor present in the container to control the operation of valves directing the collection of each component. Each component may then be separated into its own storage container.

  • Patent number: 5638686
    Abstract: A device for cryoprotecting thermolabile products. A container (20) receives an annular rack (40) which is sealed by an enclosure (60). The enclosure (60) includes an outer stationary toroid (70) and a rotatable core (90). A robotic arm (160) is adapted to move and is supported by the core (90). The robotic arm (160) accesses an interior of the enclosure (60). An access portal (80) allows removal and placement of thermolabile products constrained by a holder (150). The robotic arm (160) accesses product and holder (150) and embarks upon controlled freezing of the product and its location in the rack (40) until subsequent retrieval. A computer controls the rate of freezing and stores in memory the location of all of the stored products. The robotic arm (160) reads the product in storage to assure the correct product is being accessed.

  • Patent number: 5557943
    Abstract: Rapid cooling or freezing of foodstuffs, perishables or blood products is accomplished by using a thin film membrane to totally envelope the foodstuffs or blood product only during the heat extraction period. This thin film encapsulation system closes around the item and is held tightly to the item by atmospheric and/or hydrostatic pressure. Once the item is encapsulated, low temperature heat transfer fluids are then circulated on the exterior surface of the membrane, thus extracting the heat within the item through the thickness of the membrane. Upon completion of the necessary chilling or freezing, the atmospheric and/or hydrostatic pressure is withdrawn and the chilled or frozen item is extracted.

  • Patent number: 5520885
    Abstract: An instrumentality for promulgating the cryoprecipitation of fibrinogen from a blood product. The instrumentality contemplates a container for the blood product, an apparatus for creating the fibrinogen within the container and a method of manipulating the container within the apparatus and subsequently after fibrinogen has been formed. The apparatus includes a receiver within which the container is supported, a motion transfer device for the receiver to impart motion to the container while simultaneously subjecting the container to a temperature differential to cause heat transfer. The motion imparted to the container results in a thin coating of the blood product being disposed on an interior surface of the container which, in turn, is exposed to a heat transfer fluid through the wall of the container. Successive coatings placed on an interior of the container are timed such that each coating is placed on a previous coating that has changed phase.
