Automated device and method to purify biomaterials from a mixture by using magnetic particles and disposable product-contact materials
This invention relates to a device and method of using the device for purification that separates material of interest from contaminating materials using non-porous magnetic particles and single-use or disposable materials that come in contact with the material of interest. The process encompasses multiple cycles in a single batch to reduce the cost of magnetic particles. This method can be executed in a fully automated manner by a controller that manages different inputs and outputs of system hardware.
Composite fluid separation
Embodiments are described that include systems and methods for separating components of a composite fluid, e.g., whole blood. Some embodiments provide for processing a composite fluid by subjecting a volume of the fluid to a first centripetal acceleration for an initial separation, followed by a second centripetal acceleration for a second separation.
DEVICES AND METHODS FOR MAKING THERAPEUTIC FLUIDS
Devices and methods for extracting and concentrating therapeutically active factors from mammalian fluids and tissues are described herein.
System and method for collecting plasma
A method for collecting plasma includes determining the weight and hematocrit of a donor, and inserting a venous-access device into the donor. The method then withdraws blood from the donor through a draw line connected to a blood component separation device, and introduces anticoagulant into the withdrawn blood. The blood component separation device separates the blood into a plasma component and a second blood component, and the plasma component is collected from the blood component separation device and into a plasma collection container. The method may then calculate (1) a percentage of anticoagulant in the collected plasma component, and (2) a volume of pure plasma collected within the plasma collection container. The volume of pure plasma may be based, at least in part, on the calculated percentage of anticoagulant. The method may continue until a target volume of pure plasma is collected within the plasma collection container.
Multilayered blood product
A blood product (10), a method for preparing the blood product, a blood product obtainable by the method and a blood product preparing container means. The blood product comprises components from whole blood, especially fibrin, thrombocytes and leukocytes. The blood product (10) comprises a first layer (21), a second layer (22) and a third layer (23). The second layer (22) is adjacent to the first layer (21) and the third layer (23). The first layer (21) defines a first outer surface (24) of the blood product (10) and the third layer (23) defining a second outer surface (25) of the blood product (10). The first layer (21) comprises a majority of fibrin, the second layer (22) comprises a majority of thrombocytes and the third layer (23) comprises a majority of leukocytes.

Fat filtration device
A device for filtration of fat extracted during liposuction procedures. The device includes: a first reservoir filled with a physiological solution adapted to be suctioned by a syringe containing fat mixed with blood and anesthetic; a second reservoir, empty, intended to receive cyclically from the syringe a liquid mixture consisting of the suctioned solution, blood and anesthetic separated from the fat; and at least one filter element provided with a connection member for connection of the syringe, the filter element being connected to the first reservoir and the second reservoir through a three-way connector. A first one-way valve configured to allow passage of a flow of fluid from the first reservoir towards the connector is arranged on a branch of the connector connected to the first reservoir. A second one-way valve configured to allow passage of a flow of fluid from the connector towards the second reservoir is arranged on a branch of the connector connected to the second reservoir.
DEVICE FOR EXTRACTING PLATELET RICH PLASMA
The present invention relates to a platelet rich plasma (PRP) extracting device and extracting method using the same, and more particularly, to a platelet rich plasma (PRP) extracting device capable of quickly and effectively extracting the highly concentrated PRP from centrifuged blood by a simple manipulation.
PLATELET RICH PLASMA SEPARATION KIT
The present invention discloses a sterile PRP separation kit that has compartmentalized container having a cover that allows for a stage-specific exposure of sterile components of the sterile PRP separation kit housed within stage-specific compartments to a non-sterile environment commensurate with a specific stage of operation of a separation process of PRP. The sterile PRP separation kit includes a PRP tube with segregated portals for injection of blood into the PRP tube, aspiration of PRP from the PRP tube, and for maintaining an interior pressure of the PRP tube at equilibrium with ambient pressure during both injection and aspiration.
