  • Publication number: 20140154234
    Abstract: Methods of generating thrombin and methods of applying a clotting tissue sealant to a site on a subject are provided. A blood component comprising platelets can be obtained from the subject. A hypotonic composition is contacted with a solid matrix to form a thrombin-containing liquid, where the hypotonic composition includes water, calcium, a blood component comprising platelets, and optionally a chelator. Calcium is present in the hypotonic composition in an amount greater than the amount of calcium that can be complexed by the chelator. Thrombin-containing liquid is then separated from the hypotonic composition and can be applied to the site on the subject to form a clot, for example, by combination with fibrinogen.

  • Publication number: 20140107561
    Abstract: Oxygen diffusive wound dressings and methods of manufacturing and use are described herein. The wound dressing may generally provide a ready supply of oxygen to a wound being treated via one or more oxygen conduits which are designed to pass oxygen from ambient air or other oxygen reservoirs into proximity to the wound, and may also provide for exudate removal through transecting channels in fluid communication with both the wound surface and a hydrophilic absorbent material.

  • Publication number: 20140097135
    Abstract: Disclosed is an apparatus that allows for separating and collecting a fraction of a sample. The apparatus, when used with a centrifuge, allows for the creation of at various fractions in the apparatus. A buoy system that may include a first buoy portion and a second member operably interconnected may be used to form at least three fractions from a sample during a substantially single centrifugation process. Therefore, the separation of various fractions may be substantially quick and efficient. Also selected fractions from the sample can be applied to a patient, either alone or as part of a mixture.

  • Publication number: 20140091048
    Abstract: A separator system operable to use centrifugation to fractionate a multiple component material, such as a suspension including blood, comprises a buoy. The buoy can be carried in a separation container and has a tuned density that is configured to reach an equilibrium position in the multiple component material. A guide surface is carried on a buoy upper surface and is inclined to an accumulation position near a buoy perimeter. The buoy suspension fractionation system can be used in a method of isolating a fraction from a suspension, and in a method for re-suspending particulates for withdrawal.

  • Publication number: 20140088492
    Abstract: A separation system for separating a multiple component material into at least two fractions. The separation system includes a separation device having a first end, a second end opposite to the first end, and a sidewall that extends between the first end and the second end to define a separation chamber having an interior volume. The system also includes a valve moveable between an open position and a closed position, the valve is mounted at a fixed location within the separation chamber at a position that is closer to the second end than to the first end and is spaced apart from the second end, the valve is operable to isolate a first fraction of the multiple component material having a first density on a first side of the valve from a second fraction having a second density on a second side of the valve that is opposite to the first side.

  • Publication number: 20140071787
    Abstract: A clotting serum production device including a main chamber, an inlet housing, and an outlet port. The main chamber is defined by a first end wall, a second end wall opposite to the first end wall, and a side wall extending between the first end wall and the second end wall. The inlet housing extends from the first end wall. The inlet housing includes a first inlet port, a second inlet port, and a first conduit extending between the first inlet port and a second conduit. The second conduit extends between the second inlet port and the main chamber. The inlet housing is configured to provide one-way fluid flow from the first inlet port to the second inlet port and to provide one-way fluid flow from the second inlet port to the main chamber. An outlet port is in fluid communication with the main chamber and provides fluid communication with an exterior of the clotting serum production device.

  • Publication number: 20140034567
    Abstract: A method and apparatus for obtaining various components of a multi-component material. Generally, a component of a whole blood sample may be concentrated from a patient and re-introduced to the same patient. For example, a clotting component, such as thrombin, from a whole blood sample may be extracted and concentrated in an apparatus and collection to be reapplied or reintroduced into a patient.

  • Publication number: 20140021147
    Abstract: Extracting or removing at least a portion of liquid phase from a whole sample using a centrifugal force is disclosed. Centrifugal forces are used to apply pressure to a whole sample and drive a liquid phase through a passage region that can be perforated and/or porous and maintain a drier portion within a separation container. The whole sample can be dried, which includes a remaining sample where excess or a selected amount of liquid is removed. Direct access to the separation container or area can then be made to provide for an efficient withdrawal of the drier material from the separation container.

  • Patent number: 8586324
    Abstract: A method for preparing and isolating clotting serum. The method includes adding reagent and a clotting serum source to a reaction chamber of a clotting serum production device that includes an activator. The reagent, clotting serum source and activator are mixed by shaking the serum production device to bring the contents to a foam. The serum production device is placed in either a vacuum or at room temperature for a period of time, and the clotting serum is extracted from the reaction chamber.
