  • Patent number: 9028457
    Abstract: A method and apparatus for separation, concentration, and/or applying a biological or bio-engineered fluid. Generally, the fluid application device includes a sprayer body to enable the application of the fluid and a container adaptable to enable the separation of the fluid into at least a first component and a second component. The container is releasably coupled to the nozzle. The nozzle is adapted to withdraw at least one of the first component or the second component from the container after the fluid has been separated to apply the fluid to a selected site.

  • Patent number: 9011800
    Abstract: According to various embodiments, a system can be provided to separate undifferentiated cells and/or stromal cells from a whole tissue sample. The whole tissue sample can be any appropriate tissue sample obtained directly from a patient. The tissue sample can be obtained during a selected operating procedure for immediate or quick application or re-application to the patient. Accordingly, autologous cells can be obtained intraoperatively for application to a patient substantially soon after obtaining a whole tissue sample.

  • Patent number: 9011687
    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.

  • Patent number: 8998949
    Abstract: A method of conducting biological materials to soft tissue. The method includes loading a conduit device onto a delivery shaft of an inserter, inserting at least a portion of the delivery shaft into soft tissue, expelling the conduit device from the delivery shaft into the tissue, and delivering biological material through an access port of the inserter into at least one outer longitudinal channel of the conduit device.

  • Patent number: 8992862
    Abstract: A separation device including a first buoy, a second buoy, a first valve, and a second valve. The first buoy is mounted to a buoy guide post and slidably mounted within a separation chamber. The second buoy is slidably mounted to the guide post and movable between a first position and a second position. The second buoy closes the first valve and opens the second valve when in the first position. The second buoy opens the first valve and closes the second valve when in the second position. The second buoy has a density such that after spinning the device for a suitable period of time a first component of the composition is isolated between the first buoy and the second buoy and a second component of the composition is isolated between the second buoy and the end of the separation chamber that is opposite to a port.

  • Publication number: 20140356446
    Abstract: An apparatus may allow separating and collecting a fraction of a sample. The apparatus, when used with a centrifuge, allows for the creation of at least three fractions in the apparatus. It also provides for a new method of extracting the buffy coat phase from a whole blood sample and mesenchymal stem cells from bone reaming material. A buoy system that may include a first buoy portion and a second buoy 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.

  • Publication number: 20140349388
    Abstract: Disclosed is a system to separate, enrich, and/or purify a cellular population from a biological tissue, such as a tissue sample. For example, an adipose tissue sample can be acquired and disrupted. The disrupted tissue sample can then be separated and purified. The separated components can include multipotent, pluripotent, or other cell populations.

  • Patent number: 8790519
    Abstract: A method of extracting or removing a 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 separate container. The whole sample can be drier, which includes a remaining sample where excess or a selected amount of liquid is removed. Direct access to the separate container or area can then be made to provide for an efficient withdrawal of the drier material from the separation container.

  • Patent number: 8783470
    Abstract: A device for isolating a component of a multi-component composition. The device includes a housing, a chamber, and a withdrawal port. The chamber is rotatably mounted within the housing. The chamber includes a chamber base and a sidewall. The side wall extends from the chamber base. At least a portion of the sidewall is defined by a filter that permits passage of a first component of the multi-component composition out of the chamber through the filter and to the housing base. The filter restricts passage of a second component of the multi-component composition through the filter. The withdrawal port extends from a position proximate to the housing base to an exterior of the device. The withdrawal port permits the withdrawal of the first component from the housing base to an exterior of the device.
