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.

Abstract: Methods, apparatus, and compositions related to generating and using thrombin. Methods include preparing a solution comprising thrombin by precipitating fibrinogen from a liquid comprising whole blood or a blood fraction. Precipitated fibrinogen is removed from the liquid to form a post-precipitation liquid that is incubated with calcium and a plurality of beads to form a clot. A solution comprising thrombin is separated from the clot. Thrombin prepared thereby can be used as a tissue sealant and in methods of applying a tissue sealant to subject, including application of an autologous tissue sealant.

Abstract: Delivering a blood processing solution to blood in a blood bag includes coupling a first tube to a vented spike at one end and to a Y-shaped tube connector at a second end. An in-line microbiotic barrier filter is coupled to the first tube between its ends. A second tube is coupled to a transfer bag at one end and to the Y-shaped tube connector at its other end. A third tube is coupled to the output of the Y-shaped tube connector and sealed at its distal end. The blood bag includes a fourth tube that is sealed at a distal end. The third tube is welded to the fourth tube using a sterile tubing welder, wherein a functionally-closed, sterile flow path through which the blood processing solution can flow into the blood bag is maintained.

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.

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.

Abstract: This invention provides an apparatus and methods to consistently separate and concentrate selected blood components. The system includes, e.g., a computerized fluid handling system to transfer blood components between a centrifugal blood separation disc, containers and a concentrator.

Abstract: Methods and therapeutic compositions for treating respiratory diseases, such as chronic obstructive pulmonary disease (COPD) and devices for administering the therapeutic compositions. Methods for treatment include producing a protein solution, producing a concentrated bone marrow aspirate (cBMA), optionally combining the protein solution and cBMA to form an therapeutic composition, and optionally saturating the autologous therapeutic composition with hydrogen gas, and administering the therapeutic composition to a subject in need thereof. The present methods, compositions and devices are useful for treating COPD and the progression of COPD.

The cannulated introducer needle is curved to approximate a natural curvature of an iliac crest. The aspiration needle includes apertures for aspirating bone marrow. The aspiration needle is configured to be received in, and extend from, the cannulated introducer needle to reach a bone marrow aspiration site in the iliac crest.

Abstract: Methods and compositions generating and using an interleukin-1 receptor antagonist (IL-1ra)-rich solution. Methods for generating and isolating interleukin-1 receptor antagonist include incubating adipose tissue and/or adipocytes with polyacrylamide beads to produce interleukin-1 receptor antagonist. The interleukin-1 receptor antagonist is isolated from the polyacrylamide beads to obtain the solution rich in interleukin-1 receptor antagonist. Methods for treating a site of inflammation in a patient include administering to the site of inflammation the solution rich in interleukin-1 receptor antagonist.

Abstract: 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 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.

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.

The system includes a functionally-closed, sterile Y-type tube set.

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.

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.
