20090221075 | System And Process For Separating A Material - 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. | 09-03-2009 |
20120027746 | METHOD FOR GENERATING THROMBIN - 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. | 02-02-2012 |
20120230890 | Method and Apparatus for Isolating Platelets From Blood - A platelet collection device comprising a centrifugal spin-separator container with a cavity having a longitudinal inner surface. A float in the cavity has a base, a platelet collection surface above the base, an outer surface. The float density is below the density of erythrocytes and above the density of plasma. The platelet collection surface has a position on the float which places it below the level of platelets when the float is suspended in separated blood. During centrifugation, a layer of platelets or buffy coat collects closely adjacent the platelet collection surface. Movement of a float having a density greater than whole blood through the sedimenting erythrocytes releases entrapped platelets, increasing the platelet yield. | 09-13-2012 |

20140107561 | COMPRESSIVE OXYGEN DIFFUSIVE WOUND DRESSINGS - 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. | 04-17-2014 |
