Abstract: A device and method for forming fibrin foam, preferably utilizing a single container, comprising a base structured to be rotationally driven and including a separation chamber disposed and structured to receive a blood sample therein. The base includes a reaction chamber disposed in fluid communication with said separation chamber. The blood sample is separated into a plasma segment and a packed cell segment when subjected to sufficient centrifugation concurrent to the driven rotation of the base. According to structural features, and in some instances concurrent and continuous centrifugation, the plasma segment is directed from said separation chamber into said reaction chamber which includes sufficient quantities of gas and reactant composition to facilitate formation of fibrin foam therein concurrent to centrifugation.

Abstract: The present invention is a specially prepared fibrin foam, and a method of (and equipment for) making it, which is flexible, contains either open cells, closed cells or both, and having individual cell diameters between 0.001 and 2 mm. Typical ratios of reactants, to give the desired foam characteristics, include 50 cc (45-55 cc) of whole blood (prior to separation to the plasma component) with the subsequent addition thereto of 2 ml (1.5-2.5 ml) 3% hydrogen peroxide, 5000 units (4500-5500 units) thrombin and 1 gm (0.9-1.1 g) calcium chloride in 3 cc (2-4 cc) water. The present invention also includes specialty vessels and constructs, namely, automated, or semi-automated inner containers for the non-blood reactants, and a custom outer separation vessel having a punted based with an annular base lip as well as an upper tube shape tapering inward towards its top annular opening.

Abstract: A system for forming fibrin foam, preferably utilizing a single container, comprising a cartridge structured to be rotationally driven and including a primary chamber disposed and structured to receive a blood sample therein. The cartridge further includes reaction and cell chambers independently disposed in fluid communication with said primary chamber. The blood sample is separated into a plasma segment and a packed cell segment when subjected to sufficient centrifugation concurrent to the driven rotation of the cartridge. Concurrent to the centrifugation of the canister, the plasma segment is directed from said primary chamber into said reaction chamber and the packed cell segment is directed from an interior of said primary chamber to an exterior thereof, such as into the cell chamber. The reaction chamber includes sufficient quantities of gas and reactant composition to facilitate formation of fibrin foam therein concurrent to centrifugation.
