Abstract: The present relates to an autologous bioadhesive sealant composition, or fibrin glue prepared by a two-phase method, wherein all of the blood components for the bioadhesive sealant are derived from a patient to whom the bioadhesive sealant will be applied. A platelet rich plasma and a platelet poor plasma are formed by centrifuging a quantity of anticoagulated whole blood that was previously drawn from the patient. In one embodiment the platelet rich plasma is divided into two portions. In phase one, a compound that reverses the effect of the anticoagulant is added to the first portion and a clot is allowed to form. The clot is then triturated, and the resulting, serum containing autologous thrombin is collected. In phase two, the serum obtained from phase one is mixed with the second portion of the-platelet rich plasma to form the bioadhesive sealant of the invention.

Abstract: A rotatable rotor for separating components contained in a fluid, comprising an annular base having a first annular channel and an annular cover having a second annular channel for holding a flexible doughnut-shaped centrifuge bag therebetween. The cover has one or more radially spaced apart concentric indicator lines for monitoring the separation of the components. When the base and cover are superimposed, the first and second channels define an annular interior chamber having an off-centered figure eight configuration. The base and cover each comprise a grooved column axially centered and extending from the base top surface and the cover bottom surface, respectively. The flexible bag comprises inner and outer tubes extending from the core of the bag and which are seated in the column grooves to ensure that the bag is fixably rotatable with the rotor.
