Abstract: An especially useful fibrin glue composition comprises a biocompatible, bioabsorbable hyaluronic acid derivative material, upon which are applied or chemically bonded fibrinogen and thrombin, along with other optional constituents, such as additional coagulation factors, anti-fibrinolytics, stabilizers and biologically active substances. The fibrinogen, thrombin and other components can take the form of a dry preparation, an aqueous or nonaqueous preparation, or as a combination thereof. Such a fibrin glue composition can be placed directly on a wound site and is fully reabsorbed into the body.

Abstract: A fibrin adhesive or sealant composition comprising a biocompatible, bioabsorbable hyaluronic acid material, chitin material, or chitosan material to which fibrinogen and a fibrinogen-cleaving agent are applied, along with other components such as additional coagulation factors, anti-fibrinolytics, stabilizers and biologically active substances. The fibrinogen, fibrinogen-cleaving agent and other components can take the form of dry preparation, an aqueous or nonaqueous preparation, or a combination thereof. Such a composition can be placed directly on, around, or within a wound site and is fully reabsorbed into the body.

Abstract: A system for preparing autologous plasma comprises a single use filter unit having two inlets in fluid communication with each other, an outlet, and a filtration membrane selectively permeable to blood plasma separating the inlets from the outlet. Manually operable, single use pumps, preferably syringes, connect to the inlets. A flow path is defined along the membrane between the pumps, whereby, whole blood can be repeatedly exchanged between the two pumps, past the membrane, to cause plasma to flow across the membrane and out of the outlet. A syringe can collect plasma from the outlet. Plasma thus collected can be simultaneously applied with a thrombin solution to a site on the body, thereby forming a fibrin gel.
