Abstract
The present invention relates generally to the preparation and use of biological tissue adhesives which rely on combining fibrinogen and thrombin. More particularly, the present invention relates to a method of preparing a fibrin sealant whereby said sealant is formed by reconstituting the fibrinogen or the thrombin component in the presence of biological and/or non-biological agents such as drugs, chemicals, and proteins. Preferably, these agents are introduced in solution, such as for example, a corticosteroid-containing solution like a betamethasone solution containing betamethasone acetate or betamethasone sodium phosphate; a triamicinolone solution; or a methylprednisolone solution. These solutions may be substituted for, or provided as a complement to, other solutions that are typically used in the preparation of fibrin sealants such as, for example, calcium chloride. The invention further relates to a novel method of using the improved fibrin sealant whereby the sealant and accompanying agent(s) are delivered directly to a critical site within the body and sealed in place due to the bio-static quality of the sealant. This provides therapeutic value to patients through prolon…
