Abstract
The present invention relates generally to the preparation and use of novel enhanced 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 component in the presence of various critical biological and non-biological agents. The invention further relates to a novel method of using said enhanced fibrin sealant whereby the sealant and accompanying agent are delivered directly to a critical site within the body and sealed in place due to the bio-static quality of the sealant resulting in enhanced therapeutic value derived by the prolonged presence, and optionally time-released delivery, of said accompanying agent at the critical site.
