The present invention relates to a method for the formulation of fibrin sealant in a single delivery system. The method involves mixing a fibrinogen/Factor XIII precipitate solution with thrombin under conditions such that thrombin clotting activity is inhibited and said mixture is applied to a body site under conditions which activate the thrombin to convert fibrinogen into fibrin sealant. A single device, syringe or container can be used to apply the fibrin sealant formulation.

Why it's free to use
- Filed March 2, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 2, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 2, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
