Method for preparing thrombin for use in a biological glue
InactiveUS6472162B1Derive fast acting, stable autologous thrombinSimple preparatory procedureBioreactor/fermenter combinationsBiological substance pretreatmentsTissue sealantDonors plasma
A sterile method for preparing stable thrombin component from a single donor's plasma in which the thrombin component and the clotting and adhesive proteins component are harvested simultaneously from the same donor plasma in less than one hour. The combined components provide an improved biological hemostatic agent and tissue sealant by virtue of its freedom from the risk of contaminating viruses or bacteria from allogenic human or bovine blood sources. The thrombin provides polymerization of the clotting and adhesive proteins in less than five seconds, and is sufficiently stable to provide that fast clotting over a six hour period. Further, the clotting times can be predictably lengthened by diluting the thrombin with saline.
