a method of forming and preserving a bioremodelable , biopolymer scaffold material by subjecting animal tissue , particularly fetal or neo - natal tissue , to chemical and mechanical processing . the process includes , but is not limited to , harvesting the tissue , optionally extracting growth and differentiation factors from the tissue , inactivating infective agents of the tissue , mechanically expressing undesirable components from the tissue , delipidizing the tissue , washing the tissue , optionally drying the tissue , optionally cross - linking the tissue not necessarily in the order described . the resulting product , ebm , is characterized by its microbial , fungal , viral and prion inactivated state . ebm is strong , bioremodelable , drapable and does not undergo calcification . ebm supplants previous inventions because of its unique method of preparation and broad applicability in tissue reengineering .
