A method of forming and preserving a bioremodelable, biopolymer scaffold material by subjecting animal tissue to chemical and mechanical processing. In addition to skin tissue, another source of EBM is a blood vessel. EBM may be used for hernia repair, colon, rectal, vaginal and or urethral prolapse treatment; pelvic floor reconstruction; muscle flap reinforcement; lung tissue support; rotator cuff repair or replacement; periosteum replacement; dura repair; pericardial membrane repair; soft tissue augmentation; intervertebral disk repair; and periodontal repair. EBM may also be used as a urethral sling, laminectomy barrier or spinal fusion device.

EB matrix production from animal tissue and its use for tissue repair

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.

Processing tissue to produce a biopolymer scaffold for tissue engineering

A method of forming and preserving a bioremodelable, biopolymer scaffold material is carried out by subjecting animal tissue, particularly fetal or neo-natal tissue, to chemical and mechanical processing. The process may include, but is not limited to, harvesting the tissue, optionally extracting growth and differentiation factors from the tissue, inactivating infective agents of the tissue such as by treating with KOH or NaOH, mechanically expressing undesirable components from the tissue, delipidizing the tissue with organic solvents, mechanically expressing components released by the solvet, washing the tissue, optionally drying the tissue, and optionally cross-linking the tissue, not necessarily in the order described. The resulting product, named EB Matrix (EBM), is characterized by its microbial, fungal, viral and prion inactivated state. EBM is strong, bioremodelable, drapable and does not undergo calcification.
