Disclosed is a specially treated sheet of amnion, such as an amniotic membrane which prevents adhesions following injury, such as surgical injury and prevents bleeding of internal organs caused by injury. The amniotic sheet has its cellular monolayer removed exposing basement membrane, collagen types I, II, III, laminin, fibronectins, and other glycoprotein components which promote wound healing and remove antigenic sites in the cellular layer which may elicit an immune response. The amniotic material is sterilized and may be cross-linked. It is applied as a single layer to an injured surface subject to adhesions or wrapped on internal organs subject to bleeding, and can be sutured or applied by a liquid anti-adhesive adjuvant. The graft can be applied to a wet as well as a dry surface. |
