Multi-layer tissue patches |
| abstract |
Embodiments of the present invention encompass anti-adhesion wound dressings including patches made from amnion tissue obtained from human birth tissue. Exemplary amnion patches can be fabricated by folding a section of amnion over on itself with the epithelial layer on the outside of the folded patch and the fibroblast layer on the inside of the folded patch. Optionally, individual amnion tissue pieces can be sandwiched together to provide a multi-layer patch. Sufficient pressure is applied to the layered amnion to cause adherence between opposing faces of the fibroblast layers. The pressed fibroblast layers provide mechanical strength to hold the amnion patch together with the epithelial layers on the outsides of the amnion patch. |
