Systems, methods and devices usable in the repair of a bone defect are described. A portion of a bone defect is covered with a multilayered membrane that includes a reinforcing layer. A member of the reinforcing member is fastened to an area of bone and soft tissue is secured about the membrane. The membrane facilitates healing of the defect. One membrane comprises a plurality of layers that includes a binding layer and a PTFE layer which has a textured surface and a substantially smooth surface. The textured surface provides a top surface of the membrane and the substantially smooth surface contacts bone.

Reinforced PTFE medical barriers

A medical barrier includes a sheet of unsintered substantially unexpanded hydrophilic polytetraflouroethylene (PTFE) polymer material having a density in a range of about 1.2 gm/cc to about 2.3 gm/cc, and preferably in the range of about 1.45 gm/cc to about 1.55 gm/cc, and having at least one textured surface. In accordance with one embodiment, the sheet has one textured surface and one substantially smooth surface, and has substantially uniform strength in all directions.
