Fixation devices for tissue repair, for example sutures, surgical arrows, staples, darts, bolts, screws, buttons, anchors, nails, rivets, or barbed devices comprise at least one of angiogenic material; angiogenic precursor material which is capable of breaking down in vivo to form angiogenic material; or tissue-engineered material, which tissue-engineered material is capable of producing angiogenic material. In a preferred form, the material is incorporated into a polymer matrix having predetermined hydrophobicity to allow controlled release of angiogenic materials such as butyric or hydroxybutyric acid or salts thereof. Polymer matrix compositions comprising angiogenic materials and methods for tissue repair are also provided.

A wound dressing which comprises a carrier layer having a non-adherent to cell layer on a wound facing surface thereof. The non-adherent layer has bonded thereto a biodegradable cell anchoring layer which anchors mammalian cells. In use, the degradable layer breaks down releasing the cells into the wound site which are discouraged from reattaching to the dressing by the non-adherent layer. Thus the dressing can switch from a cell binding state to a state in which the binding of cells is discouraged. Systems, methods of treatment and methods of manufacturing the dressing are also disclosed.
