Abstract
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.
