Abstract
Anti-adhesion films useful for the prevention of surgical adhesions are disclosed. These films comprise substrate materials (such as collagen) and hetero-bifunctional anti-adhesion binding agents, wherein the substrate material is covalently linked to receptive tissue within the body of a patient via the binding agent. Preferred binding agents comprise substrate-reactive and tissue-selective functional groups. Anti-adhesion compositions useful for the formation of such films are also disclosed.
