Abstract: A formulation for generating an adhesion barrier that includes a plurality of particles or a dry powder that is made of a polymer combination of at least one biodegradable polymer and at least one water soluble polymer is disclosed. Methods of making and delivering the formulation are further disclosed. The formulation of particles is deposited on a surface of internal body tissue and the deposited formulation absorbs moisture from the tissue and forms a film over the surface. The film acts as an adhesion barrier by reducing or preventing adhesion of the surface to other body tissue.
