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.

Abstract: The invention provides a bioabsorbable blend of (i) a polymer component comprising polylactic acid (PLA), polyglycolic acid (PGA), a copolymer of PLA and PGA, or any combination thereof and (ii) thermoplastic polyurethane (TPU) tailored to a medical application, and a process for making the same. In some embodiments, the TPU comprises units derived from a diol chain extender, a diisocyanate, and a polyol formulated to provide a set biodegradation rate in combination with at least one physical property. The blend of the invention provides useful materials for medical applications that have the individual benefits of polylactic acid and TPU while moderating each material's typical limitations.

Abstract: The composition comprises a mixture of: i) poly(L-, D-lactide) homopolymer and, optionally, poly(ε-caprolactone) homopolymer, and ii) poly(L-lactide) and poly(ε-caprolactone) diblock copolymer, where said copolymer has a molar mass of the L-lactide block of 20,000 g/mol to 200,000 g/mol and a molar mass of the ε-caprolactone block of 10,000 g/mol to 100,000 g/mol, with the molar ratio between the L-lactide block and the ε-caprolactone block of 2:1. The invention also refers to the nanostructured material obtained from this composition that is characterized by a nanostructure of two mutually self-assembled phases, one phase being formed by a polymeric matrix of poly(L-, D-lactide) units and the other phase by poly(ε-caprolactone) units self-assembled with the matrix and also its use for the manufacture of a plastic article in the form of a transparent film or thin sheet.
