    摘要: Devices formed of or including biocompatible polyhydroxyalkanoates are provided with controlled degradation rates, preferably less than one year under physiological conditions. Preferred devices include sutures, suture fasteners, meniscus repair devices, rivets, tacks, staples, screws (including interference screws), bone plates and bone plating systems, surgical mesh, repair patches, slings, cardiovascular patches, orthopedic pins (including bone filling augmentation material), adhesion barriers, stents, guided tissue repair/regeneration devices, articular cartilage repair devices, nerve guides, tendon repair devices, atrial septal defect repair devices, pericardial patches, bulking and filling agents, vein valves, bone marrow scaffolds, meniscus regeneration devices, ligament and tendon grafts, ocular cell implants, spinal fusion cages, skin substitutes, dural substitutes, bone graft substitutes, bone dowels, wound dressings, and hemostats. The polyhydroxyalkanoates can contain additives, be formed of mixtures of monomers or include pendant groups or modifications in their backbones, or can be chemically modified, all to alter the degradation rates. The polyhydroxyalkanoate compositions also provide favorable mechanical properties, biocompatibility, and degradation times within desirable time frames under physiological conditions.

    摘要: The present application provides biocompatible medical implant comprising poly(4-hydroxybutyrate-co-hydroxyalkanoate) copolymer. The implant may, for example, be a device selected from guided tissue regeneration devices, tissue engineering devices, tissue engineering scaffolds, foams, coatings, meshes, microparticles, resorbable wound closure materials such as suturing and stapling materials, controlled release devices, drug delivery devices, cell encapsulation devices, targeted delivery devices, devices with biocompatible coatings, orthopedic devices, prosthetics, bone cements (including adhesives and/or structural fillers), diagnostic devices, rods, bone screws, pins, surgical sutures, stents, patches (such as hernial patches and pericardial patches), devices with vascular applications, and tubes suitable for the passage of bodily fluids. The application also provides a biocompatible polyhydroxyalkanoate that has a controlled degradation rate of less than one year under physiological conditions for use in medicine, optionally wherein the biocompatible polyhydroxyalkanoate is processed to form a medical device. The biocompatible polyhydroxyalkanoate may, for example, be produced by a process consisting of fermentation, enzymatic synthesis, chemical synthesis, melt processing, reactive blending, and recombinant techniques. The biocompatible polyhydroxyalkanoate may, for example, be produced by fermentation (a) using a co-feed, and/or (b) by a fermentation process that uses transgenic bacteria.
