    Abstract: 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.

    Abstract: A multi-cellular cellulose particle having a multiplicity of cells spaced from one another by cell membranes is described, which cells have a maximum inscribed sphere diameter of larger than 2 .mu.m. The cells have a continuous hole structure in which the cells communicate with one another through openings in the membranes separating two adjacent cells. The multi-cellular cellulose particle is prepared by forming drops of a solution of cellulose or a cellulose derivative, cooling the drops at a temperature lower than the solidification temperature of the solution to freeze the drops, and removing the solvent by extraction or nullifying the dissolving power of the solvent.
