    摘要: The present invention provides novel hydrogel-forming, self-solvating, absorbable polyester copolymers capable of selective, segmental association into compliant hydrogels upon contacting an aqueous environment. Methods of using the novel polyester copolymers of the invention in humans are also disclosed for providing a protective barrier to prevent post-surgical adhesion, treatment of defects in conduits such as blood vessels, and controlled release of a biologically active agent for modulating cellular events such as wound healing and tissue regeneration or therapeutic treatment of diseases such as infection of the periodontium, dry socket, bone, skin, vaginal, and nail infections

    摘要: A coating and tubing fluid for sutures, especially gut sutures, is provided. The coating composition includes linseed oil, an organic solvent and a catalyst. The tubing fluid includes water, a softening agent, a C.sub.2 -C.sub.4 alcohol and a lubricant of fatty acids, fatty acid alcohols and/or triglycerides of fatty acids. Gut sutures coated with the coating composition may be stored or packaged in the tubing fluid to provide sutures with improved flexibility, pliability, run-down performance and superior resistance to fraying and breaking.

    摘要: Copolymers are prepared from 1,5-dioxepan-2-one and lactide and/or glycolide. The copolymers are useful in surgical applications such as sutures, suture lubricants, and allied surgical products. 1,5-Dioxepan-2-one is produced by a new process comprising first reacting ethylene glycol with an alkyl acrylate to form alkyl 3-(2-hydroxyethoxy)propionate, which is then cyclized by contacting with a trans-esterification catalyst.

    摘要: Synthetic filaments composed of homopolymers and copolymers of poly(alkylene oxalates) are absorbable in animal tissue with minimal adverse tissue reaction. Polymers prepared by reacting a dialkyl oxalate with an alkylene diol are melt spun and drawn to obtain oriented fibers having good tensile properties and a high level of flexibility and softness. The filaments are particularly useful in the preparation of surgical prosthesis comprising woven or knitted fabrics and meshes. Other absorbable surgical devices including films and molded items may also be prepared from the disclosed polymer.
