    摘要： Swellable, coated sutures have a swellable polymeric coating and a fibrous component, wherein the coating is formed of an absorbable or non-absorbable polymer, while the fibrous component is formed of a synthetic absorbable or non-absorbable monofilament yarn, synthetic absorbable or non-absorbable braided multifilament yarn, braided silk multifilament yarn or combinations thereof. In certain instances, the coating is used as a carrier for the controlled delivery of different types of bioactive agents, including those having antimicrobial, anti-inflammatory, anesthetic, tissue growth-promoting, and antineoplastic activities.

    摘要： Self-setting, absorbable bioactive polycyanoacrylate-based composites include at least one inorganic phosphate salt or a combination of at least one inorganic phosphate salt and calcium silicate in a cyanoacrylate matrix. The composites can be reinforced with single- or multicomponent absorbable, warp-knitted mesh, thus producing a broad range of absorbable, bioactive biomaterials suitable for use not only as preferred absorbable alternatives to the commercial non-absorbable polymethyl methacrylate bone cements, but also for repairing or replacing cranial and maxillofacial bone defects and other complex defects through guided bone regeneration.

    摘要： The present invention is directed to crystalline copolymers of l-lactide and a minor portion of a cyclic monomer, preferably ε-caprolactone or trimethylene carbonate or both. The present copolymers have a melting temperature of at least 150° C. and a crystallinity of at least 20%. Preferred are high molecular weight copolymers having an inherent viscosity of at least 1.1 dl/g. A variety of surgical constructs may be formed from the present copolymers. Disclosed are coated surgical constructs including sutures made of multifilament yarns of the present copolymers and coated with nitrogenous copolyesters which will bioabsorb in less than three years and will maintain at least 50% of their initial strength three weeks post-operatively.
