    摘要: Hydroswellable, non-absorbable, biostable, segmented, aliphatic polyether-urethane-ureas or polyether-siloxane-urethane-ureas form a single component, intra-articular device for restoring joints with artificial cartilage, as a cartilage substitute for degenerated cartilage and/or for enhancing the remaining cartilage of an arthritic joint. The intra-articular devices can be bicomponent in nature comprising a biostable, articulating, non-absorbable component and an absorbable component in the form of a solid or microporous liner interfacing with the tissue of defective or diseased joint to support in situ tissue engineering. One or more bioactive agent with specific pharmacological function can be incorporated in the single or bicomponent intra-articular devices to supplement their structural functions.

    摘要: A process for making a multicomponent microbicidal contraceptive intravaginal ringed-mesh device that includes forming a polymeric, fibrous mesh and adjoining a reinforcing yarn about the periphery of the fibrous mesh. The process further involves forming a polymeric ring matrix, that includes at least one contraceptive agent on the reinforced fibrous mesh, thereby encasing the reinforcing yarn and the mesh periphery, and applying at least one bioactive agent to the ringed-mesh.

    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.
