  • Publication number: 20250032679
    Abstract: The disclosure relates to a method of making a bioactive coating on a fibrous article for use in a medical implant and implants comprising non-biodegradable fibers, a coating polymer layer formed from a non-biodegradable coating polymer on at least a portion of the fibers, and a bioactive coating disposed on at least a portion of the polymer coating layer. In an embodiment, a method of forming a medical implant results in bioactive ceramic particles being partly embedded in the coating polymer layer.

  • Patent number: 12128158
    Abstract: The disclosure relates to a method of making a bioceramic coating on a fibrous article for use in a medical implant, comprising steps of providing an article comprising fibers made from a biocompatible, non-biodegradable polymer; coating at least the fibers that will be in contact with bone upon use as an implant with a solution of a coating polymer to result in coated fibers having a coating polymer layer; treating the coated fibers with a dispersion of bioactive ceramic particles 0.01-10 ?m in a treating solvent comprising a solvent for the coating polymer in at least one step; and substantially removing the treating solvent; to result in the particles being partly embedded in the coating polymer layer of the coated fibers.

  • Publication number: 20210299332
    Abstract: The disclosure relates to high-strength polyolefin composite fibers, which fibers have a fiber body comprising a composition consisting of polyolefin; 1-30 mass % of bioceramic particles having particle size D50 of 0.01-10 ?m; at most 0.05 mass % of residual spin solvent; optionally 0-3 mass % of other additives; and wherein the sum of a)-d) is 100 mass %; and which fibers have bioceramic particles exposed at their surface, and show bioactivity. The composite fibers based on a composition of polyolefin with bioceramic particles mixed therein show particles being exposed at the fiber surface by techniques like AFM and XPS, and although apparently only a relatively small amount of bioceramic particles is exposed at the fiber surface, this appears sufficient for effective interaction with their environment and stimulating a positive biological response as demonstrated by in vitro cell studies.

    Abstract: The disclosure relates to a method of making a bioceramic coating on a fibrous article for use in a medical implant, comprising steps of providing an article comprising fibers made from a biocompatible, non-biodegradable polymer; coating at least the fibers that will be in contact with bone upon use as an implant with a solution of a coating polymer to result in coated fibers having a coating polymer layer; treating the coated fibers with a dispersion of bioactive ceramic particles 0.01-10??? in a treating solvent comprising a solvent for the coating polymer in at least one step; and substantially removing the treating solvent; to result in the particles being partly embedded in the coating polymer layer of the coated fibers. The disclosed methods enable a relatively simple way of providing a complex shaped article like a fibrous article with a bioceramic coating, to result in a modified surface that shows bioactivity, applying biocompatible compounds and mild conditions.

  • Publication number: 20030159878
    Abstract: The present invention relates to an earplug with a through duct, in which a membrane element is adapted and comprises a membrane holder and a membrane held thereby which is adapted to lock the membrane element. The invention also relates to a method of making such an earplug and a method of affecting the course of the attenuation curve of an earplug.
