  • Publication number: 20230311472
    Abstract: A medical appliance or prosthesis may comprise one or more layers of rotational spun nanofibers, including rotational spun polymers. The rotational spun material may comprise layers including layers of polytetrafluoroethylene (PTFE). Rotational spun nanofiber mats of certain porosities may permit tissue ingrowth into or attachment to the prosthesis. Additionally, one or more cuffs may be configured to allow tissue ingrowth to anchor the prosthesis.

  • Publication number: 20220305061
    Abstract: A method for making an acellular human amnion-derived composition configured for therapeutic use is disclosed and generally includes the steps: obtaining amniotic membrane tissue; testing the amniotic membrane tissue for pathogens; washing the amniotic membrane tissue; manually removing blood-containing chorion tissue from the amniotic membrane tissue decellularizing the amniotic membrane tissue with xeno-free enzymes; collecting amniotic cells from the decellularized amniotic membrane tissue; seeding the amniotic cells for culture into xeno-free media formulated for mesenchymal stem cells; growing the amniotic cells to a specified confluency; collecting conditioned media; and freezing the collected conditioned media; wherein the method further includes irradiating the conditioned media.

  • Publication number: 20220133807
    Abstract: Methods of treating alopecia, connective tissue disease, or chronic skin wounds in a subject by administration of a therapeutically effective amount of a novel acellular human amnion-derived composition are disclosed. The novel acellular human amnion-derived composition is generally characterized as containing: one or more tissue-remodeling biomolecules, one or more proliferation biomolecules, one or more angiogenic biomolecules, one or more migration biomolecules, one or more anti-inflammatory biomolecules, and one or more anti-microbial biomolecules. Moreover, the acellular human amnion-derived composition is sterilized under conditions that preserve biological functionality and efficacy. Other features and characteristics of the treatment methods and compositions are described.
