  • Publication number: 20230093766
    Abstract: Coated bone grafts are provided as well as methods of use thereof and methods of making. In accordance with the instant invention, methods of preparing a coated bone graft (e.g., bone allograft) are provided. In certain embodiments, the method comprises electrospraying a composition comprising a polymer and, optionally, an agent, particularly a therapeutic agent, onto the surface of the bone graft. Therapeutic agents include, without limitation: bone stimulating agents, anti-fibrotic agents, antimicrobials, anti-inflammatory agents, and pro-angiogenesis agents.

  • Publication number: 20230053327
    Abstract: A multi-laminar electrospun nanofiber scaffold for use in repairing a defect in a tissue substrate is provided. The scaffold includes a first layer formed by a first plurality of electrospun polymeric fibers, and a second layer formed by a second plurality of electrospun polymeric fibers. The second layer is combined with the first layer. A first portion of the scaffold includes a higher density of fibers than a second portion of the scaffold, and the first portion has a higher tensile strength than the second portion. The scaffold is configured to degrade via hydrolysis after at least one of a predetermined time or an environmental condition. The scaffold is configured to be applied to the tissue substrate containing the defect, and is sufficiently flexible to facilitate application of the scaffold to uneven surfaces of the tissue substrate, and to enable movement of the scaffold by the tissue substrate.

  • Publication number: 20220175510
    Abstract: A structure of aligned (e.g., radially and/or polygonally aligned) fibers, and systems and methods for producing and using the same. One or more structures provided may be created using an apparatus that includes one or more first electrodes that define an area and/or partially circumscribe an area. For example, a single first electrode may enclose the area, or a plurality of first electrode(s) may be positioned on at least a portion of the perimeter of the area. A second electrode is positioned within the area. Electrodes with rounded (e.g., convex) surfaces may be arranged in an array, and a fibrous structure created using such electrodes may include an array of wells at positions corresponding to the positions of the electrodes.
