  • Patent number: 11806440
    Abstract: The instant disclosure is directed to methods of improving bone-soft tissue healing using biocompatible electrospun polymer fibers. In one embodiment, a method may include locating a portion of a subject's bone, affixing a tendon or ligament to the bone using a hardware fixture, and placing a patch comprising at least one electrospun polymer fiber in physical communication with both the bone and the tendon or ligament. In some embodiments, the bone may be a humerus, and the tendon or ligament may be a supraspinatus tendon. In certain embodiments, the patch may comprise substantially parallel electrospun polymer fibers, and may be placed such that the fibers are also substantially parallel with the long axis of the tendon or ligament.

  • Publication number: 20230285445
    Abstract: A method of treating a chronic wound may comprise applying to the wound a first scaffold comprising an electrospun polymer fiber. The electrospun fiber may comprise a polymer selected from the group consisting of polyglycolic acid, poly(lactide-co-caprolactone), polylactic acid, polycaprolactone, copolymers thereof, and combinations thereof. The first scaffold may have a thickness from about 50 ?m to about 1 mm, a length from about 1 cm to about 20 cm, and a width from about 1 cm to about 15 cm. The method may further comprise keeping the first scaffold on the chronic wound for a time period of about 3 days to about 21 days. After the time period passes, the chronic wound may have a decreased planimetric area.

  • Patent number: 10953097
    Abstract: A fiber may comprise an electrospun polymer and a contrast agent. A method of making an electrospun fiber may comprise configuring a receiving surface to receive a polymer fiber, applying a charge to one or more of the receiving surface, a polymer injection system, and a polymer solution ejected from the polymer injection system, and depositing a polymer solution ejected from the polymer injection system onto the receiving surface. The polymer solution may comprise a polymer and a contrast agent.

  • Publication number: 20190388359
    Abstract: The instant disclosure is directed to methods of promoting the healing of concave wounds. A method for promoting the healing of a concave wound may comprise placing a scaffold over the concave wound, the scaffold comprising an electrospun polymer fiber. The scaffold may be pressed into the concave wound, such that the scaffold simultaneously contacts at least a bottom portion of the concave wound and at least a side portion of the concave wound. The method may be suture free. The scaffold employed in such a method may have an asterisk shape comprising a center and at least two spokes, and pressing the scaffold into the concave wound may comprise pressing the center of the scaffold into the bottom portion of the concave wound, and allowing the at least two spokes of the scaffold to fold upward to contact the side portion of the concave wound.
