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.

Abstract: An electrospun onlay for rotator cuff repairs and related procedures. The onlay includes an aperture and a conduit extending towards the aperture, wherein a longitudinal axis of the conduit is aligned with the aperture. The aperture and the conduit are configured to receive one or more surgical sutures therethrough. The scaffold is electrospun from one or more biocompatible polymers. In use, the onlay serves as a tissue growth scaffold to facilitate tendon-bone reattachment.

Abstract: A cultured meat product may comprise a scaffold comprising an electrospun polymer fiber, and a population of cells. The cultured meat product may have a thickness from about 100 ?m to about 500 mm. A method of producing such a cultured meat product may comprise preparing the scaffold, placing the scaffold into a bioreactor, adding the population of cells to the bioreactor, culturing the population of cells in the bioreactor containing the scaffold for a period of time, thereby forming the cultured meat product, and removing the cultured meat product from the bioreactor. The cultured meat product may be configured to mimic the taste, texture, size, shape, and/or topography of a traditional slaughtered meat.

Abstract: Systems and methods of forming electrospun structures including pharmaceuticals are disclosed. An electrospun structure can include one or more polymers electrospun from a polymer solution comprising a pharmaceutical such that the pharmaceutical is dispersed throughout the one or more electrospun polymers. The pharmaceutical can include a cannabinoid, a phytocannabinoid, a terpene produced by a cannabis plant, or a combination thereof. The one or more electrospun polymer are configured to degrade over a predetermined time period to deliver the pharmaceutical over the predetermined time period.

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.

Abstract: A scaffold may comprise a first polymeric electrospun fiber comprising a first material having a first degradation rate, and a second polymeric electrospun fiber comprising a second material having a second degradation rate different from the first degradation rate. The first degradation rate may substantially correspond to a cell infiltration rate, and the second degradation rate may be slower than the first degradation rate. Such a scaffold may be manufactured by electrospinning a first polymer fiber having a first degradation rate by ejecting a first polymer solution from a first polymer injection system onto a mandrel, and electrospinning a second polymer fiber having a second degradation rate different from the first degradation rate by ejecting a second polymer solution from a second polymer injection system onto a mandrel. Wound healing may be improved by applying such a scaffold to a portion of a wound.

Abstract: A system for manufacturing an artificial construct suitable for transplantation into a biological organism that includes a two or three three-dimensional preform that is based on the actual two or three-dimensional structure of a native mammalian tissue; and an electrospinning apparatus, wherein the electrospinning apparatus is operative to deposit at least one layer of polymer fibers on the preform to form a polymer scaffold, and wherein the orientation of the fibers in the scaffold relative to one another is substantially parallel.

Abstract: A synthetic construct suitable for implantation into a biological organism that includes at least one polymer scaffold; wherein the at least one polymer scaffold includes at least one layer of polymer fibers that have been deposited by electrospinning; wherein the orientation of the fibers in the at least one polymer scaffold relative to one another is generally parallel, random, or both; and wherein the at least one polymer scaffold has been adapted to function as at least one of a substantially two-dimensional implantable structure and a substantially three-dimensional implantable tubular structure.
