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 μm 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.

Methods of treating chronic wounds using electrospun fibers

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.

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.

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.

Electrospun fibers having contrast agents and methods of making the same

A composition may comprise a plurality of polymeric electrospun fiber fragments, and a carrier medium comprising an effective amount of chitosan. Such a composition may further include a plurality of polymeric electrospun fiber fragment clusters. A kit may comprise a first component of a plurality of polymeric electrospun fiber fragments, and a second component of a carrier medium comprising an effective amount of chitosan. A method of treatment may comprise injecting into a portion of a body a composition which may comprise a plurality of polymeric electrospun fiber fragments, and a carrier medium comprising an effective amount of chitosan. The treatment may be directed to one or more of joint inflammation, osteoarthritis, a tissue injury, a muscle tear, a ligament tear, a tendon tear, a void, incontinence, an aneurysm, and a tumor.
