A composition for treating a wound includes graphene oxide (GO) and hyaluronic acid (HA) that are covalently linked, XAV939, and water. The composition can also include a surfactant, such as PEG. The composition can be topically administered to a subject to treat a wound of the subject. Methods of treating a wound using the composition are also provided.

One-way adjustable loop suture constructs and methods of forming and using the same
11272920 · 2022-03-15 · ·

Surgical constructs and methods of use for a one-way adjustable fixation loop are formed by tying two knots in a surgical filament, each knot defining an individual adjustable loop and the individual adjustable loops being interconnected to form the one-way adjustable fixation loop. The knots enable a non-spliceable suture to be used in the creation of the one-way adjustable fixable loop. Embodiments can include a fixation device, such as a cortical button or plate for use in a bone tunnel, and enable the knots to work independent of and suspended below the fixation device. Embodiments can increase the compatibility of the adjustable fixation loop with existing fixation devices and can isolate and protect the knots from damage during use and after implantation.

Threads of hyaluronic acid and/or derivatives thereof, methods of making thereof and uses thereof

The present invention provides threads of hyaluronic acid, and/or derivatives thereof, methods of making thereof and uses thereof, for example, in aesthetic applications (e.g., dermal fillers), surgery (sutures), drug delivery, etc.

Readily Absorbable Copolymer Compositions for High-Strength Sutures Having Enhanced Strength Retention Post-Implantation

Novel surgical sutures and novel medical devices made from novel semi-crystalline, glycolide-rich A-B-A triblock copolymers of glycolide and lactide, wherein said B-segment is a fully amorphous random copolymer of glycolide and lactide, for long term medical applications are disclosed. The novel polymer compositions are useful for long term absorbable surgical sutures, meshes and other medical devices, especially for patients with compromised healing. The novel sutures have improved properties and improved breaking strength retention, while still substantially absorbing within about a 120-day period post-implantation.

ANTIBIOTIC ELUTING POLY(ESTER UREA) FILMS, MESHES AND POUCHES FOR INFECTION CONTROL OF IMPLANTABLE MEDICAL DEVICES
20210316038 · 2021-10-14 ·

In various embodiments, the present invention is directed to a drug-loaded amino acid based poly(ester urea) pouch or pocket sized to receive implanted devices that produces localized drug delivery. In some embodiments, the present invention is directed to an antibiotic-loaded L-Valine poly(ester urea) pouch or pocket that provides localized antibiotic delivery for CIEDs or other implanted devices. In one or more embodiments, the amount and rate of antibiotic release are dependent upon the thickness and loading concentration of the film. This dependence of release on thickness and loading concentration gives a handle to fabricate PEU-A pouches or pockets with any desired release profile that can locally deliver the therapeutically relevant amount of antibiotic.

Polypeptides and medical uses thereof
11136374 · 2021-10-05 · ·

The present invention provides polypeptides comprising or consisting of an amino acid sequence derived from collagen type VI or a fragment, variant, fusion or derivative thereof, or a fusion of said fragment, variant or derivative thereof, wherein the polypeptide, fragment, variant, fusion or derivative is capable of killing or attenuating the growth of microorganisms. Related aspects of the invention provide corresponding isolated nucleic acid molecules, vectors and host cells for making the same. Additionally provided are pharmaceutical compositions comprising a polypeptide of the invention, as well as methods of use of the same in the treatment and/or prevention of microbial infections and in wound care. Also provided are a method of killing microorganisms in vitro and a medical device associated with the pharmaceutical composition.

Method for the heat-fixing of a sutured site
11207174 · 2021-12-28 · ·

A suture to be used in producing a medical instrument provided with a sutured site such as a stent graft, an artificial blood vessel or an artificial heart valve, has two components, i.e., a high melting-point component and a low-melting point component, the difference between the melting points of components being 30° C. or more and the low-melting point component is exposed on the suture surface entirely along the length direction. When a medical material formed of a fabric or a film is sutured or knotted with the suture and then the suture site is heated at such a temperature not allowing the high-melting point component but the low-melting point component alone to melt, the sutured site is fused and fixed. Thus, a knot or a seam, which sustains the fiber shape and strength and never becomes loose, can be formed.
