The compositions of the present invention comprise at least one medium polarity oil and at least one antibacterial agent, the combination of which produces a synergistic antibacterial effect against bacterial biofilms. Methods are disclosed for the reduction of bacteria in and/or elimination of bacterial biofilms on biological and non-biological surfaces, as well as methods for the treatment of wounds, skin lesions, mucous membrane lesions, and other biological surfaces infected or contaminated with bacterial biofilms.

The invention relates to a bio-conjugate comprising a chitosan derivative coupled to antimicrobial peptides (AMPs) for use in the treatment or prevention of microbial infections such as wound healing. The invention also provides a nanoparticles formulation or a gel/hydrogel formulation or a lyophilized foam formulation comprising the bio-conjugate of the invention.

The present disclosure relates to birch bark extracts, methods of producing such extracts, stable pharmaceutical corn-positions containing such extracts and methods of using of such extracts. The birch bark extracts of the present disclosure contain triterpenes, which are known to improve wound healing.

An improved surgical device is disclosed herein. The improved surgical device includes a delivery device and a sealed container. The sealed contained is prepositioned internal to the delivery device and includes an antimicrobial solution. The improved surgical device is configured for inserting an implant into a surgical site. In some embodiments, the sealed container is configured to be manually broken to release the antimicrobial solution prior to inserting the implant into the delivery device. In other embodiments, the sealed container is configured to be automatically broken to release the antimicrobial solution prior to inserting the implant into the delivery device.

Liquid compositions are described which have enzyme that is able to convert a substrate to release hydrogen peroxide; substrate for the enzyme; and polymer. The substrate is less than 10% by weight of the composition and the composition does not comprise sufficient free water to allow the enzyme to convert the substrate, or has a water activity of 0.7 or less.

The present invention relates to a hemostatic composition including collagen, a stabilizer, and thrombin, and a container holding this hemostatic composition. The hemostatic composition and the container holding this hemostatic composition can be applied to an urgent bleeding patient by a simple method of use, and the hemostatic composition is less toxic, does not have a problem of blood infection, has a fast rate of biodegradation, has an excellent hemostatic effect, and can be usefully used as a hemostat.

Disclosed are compositions comprising a copper complex useful in the reduction of inflammation in one or more tissues. Also disclosed are methods of utilizing the copper complexes for treating/preventing inflammation in one or more tissues, treating/enhancing wound healing, preventing/reducing DNA damage caused by radiation, and reducing free radical damage.

The inventive subject matter provides compositions and methods for transiently or permanently treating or managing an injury. Contemplated compositions are polymerizable in situ over short time periods, even in the presence of blood, without undue exothermic heat. Contemplated compositions may further comprise an anesthetic, an antiseptic, an adhesion promoter, and/or a vasoconstrictor.

Disclosed embodiments relate to wound care materials and methods that comprise a self-gelling composition, configured to form a gel upon contacting fluid. The self-gelling composition is a substantially homogeneous mixture, and comprises fluid-absorbent particles loaded with iodine-based antimicrobial agent, a dehydrated hydrogel powder, and a polymer base, configured to allow dispensing the self-gelling composition from a syringe or tube and to prevent the self-gelling composition from gelling prior to contacting fluid. The gel performs one or more of the following tasks during a wear time, when applied at the wound: absorbing fluid or exudate, releasing iodine-based antimicrobial agent, achieving antimicrobial activities at the wound, remaining structurally integral and cohesive, protecting the wound from exposure to microorganisms, and facilitating healing. After a wear time of at least three days, the gel can be removed in two pieces or less and leave less than 5% residue by weight.

The present disclosure relates to a biocompatible composition comprising a solution of low molecular weight polymer and high molecular weight polymer. The present disclosure also relates to biocompatible compositions comprising poly(lactic-co-glycolic acid) (PLGA) and poly(ethylene glycol) (PEG), and additionally including a suspension of silica particles and/or a therapeutic agent. The present disclosure is also directed to biocompatible polymer fiber constructs formed from the disclosed compositions, methods of fabrication thereof, and uses of such constructs and compositions.
