Compositions for enhancing wound healing are disclosed herein. Also disclosed are methods of making the compositions and methods of using the compositions for the prevention of biofilm formation and for the inhibition of pathogen growth and proliferation.

Hemostatic powders are synergistically used in conjunction with self-assembling peptide hydrogels to promote hemostasis at a target site. Related methods, kits, and devices for hemostasis are disclosed.

The present invention relates to the field of pharmaceutics and medicine, in particular, to a method for producing a suspended form of ground decellularized extracellular matrix with size-controlled structural components, the suspended form not 5 requiring pre-hydration, and to a product produced by this method, for stimulation of reparative regeneration of tissues.

The invention provides liquid formulations comprising dissolved oxygen (e.g. 10 mg/L up to 100 mg/L dissolved oxygen), and a substance which is capable of forming a gel upon contact with a body surface or body tissues, wherein said gel is capable of releasing a therapeutically effective amount of dissolved oxygen. The substance capable of forming a gel may be thermogelling and may, for example, comprise a blend of poloxamers. The liquid formulations can be applied to body tissues whereupon they form a gel suitable for the treatment of a compromised tissue, for example a wound (acute or chronic), a burn, a skin disorder (e.g. psoriasis, acne, rosacea, or other dermatological condition such as atopic dermatitis), skin sores, or tissue necrosis. The liquid formulations are also suitable for use in the prevention or treatment of a bacterial biofilm on a body surface, e.g. on the skin. The invention further provides delivery devices (e.g. wound dressings or bandages) having incorporated therein such a liquid formulation or a gel formed therefrom.

A wound dressing composition having a first layer of a lyophilized hydrogel layer having hydrolyzed collagen and hydrolyzed hyaluronic acid ingredients, wherein the first layer has a water content of 10 percent or less and is configured to lay onto a wound. The first layer can be cut or molded to various shapes such as a rectangle, a square, a polygon, an oval or a circle. The first layer is hermetically sealed in a cover or barrier and placed in final packaging. Alternatively, one or more additional layers are stacked onto the first layer, each additional one or more layers having a water content greater than that of the first layer.

Disclosed is a wound treatment that includes collagen and a gelatin-reducing agent. Also disclosed is a wound dressing including a substrate, collagen, and a gelatin-reducing agent. The collagen and gelatin-reducing agent may be present in any suitable a weight ratio relative to one another, such as a weight ratio of about 0.25:1 to about 4:1 with respect to one another. Also disclosed is a method for promoting wound healing including administering collagen and a gelatin-reducing agent to a wound in need of treatment.

The invention relates to a hemostatic composition in powder form comprising collagen of the fibrillar type comprising a content of fibrous collagen and/or fibrillar collagen of at least 70% by weight relative to the total weight of the collagen, and at least one monosaccharide, and optionally, at least one compound selected from coagulation factors and glycosaminoglycans. The invention further relates to a method for preparing such composition, and to a unit comprising such composition and a spraying device.

An improvement to the effectiveness or take of skin grafts or tissue replacements used to treat wounds is provided. A therapeutic composition comprising recombinant human platelet-derived growth factor BB homodimer (rhPDGF-BB) and a porous biocompatible carrier is first applied to the wound surface, followed by applying a skin substitute or tissue replacements composition.

The present disclosure relates to a microgel composition comprising collagen and hyaluronic acid and a method of preparing the same. The microgel according to an embodiment is composed of natural biocompatible substances and is non-toxic and has high mechanical stability or long persistence, and thus can be effectively used in a microgel composition, a three-dimensional scaffold composition, and a tissue-engineering scaffold.

The present invention is directed to a hemostatic semi-solid paste material comprising a bioabsorbable carrier hemostatic material; and a supplemental hemostatic agent; wherein the paste material has an elongated form extending along a lengthwise axis with an aspect ratio of at least 3; wherein the paste is self-supporting and syringe extrudable; and wherein the supplemental hemostatic agent has a non-homogenous distribution profile across a cross-section taken across the lengthwise axis. In another aspect, the present invention relates to devices for forming and expressing the hemostatic material.
