Disclosed is a dry composition comprising one or more polyols, which upon addition of an aqueous medium forms a substantially homogenous paste suitable for use in haemostasis procedures. The paste reconstitutes spontaneously upon addition of the liquid; hence no mechanical mixing is required for said paste to form. The composition may further comprise an extrusion enhancer, such as albumin. Also disclosed are methods of preparing said dry composition, a paste obtained from said dry composition and uses of said dry composition or paste for medical and surgical purposes.

The present invention describes methods and compositions of hydrogel microspheres for inducing macrophage conversion by sequentially converting a first population of wound macrophages in a wound to M2A macrophages by exposing the first population of wound macrophages to IL-4 and converting a second population of wound macrophages to M2C macrophages by exposing the second population of wound macrophages to IL-10. One aspect describes a method of inducing macrophage conversion in a wound. Another aspect describes compositions and methods of preparing a hydrogel microsphere for wound healing. Yet another aspect describes methods for treating a chronic wound with hydrogel microspheres.

A surgical sealant comprising a first agent containing a hydrophobically-modified gelatin derived from a cold-water fish, and a second agent containing a water-soluble molecule for crosslinking, wherein the water-soluble molecule for crosslinking is at least one kind selected from the group consisting of poly acids and acid anhydrides having two or more active ester groups, and aldehyde compounds having two or more aldehyde groups, the hydrophobically-modified gelatin derived from a cold-water fish is a gelatin in which at least a part of amino groups of side chains of a gelatin derived from a cold-water fish has been substituted by hydrophobic groups, and the hydrophobic groups are linear chain aliphatic groups each having 8 to 18 carbon atoms, with a substitution rate (number of moles of hydrophobic groups/(total number of moles of hydrophobic groups and reactive amino groups in gelatin)100) of 3 to 20 mol %.

The present invention relates to a dry composition, which upon addition of an aqueous medium forms a substantially homogenous paste suitable for use in haemostasis procedures. The paste forms spontaneously upon addition of the liquid, hence no mechanical mixing is required for said paste to form. The invention further relates to methods of preparing said dry composition, a paste made from said dry composition and use of said paste for medical and surgical purposes.

Provided herein are hemostatic compositions useful for treating wounds in a patient in need thereof. An exemplary hemostatic comprises gelatin or a derivative thereof and silicate nanoparticles. Methods of use, kits comprising the compositions, and a process of making the compositions are also provided.

The present invention relates generally to agents and devices for promoting hemostasis and, more particularly, to an extract of a plant-based Traditional Chinese Medicinal product and devices incorporating such agents for the delivery thereof to bleeding wounds.

According to an illustrative embodiment a method to promote healing of a wound is provided comprising contacting the wound with a biologically active composition comprising a lipoic acid derivative and gelatin. In another embodiment a wound dressing is provided comprising a scaffold coated with a biologically active composition comprising a lipoic acid derivative. In a further embodiment, a system is provided for treating a tissue site of a patient, the system comprising a reduced-pressure source to supply reduced pressure, a manifold to distribute reduced pressure to a tissue site and a scaffold coated with a biologically active composition comprising a lipoic acid derivative. Methods for producing such a system and scaffold are also disclosed.

A dynamic antimicrobial hydrogel based on natural receptor-ligand recognition, and a preparation method and use thereof are provided. A ligand vancomycin and a receptor AA-based material each are first modified with a modification material, and then a photoinitiator is added to prepare a hydrogel material under irradiation of ultraviolet (UV) light. In the hydrogel, a three-dimensional (3D) network structure is formed through crosslinking. After undergoing a fracture under an external pressure, the hydrogel can rapidly heal itself through crosslinking due to a ligand-receptor interaction and a multi-hydrogen-bond interaction, which bio-mimicks a natural ligand-receptor interaction to realize the dynamics of the hydrogel material. The high antiomicrobial activity of vancomycin imparts the functionality of the hydrogel material; and the physiologically-derived monomer improves the biocompatibility and reduces the biological toxicity.
