This disclosure provides a hydrocolloid having a super absorbent material chemically bonded either directly or indirectly to a peroxide. The peroxide is within the hydrocolloid and the peroxide is in an amount of 0.05% to 2% by weight within the hydrocolloid.

A dressing composition for use as a skin dressing comprises an elastomeric-adhesive composition, and a zeolite comprising releasably adsorbed nitric oxide. The zeolite may comprise a transition metal cation such as Co, Fe, Mn, Ni, Cu, Zn, Ag or a mixture thereof as an extra-framework metal cation, preferably Zn. The elastomeric adhesive composition may be a hydro-colloid-adhesive composition comprising, hydrocolloid and elastomer. The dressing composition releases nitric oxide, which may have beneficial effects, when used on wounds or moist skin, with a substantially constant release rate over a long period of time. A dressing including a layer of the dressing composition has a backing layer and may have a release liner removably attached to the skin-contacting surface of the dressing layer.

The present invention concerns a three-dimensional bipolymeric matrix deploying biological and biomechanical activity, able to neutralize the various physiopathological parameters involved in the development and worsening of skin lesions and/or sores, combining: a first polymeric network comprising first colloids (Col-1) bonded non-covalently to an unsulfated crosslinked polysaccharide; and a second polymeric network comprising second colloids (Col-2) bonded covalently or non-covalently to a sulfated polysaccharide.

An aerosol spray device includes a container having first and second fluid reservoirs disposed therein that are divided from one another. The first fluid reservoir holds a first mixture including a first aerosol propellant and a first part of a silicone based topical skin adhesive that is dissolved in the first aerosol propellant. The second fluid reservoir holds a second mixture including a second aerosol propellant and a second part of the silicone based topical skin adhesive that is dissolved in the second aerosol propellant. An aerosol spray dispensing system is connected with the container, which is configured to combine the first and second mixtures to form the silicone based topical skin adhesive and dispense the silicone based topical skin adhesive from the container as an aerosol spray.

Hemostatic compositions including a combination of more than one hemostatic agent, and devices coated or impregnated therewith, have been developed. Nanotechnology yields hemostatic agents with large surface areas thereof, thereby increasing the hemostatic properties of the device to which they are applied. By combining more than one hemostatic agent and utilizing one or more different nanotechnology approaches to enhance the surface areas thereof, the capability of the dressing to stop bleeding is improved via more than one mechanism, and thus provides better hemostasis.

The present invention relates to a new multifunctional debridement and/or antifouling composition comprising H.sub.2O.sub.2 at a final concentration of between 0.1-5% v/v, and a composite hydrogel formulation comprising pluronic acid at a concentration of 10-40% w/v, wherein the composition is in liquid form at room temperature. The composition disclosed herein is antimicrobial and/or anti-inflammatory and is particular useful in periimplantitis treatment and implant health maintenance, in periodontitis and periodontal health and in wound care and chronic ulcer care.

The invention provides a constituent that is used with a novel method for preventing and/or treating skin wounds and ensures stable delivery of low-concentration hydrogen sulfide to a wound site. The skin wound-preventing and/or treating constituent includes a sustained hydrogen sulfide releasing agent that is preferably a layered double hydroxide having HS— and/or Sk2- between layers where k is a positive integer.

Film forming gel compositions, useful in creating conformable and flexible gel bandages, can be formulate from a film-forming polymer, a tackifier, and a volatile solvent. The film forming gels can also include antiseptics, cationic polymer coagulants, fillers, and other additives. The gel compositions form relatively thick films when dried on tissue, and can exhibit enhanced breathability to promote wound healing.

In at least one embodiment there is a wound application comprising at least one film applied over a wound comprising at least 1% green tea, and at least 0.01% sugar, wherein said film comprises a polymeric film comprising united chains and monomeric glucose points. In at least one other embodiment there is a wound application comprising a solution comprising at least trace amounts of colloidal silver, at least trace amounts of sodium chloride, at least trace amounts of dextrose; and water, wherein the colloidal silver, the sodium chloride and the dextrose are dissolved in water. In at least one other embodiment there is an application for treating a wound comprising both a solution comprising at least trace amounts of colloidal silver and a film comprising at least trace amounts of green tea applied over the solution on top of a wound.

The present invention relates to methods for adhering tissue surfaces and materials and biomedical uses thereof. In particular the present invention relates to a method for adhering a first tissue surface to a second tissue surface in a subject in need thereof, comprising the steps of adsorbing a layer of nanoparticles on at least one of the tissue surfaces, and approximating the surfaces for a time sufficient for allowing the surfaces to adhere to each other. The present invention also relates to a method for adhering a material to a biological tissue in a subject in need thereof, comprising the steps of adsorbing a layer of nanoparticles on the surface of the material and/or the biological tissue and approximating the material and the biological tissue for a time sufficient for allowing the material and the biological tissue to adhere to each other.
