An embodiment includes a wound dressing comprising: a shape memory polymer (SMP) foam, including open cells, having first and second states; and a hydrogel (HG) included within the cells; wherein (a) in a first position a composite, including the SMP foam and the HG, is configured to be located proximate a hemorrhagic tissue with the SMP foam in the first state; (b) in a second position the composite is configured to be expanded to the second state against the hemorrhagic tissue when the SMP foam is plasticized at 37° C. depressing a glass transition temperature (T.sub.g) of the SMP foam to below 25° C. Other embodiments are described herein.

The invention is directed to a tissue-adhesive polymer blend comprising a bioresorbable carrier polymer and a bioresorbable synthetic tissue-reactive polymer as well as to a tissue-adhesive device for sealing dura mater comprising said tissue-adhesive polymer blend.

A skin compatible component attachable to mammalian skin. The component is formed as a foamed silicone matrix comprising a polyorganosiloxane derived silicone polymer and moisture control particulate distributed within the polymer network being configured to absorb moisture from the skin. The foamed skin compatible component may be utilised as an ostomy wafer or flange to secure an ostomy appliance to the skin and in particular peristomal skin.

The invention relates to the use of a polyphosphate salt as procoagulant mediator agent in medical devices or pharmaceutical compositions and the respective polyphosphate-containing medical devices and pharmaceutical compositions. The invention further relates to a method for preparing an aqueous fibroin solution by use of a microwave treatment. The invention further relates to a fibroin-containing structure produced or obtainable by the preparation method of the invention. The invention further comprises subsequent process steps leading to solidified fibroin products and to the use of said products for medical treatment.

An ostomy appliance has a waste collection bag attached to an adhesive wafer. The adhesive wafer includes an adhesive layer, a backing layer deposited on a distal side of the adhesive layer, a hole formed through the adhesive layer, and a neutralizing layer deposited on the distal side of the adhesive layer. The neutralizing layer is in direct contact with the adhesive layer and is inside of the waste collection bag. The neutralizing layer has a neutralizer that is adapted to neutralize output from the stoma.

The invention is directed to a biodegradable tissue-adhesive device for sealing tissue, said device comprising a tissue-adhesive layer which comprises a blend of a tissue-reactive polymer and a biodegradable carrier polyurethane according to the formula of A-B-C-B.sub.n, wherein A denotes a polyol, B denotes a diisocyanate moiety, C denotes a diol component and n denotes the number of recurring units, and wherein the B-C-B segment is bioresorbable.

The invention relates to a biocompatible, flexible, bone-adhesive sheet that may suitably be applied in the treatment of bone defects, said bone-adhesive sheet comprising: a cohesive fibrous carrier structure comprising a three-dimensional interconnected interstitial space; distributed within the interstitial space, (i) a plurality of polymer particles comprising a water-soluble calcium-binding polymer, said water-soluble calcium-binding polymer carrying at least one calcium binding group or (ii) a plurality of reactive particles comprising an electrophilically activated water-soluble polymer and a plurality of bisphosphonate particles comprising nitrogenous bisphosphonate.

Provided is a hemostatic dressing. The hemostatic dressing includes: a porous matrix layer including a biocompatible polymer; a hemostatic layer loaded on the porous matrix layer and including a polymer in which polyhydric phenol-containing moieties are introduced; and a binding layer interposed between the porous matrix layer and the hemostatic layer to prevent the porous matrix layer from being separated from the hemostatic layer.

The present invention provides a tissue sealing plug comprising a substrate comprising foamed gelatin impregnated with polyethylene glycol that is liquid at room temperature, wherein the weight ratio of polyethylene glycol to foamed gelatin in the substrate is about 4:1 to about 6.8:1 and the substrate is substantially free of air, along with methods of using the plug for closing tissue punctures in the lung.

Compositions comprising a mixture of an antimicrobial cationic polypeptide and a second pharmaceutically-acceptable polymer are disclosed, as well as methods and uses thereof for the treatment and prevention of infections that occur when our natural barriers of defense are broken.
