Material comprising a flexible porous hydrophilic polymer foam or fibre matrix comprising two matrix faces and therebetween a structural matrix framework defining a network of cells, having a cell network surface and therein a network of pores and a powder charge comprising antimicrobial additive and/or wound dressing additive, wherein the powder charge is comprised at the matrix face or faces and/or within the cell network or within the structural matrix framework and wherein the additive is micronized, a method for the preparation thereof comprising micronizing the additive and dosing powder charge to the matrix or a reactive phase for the manufacture of said matrix, devices comprising the material and uses thereof.

Wound care materials, devices and uses

Flexible polyurethane (PU) material which comprises a flexible hydrophilic polyurethane foam porous matrix comprising two matrix faces and therebetween a structural matrix framework defining a network of cells, having a cell network surface and therein a network of pores and a powder charge comprising one or more additives loaded in said structural matrix framework wherein said material is a foamed polymer of a system comprising an isocyanate prepolymer or monomer phase and an aqueous phase, wherein said system comprises one or more slurry phases or solid concentrates of said powder charge, or an insoluble portion thereof, as said isocyanate phase or part thereof and/or as said aqueous phase or part thereof and/or in a carrier liquid phase; and/or comprising a powder charge of silver salt loaded in said structural matrix framework in a population of silver salt particles defined by particle size distribution about a mean particle size of greater than or equal to 1 micron, said material comprising silver salt in population of particles corresponding to silver salt comprised in powder charge pre-loading; methods for manufacture thereof, systems for control thereof, devices containing said material and methods for treatment therewith and uses thereof.

Polymer foam material, device and use

The present invention relates to a negative pressure wound closure system and methods for using such a system. Preferred embodiments of the invention facilitate closure of the wound by preferentially contracting to provide for movement of the tissue.

Devices and methods for treating and closing wounds with negative pressure

Bioresorbable or biodegradable polymers formed from the monomers including sulphonyl diphenol, hydroxybenzoic acid and dicarboxylic acid. The dicarboxylic acid can include aliphatic dicarboxylic acid or a mixture of aliphatic dicarboxylic acid and aromatic dicarboxylic acid. Between 25 and 85 molar percent of the polymer is formed from the hydroxybenzoic acid, between 7.5 and 37.5 molar percent of the polymer is formed from the sulphonyl diphenol, and between 7.5 and 37.5 molar percent of the polymer is formed from the dicarboxylic acid. Polymers can be used for manufacturing fibers and composite devices.

Polymer compositions and devices

The present invention relates to scaffolds which can be used as medical devices for guided tissue regeneration and repair, in particular the invention is directed to a scaffold comprising fibers having a mean fiber diameter of between from about 1.2 to 4.0 microns, wherein the fibers comprise a glycolide. The invention further relates to the use of the scaffolds for the selective capture of cell populations for a cell source material.
