  • Patent number: 9101681
    Abstract: The present application discloses an alternative method for the formation of non-woven with fibers in the 1 to 200 ?m range. Using an aqueous solution of gelatin (optionally with <30% of low molecular weight alcohol) the fibers are ejected utilizing pressurized air emitted from nozzle and the non-woven formed directly from the emitted thin fibers. The gelatin non-woven can be cross-linked by heat-treatment or chemical cross-linking, and the non-woven is biocompatible as measured by fibroblast growth in vitro and wound healing on pigs in vivo.

  • Patent number: 8877223
    Abstract: The present application discloses biodegradable polymers, to porous and other materials comprising such polymers, and to various medical uses of such materials, including use as a scaffold for supporting cell adhesion or the in-growth for regeneration of tissue. The polymer is of the formula A-O—(CHR1CHR2O)n—B wherein A is a poly(lactide-co-glycolide) residue, the molar ratio of (i) lactide units [—CH(CH3)—COO—] and (ii) glycolide units [—CH2—COO—] in the poly(lactide-co-glycolide) residue being in the range of 80:20 to 10:90, B is either a poly(lactide-co-glycolide) residue or hydrogen, C1-6-alkyl or hydroxy protecting groups, one of R1 and R2 is hydrogen or methyl, and the other is hydrogen, n is 10-1000, the molar ratio of (iii) polyalkylene glycol units [—(CHR1CHR2O)—] to the combined amount of (i) lactide units and (ii) glycolide units in the poly(lactide-co-glycolide) residue(s) is at the most 14:86, and the molecular weight of the copolymer is at least 20,000 g/mol.

  • Publication number: 20120165957
    Abstract: The present invention relates to new reinforced biodegradable scaffolds for soft tissue regeneration, as well as methods for support and for augmentation and regeneration of living tissue, wherein a reinforced biodegradable scaffold is used for the treatment of indications, where increased strength and stability is required besides the need for regeneration of living tissue within a patient. The present invention further relates to the use of scaffolds together with cells or tissue explants for soft tissue regeneration, such as in the treatment of a medical prolapse, such as rectal or pelvic organ prolapse, or hernia.

  • Publication number: 20110014267
    Abstract: An isolated, acellular biosynthetic cartilaginous matrix substantially devoid of synthetic biodegradable scaffold structure is provided. Through a method with the steps of a) contacting in vitro a population of chondrogenic cells with a synthetic biodegradable scaffold; b) culturing in vitro for a period of time said chondrogenic cells within said synthetic biodegradable scaffold so that the chondrogenic cells produce a biosynthetic cartilaginous matrix; c) substantially removing any antigen derived from said chondrogenic cells a matrix suitable of implantation into a living individual mammal, such as a human being is obtained.

  • Patent number: 7863264
    Abstract: A stabilised composition having antibacterial, antiviral and/or antifungal activity, said composition comprising silver ions and a ligand, characterised in that the composition comprises a complex of silver and a ligand selected from the group consisting of 5,5-disubstituted hydantoins in which the substituents do not comprise conjugated unsaturated bonds and barbituric acid and derivatives thereof stabilising silver ions against reduction to free silver in a hydrophilic environment, and that the composition has a solubility in water higher than 10 mg Ag/l is stable during sterilisation and retains the activity without giving rise to darkening or discoloration of the dressing during storage.
