Patent number: 11285238Abstract: The present invention relates to an adherent interface dressing intended for application directly to a wound. Said adherent interface dressing includes a non-adherent cohesive gel formed from a hydrophobic elastomeric matrix consisting of a styrene-(ethylene/butylene)-styrene or styrene-(ethylene/propylene)-styrene triblock elastomer optionally associated with a styrene-(ethylene/butylene) or styrene-(ethylene/propylene) diblock copolymer; said elastomer plasticized by means of a mineral oil, and containing dispersed therein a small quantity of hydrophilic particles of a hydrocolloid; and a flexible open-mesh fabric, said fabric including threads coated with the non-adherent cohesive gel such as to leave the meshes substantially unsealed, The fabric is a heat-set knit with weft yarns, said yarns being continuous multifilament yarns with non-elastic filaments, whereof the extensibility in the transverse direction measured in accordance with standard EN 13726-4 is between 0.01 and 0.5 N/cm.Type: GrantFiled: December 12, 2012Date of Patent: March 29, 2022Assignees: LABORATOIRES URGO, SOCIETE DE DEVELOPPEMENT ET DE RECHERCHE INDUSTRIELLEInventors: Serge Lecomte, Jean-Marc Pernot

Patent number: 9803173Abstract: The subject matter of the present invention is a device for guiding cell migration comprising a substrate having a textured surface intended to be brought into contact with cells, said textured surface having an anisotropic three-dimensional structure consisting of a network of projections inclined relative to the normal to the plane formed by said textured structure, in the direction imparted by said anisotropic structure. The invention also concerns, according to another aspect, a method for guiding cell migration including the bringing into contact of cells with a substrate having a textured surface and an anisotropic three-dimensional structure, said structure consisting of projections inclined as previously described. The device or method according to the invention can in particular be applied in the fields of dermatology, implantology and tissue engineering.Type: GrantFiled: September 17, 2012Date of Patent: October 31, 2017Assignees: INSTITUT CURIE, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE—CNRS, SOCIETE DE DEVELOPPEMENT ET DE RECHERCHE INDUSTRIELLEInventors: Mael Le Berre, Matthieu Piel, Yong Chen, Yanjun Liu

Patent number: 9555053Abstract: The present invention relates to a compound selected among the synthetic polysulphated oligosaccharides having 1 to 4 ose units and the salts and complexes thereof to be used for the treatment of wounds resulting in pathological scars selected among hypertrophic, retractile or atrophic scars. Said use is preferred in particular in patients that have a predisposition to developing hypertrophic, retractile or atrophic scars. According to a second aspect, the invention also relates to said compound for the use thereof in order to inhibit the differentiation of fibroblasts into myofibroblasts during the cicatrisation of wounds resulting in pathological scars selected among hypertrophic, retractile or atrophic scars.Type: GrantFiled: July 12, 2012Date of Patent: January 31, 2017Assignees: LABORATOIRES URGO, SOCIETE DE DEVELOPPEMENT ET DE RECHERCHE INDUSTRIELLEInventors: Marielle Bouschbacher, Christelle Laurensou
