Abstract: A surgical interface for a wound, obtained from a composition including a hydrophobic matrix comprising A parts of a triblock elastomer, B parts of a plasticiser, C parts of polyeolefin, and optionally a hydrocolloid dispersed in a proportion containing 0 to 30% of the total weight of the hydrophobic matrix, with the following relations: A=100 300<B<500 10<C<50 9%<C/(A+C)<33.5% 1.5%<C/(A+B+C)<9% 83%>B/(A+B)>75% in which the interface composition is arranged in a thin layer on a protective support, distributed with through-holes produced in the interface arranged on the protective support, in which the interface is removed from its protective support in order to be used, and has sufficient cohesion for application to a wound.

Abstract: A sterile nonstick compress having an open-mesh flexible fabric, the fabric including yarns which are coated with a cohesive and nonstick gel so as to leave the meshes essentially unobstructed, the gel being formed from a highly plasticized hydrophobic elastomeic matrix having a dispersion of hydrophilic particles of a hydrocolloid.

Abstract: A dressing with thinned edges comprising a support and an adhesive system of reducing thickness in the direction of the periphery and a process of making the dressing. The process includes the formation of an adhesive system consisting of at least two adhesive layers which are:(i) superimposed to form a set of reducing surface areas from the base, joined to the support, to the top, and(ii) arranged in such a way that two adjacent adhesive layers are joined together and have different surface areas, the edges of one of the two adjacent adhesive layers being offset relative to the edges of the other adhesive layer, the adhesive layer forming the base of the adhesive system, which is joined to the support, having a surface area which is (a) identical to that of the support and (b) greater than the surface area of every other layer of the adhesive system.

Abstract: The present invention relates to a dressing comprising a mixture of block copolymer with a saturated central sequence and plasticizer. The saturated central sequence has three sequences wherein the structure at each block is a polystyrene terminal block and the central sequence is a saturated polyolefin block.

Abstract: The present invention relates to a novel self-adhesive matrix for the percutaneous administration of an active ingredient. This matrix comprises a combination of the following:(a) 40 to 60 parts by weight of an ethylene/vinyl acetate copolymer material,(b) 40 to 60 parts by weight of a higher aliphatic monoalcohol compound,(c) 1 to 20 parts by weight of a cellulose derivative material,(d) 0.1 to 8 parts by weight of a polyhydric alcohol compound, and(e) 0.01 to 10 parts by weight of an active ingredient which can be administered percutaneously,the weight ratio a+c/b+d being between 0.7 and 1.3.

Abstract: The present invention relates to a novel self-adhesive matrix for the percutaneous administration of a pharmaceutical active ingredient. This matrix comprises a combination of the following:(a) 30 to 50 parts by weight of an ethylene/vinyl acetate copolymer material,(b) 20 to 45 parts by weight of a higher aliphatic monoalcohol compound,(c) 5 to 20 parts by weight of a cellulose derivative material,(d) 1 to 20 parts by weight of an ester compound of a polyhydric alcohol with a fatty aliphatic acid, and(e) 0.1 to 20 parts by weight of an active ingredient which can be administered percutaneously.
