Abstract: The invention relates to a method for forming a mesh having a barbed suture attached thereto, comprising the following steps: a) producing a knitted structure on a knitting machine comprising at least one needle-bed with three guide bars, on a length corresponding to N stitches ranging from 1 to N, wherein i) a first knit portion is produced along stitches ranging from 1 to x, where 1<x<N, ii) a second knit portion is produced for stitches ranging from (x+1) to N, in which the knitting pattern produces at least one weft stitched chain stitch, b) cutting the second knit portion on both sides of the weft stitched chain stitch and along an edge separating the second knit portion from the first knit portion, while maintaining the weft stitched chain stitch attached to the first knit portion. The invention also relates to the mesh obtained by this method.

Abstract: The invention relates to a method for forming a prosthetic base knit (1) made of two parallel sheets of porous knits, namely a first sheet (2) of porous knit and a second sheet of porous knit, said two parallel sheets being joined together in a discrete manner by a plurality of connecting porous knits (4) spaced apart from each other. The invention further relates to a method for manufacturing H-shaped prostheses for hernia repair from said base knit thus obtained and to the prostheses obtained therefrom.

Abstract: The invention relates to a prosthesis for supporting a breast implant comprising: a reinforcement part configured to receive a curved lower portion of a breast implant, the reinforcement part having an elongation under 50N in the vertical direction of E1, a fixation part intended to be fixed to the pectoral muscle, the fixation part having an elongation under 50N in the vertical direction of E2, and a transition part connecting together the reinforcement part and the fixation part, said transition part having an elongation under 50N in the vertical direction of E3, wherein E3 is greater than E1 and greater than E2.

Abstract: The invention relates to a knit having barbs protruding outwards from both faces obtained by knitting yarns of biocompatible material in guide-bars B2, B3 and B4 of a knitting machine, wherein the knitting patterns followed by guide-bars B2 and B3 involve at least two needles and produce an arrangement of yarns defining two faces of the knit, the knitting pattern followed by guide-bar B4 making stitches generating loops protruding outwards from each of the faces of the knit, guide-bar B4 being threaded with a hot-melt monofilament yarn, heat-setting the knit, forming barbs by cutting the loops via melting.
