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.

Abstract: The invention relates to a method for forming a barbed suture (10) comprising: a) producing a knit by knitting together i) a set of chain stitch yarns (1) producing chain stitches and ii) a set of monofilament weft yarns completing weft stitches with at least one of said chain stitches, thereby producing at least one weft stitched chain stitch (6), b) cutting the knit along the warp direction on both sides of said weft stitched chain stitch, so as to isolate said weft stitched chain stitch from the rest of the produced knit, the chain stitch yarn of said at least one weft stitched chain stitch forming the elongate body (9) of the barbed suture and the monofilament cuts (7) extending from said weft stitches of said one weft stitched chain stitch forming the barbs (8) of said barbed suture.
