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.
