A process for producing a surgical implant with a marking

In a method of manufacturing a surgical implant is a flexible planar basic structure (10) having a first side surface (12) and a second side surface is provided. At least one linear marking thread (20) is laid floating, placed on one of the side surfaces of the base structure (10) and mechanically (for example by stitching) to the base structure (10) at a first location (21, 21 ', 23) and at a second location (22, 22 ', 24) which are spaced from each other, placed. Thereafter, the linear marking thread (20) is thermally in a range between the first point (21, 21 ', 23) and second locations (22, 22', 24) fixed by a fusion bonding process to the base structure (10).
