In a first aspect, the current invention concerns a method for fabricating an intrauterine device (IUD), said method comprising the step of providing a coaxial rod comprising an outer polymeric layer and a polymeric core, and further comprising the step of cutting from said rod at least one rod segment having a predetermined length, whereby, simultaneously to cutting said rod segment from said rod, the rod end portions thereby formed are compressed into dome-shaped end portions, in such a way that, at said dome-shaped end portions, said polymeric core is at least partly enclosed by said outer polymeric layer. In a second aspect, the current invention concerns a device for cutting a rod segment from a rod.
