A method of manufacturing a barbed stent, comprising:
- providing a stent material;
- cutting the stent material to form a stent segment with at least one integral barb extending therefrom;
- orienting the at least one integral barb in a first direction;
- and
- bending the stent segment in a second direction, transverse to the first direction, to form at least one bend connected to two struts.
