1. A stent comprising:
- a plurality of elongate struts each having a first end and a second end;
an aperture formed in at least one of the plurality of struts; and
a barb having a base and a distal anchor;
where the barb base is attached to the at least one of the plurality of elongate struts and the barb extends distally from the base through the aperture;
where the at least one of the plurality of elongate struts has a longitudinal axis and the barb extends from the at least one of the plurality of elongate struts at an oblique angle to the longitudinal axisandwhere the barb frictionally engages the stent within the aperture.
