Abstract:
1. A method of delivering a stent, comprising: a) providing a stent, including struts with widths, lengths and thicknesses and having a longitudinal axis, a circumference, and at least one barb, the at least one barb including an anchor portion and a shape set twisted neck, the shape set twisted neck being biased and configured to twist along its length, rotating the barb radially outward relative to the longitudinal axis, the at least one barb being part and extending from an intersection of struts, the at least one barb cut from a tube with a predetermined width and twisted about 90 degrees such that its width becomes its thickness, thereby increasing its strength, said stent and barb together defining three axes, an X-axis extending tangential to a circumference of said stent, a Y-axis extending radially outward from the circumference of said stent, and a Z-axis extending through said neck portion of said barb; b) inserting the stent into a delivery tube such that the barb is located substantially aligned with the circumference of the stent along the x-axis; and c) deploying the stent from the delivery tube and twisting the neck portion of the barb along its length relative to the intersection of the struts about the z-axis, rotating the anchor portion of the barb radially outward relative to the longitudinal axis.
