Abstract

An intravascular stent especially suited for implanting in curved arterial portion. The stent retains longitudinal flexibility after expansion. The stent is formed of intertwined meander patterns forming triangular cells. The cells are adapted to provide radial support, and also provide longitudinal flexibility after expansion. The cells also provide increase coverage of a vessel wall. The stent has a reduced crimped profile due to the differing lengths of adjacent structural members within the cells, resulting in loops which are not aligned around the circumference of the stent. Also, this stent may contain a second type of square cells, which are adapted predominately to minimize flaring of the stent ends and to provide additional stiffness.
