Abstract

An intravascular stent especially suited for implanting in curved arterial portion. The stent retains longitudinal flexibility after expansion. The ste nt is formed of intertwined meander patterns forming triangular cells. The cell s are adapted to provide radial support, and also provide longitudinal flexibility after expansion. The cells also provide increase coverage of a vessel wall. Loops in the stent are disposed and adapted to cooperate, so th at after expansion of said stent within a curved lumen, the stent is curved and cells on the outside of the curve open in length, but narrow in width, where as cells on the inside of the curve shorten in length, but thicken in width to maintain a density of the stent element area which is much more constant tha n otherwise between the inside and outside of the curve. The stent also minimizes flaring out by eliminating free loops of the radially supporting circumferential bands of loops.
