A stent comprising a stent body and a plurality of cells is disclosed. Each cell includes two structural members extending in an undulating pattern. Each structural member includes a plurality of cell segments defining a plurality of peaks and valleys therebetween. A first segment and a second segment defining a first peak, the second segment and a third segment defining a first valley, the third segment and a fourth segment defining a second peak, the fourth segment and a fifth segment defining a second valley, the fifth segment and a sixth segment defining a third peak. The first peak, the second peak and the first valley include a first radius of curvature. The third peak and the second valley include a second radius of curvature. The first radius of curvature is larger than the second radius of curvature. |
