Abstract: An expandable stent for implanting in a body lumen, such as a coronary artery, peripheral artery, or other body lumen. In one aspect, the stent includes a butterfly pattern to which connecting links are attached. In another aspect, the stent embodies a non-directional structure. One embodiment is a stent in which one or both ends are more flexible than the center portion. Also, the stent may have a non-uniform drug coating. Another embodiment relates to a stent having ends that are more radiopaque than the center portion.
