Claim:
1. A flexible intravascular stent for use in a body lumen, comprising: a plurality of cylindrical rings aligned along a common longitudinal axis and interconnected to form the stent, each cylindrical ring having a first delivery diameter and a second implanted diameter; each cylindrical ring having a plurality of first peaks, each of the first peaks having a first height; each cylindrical ring having a plurality of second peaks, each second peak having a second height, the second height being shorter than the first height; each cylindrical ring having a plurality of valleys; and a plurality of undulating links attaching each cylindrical ring to an adjacent cylindrical ring, the undulating links having a curved portion extending transverse to the stent longitudinal axis toward the second peak, the second height of the second peak being sized so that as the stent is compressed to the first delivery diameter, the curved portion of the undulating link is longitudinally aligned with the second peak, wherein each undulating link has a first end attached to a valley of a cylindrical ring and a second end attached to a valley of an adjacent cylindrical ring, the two adjacent valleys which are attached to each undulating link being in phase with each other when the cylindrical rings are in the first delivery diameter, the undulating links attaching a first set of cylindrical rings being circumferentially offset 60° from the undulating links attaching an adjacent second set of cylindrical rings; and the undulating links attaching every other set of cylindrical rings being longitudinally aligned along a longitudinal axis of the stent.
