Abstract

Stents may comprise a bioabsorbable polymer and a plurality of circumferential elements. Circumferential elements that are adjacent to one another may form an adjacent pair that is connected by one or more first connection elements and one or more second connection elements. In some embodiments, the circumferential elements may be formed from undulations having a sinusoidal pattern. The first and second connection elements and portions of the circumferential elements may form a substantially helical pattern across the longitudinal axis of the stent. In one embodiment, the first connection element may include one or more radiopaque markers. In some embodiments, the second connection elements may be curvilinear and may become substantially linear after the expansion of the stent. Curvilinear second connection elements may facilitate the expansion of the stent radially while overall length of the stent remains substantially constant.
