Abstract
Expandable scaffolds or stents include circumferential elements having a corrugated pattern, which can include a plurality of linear or nonlinear segments. The corrugated pattern distributes stress more uniformly along the circumferential elements, improves radial strength of the scaffolds, reduces acute recoil after deployment, and reduces creep. The scaffolds can be made from a bioabsorbable material.
