Medical device for implantation into luminal structures incorporating corrugated structural elements

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. 本发明涉及可扩张的模架或支架，其包括环周元件，该环周元件具有波纹状图案，该模架或支架可以包括多个线形或非线形的节段。该波纹状图案使应力沿环周元件更均匀地分布，改善支架的径向强度，减少部署之后的急性回缩，并且降低蠕变。支架可以由生物可吸收材料制成。
