Effects of fatigue on the chemical and mechanical degradation of model stent sub-units

- New method presented for aligning degradation with fatigue of absorbable stents.
- Fatigue loading during degradation increased the stiffness of stent sub-units.
- Fatigue loading during degradation decreased force at break of stent sub-units.
- Fatigue during degradation significantly increased the molecular weight loss.
- Results suggest interactions between fatigue and degradation of absorbable stents.
