文摘
- •
Consideration of vessel anisotropy produced different behaviour in stent expansion.
- •
Anisotropic vessel model gave lower recoiling but higher stress in artery layers.
- •
Arterial stiffness highly affected the lumen diameter achieved by stent expansion.
- •
Residual stress significantly affected the deformation of the stented system.
- •
Collapse of the system under radial compression was facilitated by residual stress.
