This paper aims to the radial compliance of three kinds of vascular prostheses and the pig＇s carotid based on the dynamic-simulated condition. The radial compliance of knitted structure vascular prostheses with crimps ranged from 2.52% to 0.94%/100 mmHg, which was superior to e-FFFE and woven prostheses＇, ranged from 0.73% to 0.31%/100 mmHg and from 0.81% to 0.22%/100 mmHg. But comparing with the radial compliance of pig＇s carotid, ranged from 7.21% to 10.04% /100 mmHg, there was a big gap between them. And also the trend of the radial compliance of vascular prostheses was different from the real pig＇s carotid. There is a lot of work left to improve the radial compliance, not only to change the vascular prostheses＇ compliance, but also to meet with the real vascular.展开更多
