There are some problems in the vascular prostheses, which influence the health of the patients. 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-PTFE 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.

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-PTFE and woven prostheses’ ranged from 0.73% to 0.31% / 100 mmHg and from 0.81% to 0.22% / 100 mmHg. radial compliance of pig’s carotid, ranged from 7.21% to 10.04% / 100 mmHg, there was a big gap between them.
