Abstract--Objective This study aims to compare and analyze the scaffold performance of a new stent and a common stent which is chosen as a control group. Method Using finite element analysis, the new stent and the common stent are simulated to implant into vessels with a diameter stenosis of 30%, their scaffold performance and their effects on reshaping the stenotic vessels are investigated. Results Radial recoiling ratio and dog-boning ratio of the new stent are decreased by 26.6 % and 34.7% respectively compared with the common stent. Besides, a flatter and larger lumen can be observed in the plaque treated with the new stent. Conclusions The new stent has a stronger scaffold performance and a more brilliant effect on reshaping stenotic vessel, compared with the common stent. It is suggested that the new stent with strong scaffold performance is highly promised to be an alternative choice in interventional surgeries. Improving mechanical performance of biodegradable stents via novel structure design is of highly significance to promote clinical application of biodegradable stents.
