| 英文摘要 | Biodegradable zinc alloy stents are a prospective solution for complications caused by the incompatibility between artery and permanent stents. However, insufficient scaffolding has limited the clinical application of biodegradable zinc alloy stents. Therefore, in this study, a new stent concept was designed to improve the scaffolding. The mechanical performances of the new and a traditional design stent were investigated and compared using finite element analysis (FEA). The new and traditional design stent were expanded to the intended radial displacement of 0.24 mm under the expansion pressure of 0.58 MPa and 0.45 MPa, respectively. Then, a pressure load of 0.35 MPa was exerted on the outer surfaces of the two stents to compress them. The results showed that the radial recoiling ratio were 45.3% and 83.3% for the new and the traditional stent, respectively. The simulations demonstrate that the biodegradable zinc alloy stent offers enhanced support because of the new structural design. This study implies that biodegradable zinc alloy stent can be a new competitive intervention device for the future clinical cardiovascular application. |
