Abstract

Self-expandable braided stents are widely used for carotid artery stenosis due to flexibility. Finite element (FE) models of braided composite stents with different proportions of NiTi and Mg-2.1Nd-0.2Zn-0.5Zr (JDBM) alloy (24NiTi (24:0), 20NiTi (20:4), 16NiTi (16:8), 12NiTi (12:12), 8NiTi (8:16), 4NiTi (4:20)) were constructed to analyze their radial compression strength and longitudinal bending flexibility. The 4NiTi stent showed the highest radial support (16.39N) and decreased bending strength by 7.72%. These results suggest that replacing more NiTi with JDBM wires enhances the stent's radial strength and reduces bending stiffness, providing new insights into stent design.
