Cases of death caused by cardiovascular disease are commonly coronary heart disease. The most well-known way to treat it is by installing a stent. Several studies related to the development of stents have been done. Continues in the materials used, one of which is the development of biodegradable materials so that the stent will dissolve in the body over time. In addition, when installed, the stent should be able to adjust its shape to the blood vessel and have a minimum tension so that it will not injure the vessel wall. This study investigated a bare metal stent with magnesium alloy AZ31 material using a strut mirror design (S><). The study used two stent conditions, namely crimped and expanded stent, to obtain changes in angle and maximum stress on the bending moment when simulated. The bending moment test simulates the finite element method (FEM) on Abaqus 6.14 software. The study results showed that to get the highest flexibility in crimped stent conditions, the best flexibility using von Mises stress in the safety limit is 0.011 N.mm bending moment and 50 μm thickness, with a curvature index of 0.0519 mm.
