Comparison of Mechanical Performance of the Various Stent Materials: A Finite Element Analysis (FEA) Approach

The objective of this research work is to study and compare the mechanical properties of different biocompatible materials used in stent implantation viz. Aluminium Alloy (AA2024), Magnesium alloy (Mg–10Al–3Zn), Stainless steel (SS316L), and Titanium alloy (Ti–6Al–4V). At present, the materials used for stentings such as Cobalt–Chromium alloy, Stainless Steel SS316L, Magnesium alloy, and Nitinol are not reasonable and cause problems to the artery. The material world is marching toward the trend of improving the strength and simultaneously reducing the weight of the material. Hence, in this work, an effort has been made to use Titanium alloy material for cardiovascular stents; this material has been preferred as an entrant material that has remarkable biocompatibility, extraordinary strength-to-weight ratio, resistance to corrosion, and also exhibits good mechanical properties and resistance to corrosion.
