Abstract: Cardiovascular disease such as atherosclerosis is one of the most common diseases in modern days which may cause pain and heart attack. Stenting is non surgical method to treat the atherosclerosis. Due to its efficiency and simplicity, the use of coronary stents in interventional procedures has rapidly increased and different stents have been introduced in the market. In order to have better output of the stent implantation, it is needed to analyze the mechanical behavior of this device before manufacturing and utilizing. The aim of this work is to investigate the biomechanical behavior of stent such as non linear bending analysis at different loading conditions by using different biomaterials. One of the most effective methods to investigate the biomechanical behavior of the stent is finite element method. A commercially available finite element package ABAQUS6.10 has been used for the analysis.
