The cardiovasualar diseases have become contemparary and continueosly growing problems. The main reason for such problems are the intra vessel depositions of plaque, cholesterol ect,. A traditional cure for such problems is implanting a stent. Stenting is one of the most impartent methods to treate atherosclerosis. Coronary stents are small metallic tubes in heart arteries to prevent the arteries from clossing up. Over 40 different types of stents are commercially available or in development and they are made up of stainless steel, Co-Cr alloy, plantinum, tantalum ect,. Several research papers have been published concerning stents and their properties and most of these focused on material Biocompatability and the reaction between stent and tissues. In this work mechanical properties also have to be taken into account.Coronary stent geometry was constructed from a CT scan and slices are seved as DICOM, 3D doctor software was used to convert CT scan images into 3D models. The model was imported into ANSYS for stress analysis. The results are drawn for two types of stents with different material properties of biocompatability materials. The results sre validated for the type 2 with Co-Cr alloy.
