Abstract
Coronary artery disease (CAD), especially atherosclerosis is the major contributor of untimely and abrupt death of the maximum population of the world. Balloon angioplasty has become a popular choice of cardiac intervention owing to its minimal invasive quality for the treatment of stenosis. Of the various available commercial coronary stents in the market we have taken six commercial stents for our experimental study namely: PS stent, CYPHER stent (Cordis, J & J), S670 stent, Driver stent (Medtronic, USA), Taxus Express stent, Element stent (Boston Scientific, USA). Geometry modeling, meshing and computational simulation is done to mimic real life biological conditions (with assumptions). Of the total 192 simulation results, Element stent design has come up to be the better stent design among others and cobalt alloys specially cobalt alloy MP35N (ASTM F562) has shown the best performance by developing least von mises stress, in terms of material perspective.
