Computational Analysis on Commercially Available Stent Designs
Cardiovascular disease has become a major healthcare problem. To tackle this along with bypass surgery, the use of the cardiovascular stent is considered promising and effective. In this study, we aim to find the effectiveness of stent deployments and their influence on haemodynamics post their deployment in human arteries. For the study we have reconstructed single units of two commercially available stent designs of Cordis (JnJ, USA) using COMSOL Multiphysics®: PS Stent and Bx Velocity Stent. Five different commercially used stent materials (SS-316L, PT-Cr alloy, Co-Cr alloy, Nitinol and Tantalum) were considered. Three different stent strut geometries (rectangular, square and circular) were analyzed to study the heamodynamics post stent deployment and eventually find out the risk of restenosis.
