Aim of this study is to provide a computational
approach for evaluating the effect of Stents on
biomechanical outcome of deployment of stent in
different condition. Nonlinear FEA software has been
used successfully on balloon expandable stents.
Projects often require modelling systems that consist of
multiple components with nonlinear materials, complex
3D geometries. The ABACUS, handles the full range of
nonlinear material properties for the stent, the catheter
balloon, and the artery wall. The objective of research carried out was to simulate the mechanical behaviour of the stent using finite element analysis. Implantation and in vivo loading are considered. Finite element analysis
provides a quick and cost-effective method for
evaluating stent performance, yielding accurate
information about the expanded geometry and the
stress and strain deformation fields with in the stent for various loading conditions. With appropriate applied internal pressure, the balloon inside the stent is deployed which linearlyexpands the diameter of a Modular Stent until it reaches 1.7 times of its original diameter. The results will assist in the development of novel stent designs and stent deployment to minimize vascular injury during stenting and reduce restenosis.
The results obtained for the selected stent material are compared. The Cobalt-chromium undergone plastic deformation at 0.44 MPa and SS316L at 0.3 MPa pressure load
