FEM ANALYSIS OF CORONARY STENT DEPLOYMENT
Апстракт
As stent technology moves forward, there’s a growing need for fast and accurate stent
deployment visualizations. To that end, the Finite Element Method was used for quasi-static
analysis of a balloon expandable stent. A model was created, which includes a stent, balloon,
artery and a plaque. In order to achieve faster computation, various approximations have been
included, especially considering the balloon, artery and plaque. Some non-linear problems are
assessed, like the contact between different parts of the model. Arterial tissue and plaque are
modeled as isotropic hyperelastic materials. The balloon was specially designed and discretized to avoid the computational difficulties during inflation. Thanks to the complexity of this model,
useful results can be obtained in a reasonable time frame. The software used for FEM analysis
was ABAQUS.
