Outline of Final Research Achievements |
In this study, a new balloon expanded stent is developed to reduce damage to a blood vessel wall due to the stent expansion. For the development, firstly, the deformation of both the blood vessel and plaque due to the stent expansion is clarified using finite element method (FEM). The results of FEM analysis show that the eccentric stent is effective to reduce the damage due to the stent expansion. First, the deformation characteristics are clarified considering the surface roughness of a symmetric stent. After that, some eccentric stents are proposed and the effect of the eccentric stents are verified by the FEM analyses. As a result, it is found that the eccentric stents are valuable to reduce the damage of both blood vessel and plaque due to the stent expansion.
