Abstract:

Coronary artery stents are the most important implantation devices for the practice of the interventional cardiology to treat coronary artery disease (CAD) since the mid-1980s. However, the problems of stent thrombosis (ST) and in-stent restenosis (ISR) still exist. In addition to the reasons of implanted materials and coatings, mechanical and structural factors are also important factors and responsible for the complications, such as inadequate stent expansion, incomplete stent apposition and stent fracture in design. This research aims to develop a concurrent topology optimization by a parametric level set method associated with numerical homogenization method, to generate novel architectures for self-expanding (SE) stents with mechanical auxetic metamaterials. The topological design is firstly implemented in MATLAB, and then the optimized architecture is further improved and optimized in the commercial software ANSYS. The final stenting structure is numerically validated to demonstrate the effectiveness of the design method.
