Abstract
Aim. The introduction of the full paper reviews the development of DES and then points out that the research in this paper is, in our opinion, promising for effectively resolving the restenosis problem from the short-term viewpoint. Sections 1 and 2 explain how we perform our research and present our research results. The core of section 1 consists of: (1) we construct the MAC-J09-3.0 DES model using UG software; (2) we analyze the mechanical properties of the DES with the finite element analysis software ABAQUS and optimize its topology with the optimization software OptiStruct. Section 2 optimizes the three DES brackets; Fig. 7 presents the three optimized brackets. Through mechanical analysis and comparison of threl optimized brackets, we find that the chamfer design and optimization of material distribution reinforcement can not only increase drug loading capabilities but also maintain the support stent performance.
