Finite Element Analysis of Coronary Sent with the Presence of Plaque and Vessel by Balloon Expansion

Abstract:

Stent implantation is a non-surgical method to treat the coronary artery disease that can support vessel walls and reduce the risk of heart attack. In this paper, undertaking the 316L stainless steel as a medical stent material, a certain coronary stent is utilized to study its mechanical characteristics by the finite element analysis as it is deployed and implanted in a vessel containing a plaque, and try to reach to a model close to a real condition of stent implantation. The result shows that the width size of stent rods is greater than its thickness size in the capability of resisting deformation of configuration, and then displacement changes of the coronary stent on the axial direction should be keeping a close eye in their expansion process.
