Real-Time Image Processing Assisted Finite Element Analysis Of Vascular Implants
Self-expanding nitinol stents are used to treat peripheral artery disease. The stented arteries are subjected to a combination of mechanical forces, such as compression, torsion, bending, and contraction. Stent fracture rates observed in clinical trials vary from 0% to 90% and depend on many factors, including stent design. The objective of this study is to accurately predict location and distribution of local stresses and strains caused by large arterial deformations. Real-time image analysis of stent deformation will be coupled with the high-performance computing finite element models. Mechanical simulation assisted implantation procedures will also be studied.
