ABOUT THE WEBINAR:
Finite element modeling and simulation has been widely applied in the development of medical device and surgical planning. Our group developed a framework to implant the implantable and interventional device virtually by finite element simulation. Three applications of the finite element modeling and simulation are presented in this talk. Application 1, the whole process of the deployment of one braided stent to treat a cerebral aneurysm was simulated, the deformation of the parent artery and the distributions of the stress in the parent artery wall were investigated. The results provided some information to improve the intervention of cerebral aneurysm and optimize the design of the flow diverter. Application 2, the whole process of the deployment of the stent graft to treat an aortic dissection was simulated, and the distributions of the stress in the aortic wall were investigated when the different oversize ratio of the stent graft was selected. The simulation results proved that the maximum stress located at the position where the bare metal ring touched the artery wall. The results also can be applied to improve the intervention of the aortic dissection and the design of stent graft. Application 3, the aortic valve reconstructive surgery using autologous pericardium on the finite element model following standard procedure was performed, and the hemodynamic characteristics between diseased model, normal model, and operative models were compared. The study found that matching inherent fiber orientation of the pericardium to the circumferential direction of the trimmed leaflet may be unnecessary during operation.
