Simulation of deployment of multiple stents within deformable artery

Abstract

© 2019 IEEE. One of the most common clinical treatments of arterial stenosis is the implantation of an endovascular prosthesis called a stent. Computer modeling represents a useful tool that enables the analysis of the complex behavior of the stent during implantation within a patient specific artery. The numerical model presented in this paper can simulate the expansion of multiple stents, as well as the interaction of the stents with the arterial wall and the behavior of the arterial wall due to the forces caused by the stents. Also, GPU principles are used during implementation, to enable the execution of simulations in real time. In this paper, two stents are deployed within patient-specific artery and the results of this simulation are presented. The numerical models that are originally applied in engineering are used in the presented numerical model, in order to create a useful tool that can be used in bio-medicine. This software can be used for a more detailed prediction of the shape of the stents and artery after implantation and thus this software can improve the techniques used for treatment of the arterial stenosis and pre-operative patient-specific planning.
