EXTENDED ABSTRACT

In this work, the stents-induced mechanical responses of a patient-specific common carotid artery (CCA) were evaluated through computational simulation. The realistic 3D geometry of the artery was constructed from the MRI data. Two types of self-expanding stent design (open-cell and closed-cell) were used to restore the blood flow inside the 60 % stenosed artery. The resulting lumen gain, dog-boning effect and arterial stress were estimated. Results suggested that the artery was straightened after stent implantation, and the open-cell design led to bigger lumen gain, better conformability, and less dog-boning effect. This work may facilitate the development of new stent designs
