Abstract

Experimental and clinical evidence indicate that degree of arterial injury after stent implantation is strongly linked with various stent designs. In this study, Computational models are developed to predict stents-induced arterial strain and stress during the stenting procedure. The intramural stresse filed in the stenotic vessel wall is obtained to understand the injuries caused by stent implantation. Circumferential tensile stresses are maximal in the wall near the plaque edge, and the stress values are much higher than the tensile strength of the wall medial. Stress gradient at the interface among the stent, plaque and artery are also high. These results indicate a possibility of the injury near the edge of contact surface. The stress gradient and the vessel injury may be reduced by alternating stent designs.
