Implanted cardiovascular devices, such as pacemakers, are exposed to the potential risk of thrombosis, which often shortens their lifespan. Previous laboratory studies have demonstrated the effectiveness of slippery surfaces in preventing thrombosis formation on medical devices. However, there is a lack of quantitative understanding of how the slippage effect influences hemodynamics near implanted devices under physiological conditions. In this study, we implemented a slip boundary condition into our solver and validated it by comparing it to an analytical solution using a concentric pipe geometry. We conducted blood flow simulations using a patient-specific anatomical model of the jugular vein with a pacemaker, both with and without slippery surfaces. As a result, we demonstrated that as the slip length increases, the residence time in the region between the blood vessel wall and the pacemaker’s lead decreased by 64.6%. Our results provide computational evidence of the effectiveness of slippery surfaces for thrombosis prevention.
