    • Abstract
  • As an improvement of the conventional 1-way bypass graft for stenosed arteries, a new geometric configuration with symmetric 2-way bypass grafts is presented. The physiological blood flow in the improved model is simulated with finite element method. The temporal and spatial distributions of the hemodynamics during a cardiac cycle, such as flow patterns, wall shear stress and pressure etc., in the vicinity of anastomosis are analyzed. The results show that the hemodynamics in the 2-way bypass grafts are better than those in the 1-way bypass graft. The 2-way bypass grafts can considerably improve the flow conditions and decrease the probability of restenosis.
