Stents are meshed tubes used to treat narrowed or weakened arteries. It is observed that the geometrical change created by a deployed stent may influence regional characteristics and blood flow. Restenosis can occur after the stent deployment due to neointimal proliferation. In this paper a new stent design based on a regular stent was proposed to modify the wall shear stress (WSS) of existing stent design. The fluid flow inside the stent region was then compensated to approach a regular level without disturbance of a stent. Simulation results indicated the possibility to reduce the restenosis of current stent designs.
