Abstract

The introduction of a rigid stent into an elastic artery results in the formation of wave reflection sites at the entry and exit of the stent. It has been demonstrated that the stiffness of the stent, as well as its length and position within the diseased channel, all have an effect on a stent's clinical performance. The net haemodynamic effects of these reflections are highly dependent on the stent's length and position inside the diseased channel. Closed circulatory systems display a delicate equilibrium between the effects of vascular elasticity and viscous fluids in order to facilitate the smoothing of the pulse and prevent "resonance during the cardiac cycle. The placement of stents in the artery tree disrupts this equilibrium by making the arterial tree more rigid and by adding a periodic structure that is capable of" complex interactions with the fluid. Wave reflection in blood vessels has been thoroughly described in the literature; however, it has always been connected to a significant difference in geometry, such as vessel branching. This is because wave reflection is only observed when there is a significant difference between the two geometries. The characteristics of the wave's dispersion are investigated in this paper, and the stent construction has an effect on those characteristics. The model incorporates this structure because overlapping stents are utilized in a number of the vascular stinting procedures.
