Mathematical Modeling of Vascular Stents

Abstract: We present a mathematical model for a study of the mechanical properties of endovascular stents in their expanded state. The model is based on the theory of slender curved rods. Stent struts are modeled as linearly elastic curved rods that satisfy the kinematic and dynamic contact conditions at the "vertices" where the struts meet. This defines a stent as a mesh of curved rods. A weak formulation for the stent problem is defined and a finite element method for a numerical computation of its solution was develo… Show more

“…The ubiquity of this interaction type has led to a rapidly growing research interest in this model. Its mathematical solvability [5,9,15,17,22,21,26,32,33,34,37,38,49,55,52], numerical approximations [23,29,39,54,53,44,46], and stability [14,27,28,31] have been intensively studied.Mathematically, this interaction is described by a partial differential equation (PDE) system that couples the parabolic (fluid) and hyperbolic (elasticity) phases, where the key issue is that the traces of the elastic component at the energy level are not defined via the standard trace theory. The loss of regularity induced by the hyperbolic component left the basic question of existence open until recently.…”

“…The effect of the number of struts and the ratio between the coated area was researched by Delfour et al, and they attempted to optimize the effect of the dose (Delfour et al, 2005). A mathematical model for the study of the mechanical properties of endovascular stents in their expanded state has also been proposed (Tambaca et al, 2010). Three-dimensional models of stent expansion have been presented by, among others, (Zunino et al, 2009) and (Horner et al, 2010).…”
