Finite element model

A finite element model represents an essential tool for the structural analysis of different cardiovascular stent geometries. Through this approach, it is possible to investigate in detail the distribution of stresses and strains arising both during the expansion and deployment phases and subsequently under physiological loads imposed by the blood vessel. Finite element analysis also enables the comparison of different stent geometrical configurations, identifying those capable of providing adequate mechanical support to the vascular wall while minimizing the risk of material fracture or restenosis. In this way, the numerical model becomes a valuable instrument for design optimization and for the development of safer and more effective devices.

Fluid Dynamic Models 

The three-dimensional model of the aortic bifurcation represents a fundamental tool for investigating the interaction between the implanted device and the surrounding hemodynamic field. It faithfully reproduces the typical dimensions and geometries of the aortic bifurcation, thereby providing the basis for a detailed fluid dynamic analysis that accounts for both the three-dimensional modeling of the device and the fluid properties, including pressure, rheological behavior, and mean blood flow.

The primary advantage of this approach lies in its ability to accurately assess the influence of the manufactured stent on the hemodynamics within the blood vessel, enabling a deeper understanding of post-implantation flow conditions and supporting the optimization of device design and performance.
