Abstract
Cardiovascular stents are commonly applied in angioplasty to mitigate
coronary heart disease. A stent is a small spongy tube that’s i used to treat
narrow or weak arteries. They are expanded in the cardiac artery to remove the
plaque in order to allow for a smooth blood flow. The high variability of stent
failure incidence suggests that it is due to several correlated aspects, such
as loading conditions, material properties, component design, surgical
procedure, and patient functional anatomy. This can be solved by using suitable
biomaterial and models. Using the finite element method (FEM) this study aimed
to investigate different stent models and materials such structural steel,
titanium alloy as well as other metals or alloys to find suitable biomaterials.
A total of four (4) cardiovascular stents model materials of various densities,
poisson ratios and Young’s Moduli of elasticity were subjected to the testing
and investigated using the finite element method. Stainless steel and A-36
Steel seem to be the most suitable in the materials tested followed by titanium
and aluminum alloys. PMMA seem to be the list favourable in this investigation.
