Abstract
Stents are medical devices implanted in blood vessels to physically expand them so blood can flow. Stents can be deployed in different parts of the human body such as iliac arteries, biliary ducts and cerebral arteries to name a few. Coronary heart stents are stents implanted in the coronary artery to prevent myocardial infarctions. There are currently more than a hundred different stents on the market, they differ in material, size, frequency and shape; scientifically there is still no method on how to compare their mechanical properties. This study proposes a way of doing that by simulating different stent types, using finite element analysis, imposing a crimped state stent, where the medical device is submitted to an external pressure in order to reduce its radial size so it will be able to pass thru all the blood vessels until it arrives in the correct position inside the coronary artery, and statistically comparing the simulation results. Stents were tested in three different diameters, three shapes, four lengths, five frequencies and two materials totalizing 360 simulations with comparison between Stress, Strain and Deformation.
