| Abstract Scope |
Molybdenum (Mo) is emerging as a promising material for intravascular bioresorbable devices, such as stents and flow diverters. Many factors can affect the degradation of materials, including environment and material deformation. A bivariable static corrosion experiment was used to better understand the interactions that may affect Mo in vivo corrosion. Four different solutions, each containing representative combinations of proteins, organic components, and ions, were analyzed with three different Mo foil deformation states (no deformation, C-deformation, and L-deformation). Sample mass change and solution elemental concentrations will quantify the degradation rates of Mo. Macro- and micromorphology will provide pivotal surface level information about the corrosion pattern of the material. This study will provide insights into how the different components within the blood affect the degradation of Mo, as well as any alterations in corrosion induced by Mo deformation that may be caused during manufacturing or implantation of an intravascular medical device. |
