| Abstract Scope |
Absorbable magnesium wires have the potential to replace many medical devices, including staples, stents, and sternal wires, that currently are permanent additions to the body. Due to magnesium’s relatively rapid degradation rate, thin devices may not provide adequate mechanical support during the entire healing phase without surface modifications or coatings to delay the onset of corrosion. This study aimed to assess the feasibility and effectiveness of absorbable coatings which could be suitable for many different medical devices. Mg alloy LZ21 wire was drawn to 0.3 mm and annealed to impart high ductility. A portion of the wire was then anodized in an experimental electrolyte. Anodized wire was then coated with an absorbable polymer jacket of polycaprolactone (PCL). Bare, anodized, and PCL-coated wire was then subjected to both in-vitro and in-vivo degradation testing to assess coating impact. |
