Abstract
Stainless steel and nickel-titanium alloy stents for cardiac, biliary, and prostatic clinical applications may be susceptible to loss of mechanical integrity/failure due to their small size and unique geometry. Because their corrosion behavior is a critical aspect of their biocompatibility, it is necessary to test such devices for corrosion behavior using a final deployed form and finish condition. Welding wire leads or holding with metallic clips can result in surface variability or damage to the stents. A novel fixture to hold stents for corrosion testing was designed and evaluated in this study. This fixture design minimally influenced the properties of stents, and also facilitated easy removal post-testing for other types of characterization.
