Strut and Bridge Thickness

Strut and bridge thicknesses of the expanded finished stent are measured by direct measurement using a calibrated optical system. Strut and bridge thickness are measured at the stent mid-length and near each end, at two circumferential locations at each axial location. If strut and bridge thicknesses are systematically different by design, they will be measured and reported separately. Direct measurement may require test samples destruction by cutting, or flattening, or both.

ViVitro Labs Advantages

Many companies look to academia to handle their testing needs due to the reduced cost. With ViVitro Laboratory Services you gain the following advantages:

ISO 17025 Accredited
For studies used for regulatory approval this is a must. Victoria and Marseille labs accredited by A2LA.

Test Method Validation
The FDA and Notified Bodies around the world are requiring evidence of Test Method Validation. ViVitro Labs has invested significant resources to validate the most common test methods that are not ISO 17025 accredited. We continue to work closely with device manufacturers and share the burden with our clients to validate other specific test methods that are less in demand.
