Sierra VDI

Discover stent defect detection with confidence

The fastest measurement and inspection of coronary and endovascular stents

Sierra VDI has all of the stent measurement capabilities of the Sierra Dimensional system. Also, it can detect functional and cosmetic defects over the entire outer diameter of coronary and endovascular stents—not just selected locations.
