Much like the production process of integrated circuits, Medinol’s pattern formation is a parallel process. This means that each panel we process contains a large number of structures that will eventually become stents. All these stents are manufactured simultaneously and uniformly and are therefore identical. This allows for process control that yields higher quality products.
Each panel is subject to an Automated Visual Inspection (AVI) that covers both sides of each and every strut of each and every stent throughout the entire panel. Thus, our quality control process is not based on sampling individual struts or stents, but is rather a rigorous and comprehensive process covering 100% of each stent’s surface.
Naturally, the two-dimensional structure of the panel allows us to apply quality control process to both sides. We are thus able to examine both the outer and inner surface of the stent with accuracy and confidence that far transcends any inspection of cylindrically cut stents
After the flat lattice is folded and fused to create a perfect cylinder the stent undergoes a unique automated electropolishing process that combines chemical and electric surface polishing technologies.
At this phase the stent is subjected to a three-dimensional quality control process, followed by crimping the stent on to the delivery system.
