Marker Card

Selecting the right marker size for a stent rarely happens in one step.

Small changes in diameter or wall thickness can already change how markers appear in X-ray imaging. What looks fine on paper does not always translate into sufficient contrast for accurate placement during stent deployment. In many cases, this leads to multiple iterations just to answer a simple question: which configuration is actually visible enough?

To make that comparison easier, we developed the MeKo marker card. It combines a Nitinol base design with tantalum, gold, or platinum markers in different diameters and strut widths. Arranged in a structured layout, the card allows direct comparison under X-ray within seconds. Its stent-like geometry mirrors how markers actually behave in a real implant.

Instead of working through several prototype loops, the card reduces development time and removes guesswork early in the process.

At MeKo, not every solution is part of the final implant. Some are built to support decisions before that stage. And with the marker card now available through our webshop at shop.meko.de, it can be easily integrated into early-stage evaluation.
