Resoloy®
The Resorbable Magnesium Alloy for Scaffolds
With Resoloy®, MeKo offers a bioresorbable magnesium alloy with exceptional properties, serving as an attractive alternative to bioresorbable polymer scaffolds.
Properties of Resoloy®
Compared to PLLA, Resoloy® offers about three times higher strength, thinner struts, higher radial force, and is suitable for direct stent placement via balloon catheter. Coatings can adjust the degradation time from a few months (pure Resoloy®) to the desired lifespan. In addition to proven biocompatibility, Resoloy® has no shelf life and no temperature issues.

Functionality of Magnesium Alloy Resoloy®
Extensive in-vitro and in-vivo tests have been conducted for a scientific study on the degradation of vascular scaffolds (bioresorbable stents) made from the magnesium alloy Resoloy®. The results confirm that the degradation time of Resoloy® can be adjusted thanks to a double coating with fluoride and polymers. A significantly slower degradation is achieved in-vitro compared to Magmaris®. Another advantage is that Resoloy® degrades without residues. Animal experiments confirm the in-vitro results from the test laboratory and show that Resoloy® is highly biocompatible. The results of the published study demonstrate the high level of safety and efficacy of the alloy.
