AI Technical Summary
Existing biodegradable vascular scaffolds made of magnesium alloys face issues with uncontrolled degradation, galvanic corrosion, and inadequate X-ray visibility, which can lead to premature detachment and restenosis, complicating their manufacturing and deployment.
A vascular scaffold made of a biodegradable magnesium alloy with a form-fitting or force-fitting rare-earth metal radiopaque marker, such as dysprosium, is covered with an inorganic magnesium fluoride coating, minimizing galvanic corrosion and ensuring stable radiopacity.
The solution provides a scaffold with controlled degradation and enhanced X-ray visibility, reducing the risk of restenosis and ensuring the scaffold remains intact during endothelialization, facilitating easy manufacturing and safe deployment.
