Abstract:

Biodegradable metals, designed to be safely degraded and absorbed by the body after fulfil the intended functions, are of particular interest in the 21st century. The marriage of advanced biodegradable metals with clinical needs have yield unprecedented possibility. Magnesium, iron, and zinc-based materials constitute the main components of temporary, implantable metallic medical devices. A burgeoning number of studies on biodegradable metals have driven the clinical translation of biodegradable metallic devices in the fields of cardiology and orthopaedics over the last decade. Their ability to degrade as well as their beneficial biological functions elicited during degradation endow this type of material with the potential to shift the paradigm in the treatment of musculoskeletal and cardiovascular diseases. This review provides an insight into the degradation mechanism of these metallic devices in specific application sites and introduces state-of-the-art translational research in the field of biodegradable metals, as well as highlighting some challenges for materials design strategies in the context of mechanical and biological compatibility.

Key words: biodegradable metals, cardiovascular applications, clinical translation, degradation mechanism, orthopaedic applications
