SPRINGERBRIEFS IN MATERIALS BIODEGRADABLE MET...

This book in the emerging research field of biomaterials covers biodegradable metals for
biomedical applications. The book contains two main parts where each of them consists of three
chapters. The first part introduces the readers to the field of metallic biomaterials  exposes
the state of the art of biodegradable metals  and reveals its application for cardiovascular
implants. Some fundamental aspects to give basic understanding on metals for further review on
the degradable ones is covered in chapter one. The second chapter introduces the concept of
biodegradable metals  it's state of the art and discuses a shifted paradigm from inert to
bioactive  from corrosion resistant to corrodible metals. The third chapter focuses on the
challenges and opportunities of using biodegradable metals for cardiovascular applications. The
second part exposes an example of biodegradable metals from its concept to applications where a
complete study on metallic biodegradable stent is detailed from materials design  development 
testing till the implant fabrication. The forth chapter reveals new alloys development devoted
for metallic biodegradable stent based on required criteria derrived from clinical needs and
current nondegradable stents properties. Degradation of the alloys in simulated arterial
conditions and its effect to cells are exposed in chapter five. The both chapters are concluded
with a benchmarking of some more recent researches on materials development and testing for
biodegradable stents. Chapter six reveals the tranformation process of the materials into stent
prototypes where a standard process for making 316L stainless steel stents was followed. The
book is completed by a perspective on the use of biodegradable metals for biomedical
applications in the era of tissue engineering.
