severely restricted to use as implant and at the same time the use of other materials such as stainless steel and then titanium as biomaterial were increasing with time [26]. A summary of Mg based materials used in cardiovascular applications is shown in Table 1.

6. Techniques to improve the corrosion resistance of magnesium
In its metallic form, magnesium has several material advantages such as high strength, excellent thermal con- ductivity, dimensional stability and damping characteristics. In addition, magnesium also has a low density and good electromagnetic shielding properties and it is easy to mechanize and recycle [56]. Unfortunately, the use of c.p Mg does not provide the best mechanical properties and corrosion resistance required to be used in implants; however alternative solutions such as the use of alloys or coatings have been used in order to improve the material performance Fig.3 [42,56].
Fig.3 Corrosion resistance of c.p Mg can be improved by the addition of other elements (Magnesium based Alloys or by coating the material through different techniques
