“…In physiological environments, corrosion was observed for a variety of biomaterials. [5][6][7][8] A novel principle to utilize corrosion for biodegradable implants was introduced in 2001 with corrodible iron stents. 9 The ideal temporary stent for paediatric applications should corrode over a period of 3-6 months.…”

The principle of biodegradation for the production of temporary implant materials (e.g. stents) plays an important role in the treatment of congenital heart defects. In the last decade several attempts have been made with different alloy materials—mainly based on iron and magnesium. None of the currently available materials in this field have demonstrated satisfying results and have therefore not found entry into broad clinical practice. While magnesium or magnesium alloy systems corrode too fast, the corrosion rate of pure iron‐stents is too slow for cardiovascular applications. In the last years FeMn alloy systems were developed with the idea that galvanic effects, caused by different electrochemical properties of Fe and Mn, would increase the corrosion rate. In vitro tests with alloys containing up to 30% Mn showed promising results in terms of biocompatibility. This study deals with the development of new FeMn alloy systems with lower Mn concentrations (FeMn 0.5 wt %, FeMn 2.7 wt %, FeMn 6.9 wt %) to avoid Mn toxicity. Our results show, that these alloys exhibit good mechanical features as well as suitable in vitro biocompatibility and corrosion properties. In contrast, the evaluation of these alloys in a mouse model led to unexpected results—even after 9 months no significant corrosion was detectable. Preliminary SEM investigations showed that passivation layers (FeMn phosphates) might be the reason for corrosion resistance. If this can be proved in further experiments, strategies to prevent or dissolve those layers need to be developed to expedite the in vivo corrosion of FeMn alloys. © 2014 Wiley Periodicals, Inc.

“…However, there is increasing evidence of ion leakage from metallic implant materials. The accumulation of implant degradation products in the surrounding tissue has been demonstrated for orthodontic implants, orthopedic implants, and also for cardiovascular implants [1][2][3][4][5][6][7][8]. Even implants made of stainless steel slowly corrode under physiological conditions [6].Tungsten was the first cardiovascular implant material used that showed complete dissolution in humans [9].…”

“…Surgically removed stainless steel sliding hip screwplates have shown significant wear, corrosion, and damage to the surrounding tissue. [23] Similar work with implant alloys such as titanium and 316L steel [24][25][26] has supported these observations. Additionally, Toshikazu and Mitsuo [27] showed a relationship between fatigue damage and mechanical properties in Ti6Al4V alloy.…”
