Interface Engineering of Fully Metallic Stents Enabling Controllable HO Generation for Antirestenosis.

Langmuir 2019 03 27;35(10):3634-3642. Epub 2019 Feb 27.

Center for Biomaterials , Korea Institute of Science and Technology (KIST) , Seoul 02792 , Republic of Korea.

Despite significant advances in the design of metallic materials for bare metal stents (BMSs), restenosis induced by the accumulation of smooth muscle cells (SMCs) has been a major constraint on improving the clinical efficacy of stent implantation. Here, a new strategy for avoiding this issue by utilizing hydrogen peroxide (HO) generated by the galvanic coupling of nitinol (NiTi) stents and biodegradable magnesium-zinc (Mg-Zn) alloys is reported. The amount of HO released is carefully optimized via the biodegradability engineering of the alloys and by controlling the immersion time to selectively inhibit the proliferation and function of SMCs without harming vascular endothelial cells.
