In recent years, there is increasing interest to create biodegradable metallic cardiovascular stents instead of using their permanent form. The most interesting materials for this purpose are iron and its alloys. However, in order to use it in clinical application, their degradation rate and biological performance need to be optimized. One promising solution is coating the metal with conducting polymer films. In this work, short overview of the use of the biodegradable iron and iron modified with polypyrrole as materials for cardiovascular stents is presented.

Zastosowanie biodegradowalnych, metalicznych stentów naczyniowych staje się alternatywą dla obecnie używanych ich stałych form. Długotrwała obecność metalowego stentu w tętnicy może prowadzić do powikłań, takich jak zakrzepica czy restenoza w stencie. Odrębnym problemem może być pęknięcie stentu. Dlatego też, prowadzone są badania nad ich biodegradowalnymi formami. W tym celu stosowane są aktywne metale takie, jak na przykład żelazo, których biodegradowalność oparta jest na procesie korozji. Jednak, użycie tych materiałów do zastosowań klinicznych wymaga optymalizacji ich szybkości degradacji. Obiecującym rozwiązaniem jest powlekanie powierzchni takich metali warstwami z polimerów przewodzących. W pracy przedstawiono krótki przegląd wykorzystania biodegradowalnego żelaza oraz żelaza modyfikowanego powłokami z polipirolu, jako materiałów dla stentów sercowo-naczyniowych.
