MAGNESIUM DEGRADATION RATE CONTROL USING ANTICORROSION EFFECT

摘要

PROBLEM TO BE SOLVED: To provide a biodegradable metal stent that has the durability over a long period of time (performance equivalent to a conventional metal stent) by coating it with a polymer entirely or partially.SOLUTION: A polymer or a polymer and vascular intimal hyperplasia inhibitor is applied to a core structure which is a base material of a biodegradable metal stent 1 entirely or partially so as to manufacture the stent having the durability over a long period of time (performance equivalent to a conventional metal stent).SELECTED DRAWING: Figure 2
