摘要：
A stent, composed of linear components, comes into close contact with a tissue in vivo through being deformed when set indwelling in vivo . The stent 1 has linear components which are deformed to exhibit a force for maintaining dilation when the stent is set indwelling in vivo, and the linear components deformed when the stent is set indwelling in vivo are composed of non-biodegradable metallic linear components 21, 22, 23, 24 and a plurality of biodegradable material-made linear components 3 which are bonded to the non-biodegradable metallic linear components 21, 22, 23, 24. Furthermore, when set indwelling in vivo , the stent 1 exhibits the force for maintaining the dilation owing to both the non-biodegradable metallic linear components 21, 22, 23, 24 and the biodegradable material-made linear components 3. After a predetermined period of time, biodegradation of the biodegradable material-made linear components 3 proceeds, which results in a lowering in the force for maintaining the dilation.
摘要（中）：
由线性组分组成的支架在体内留置时通过变形而与体内组织紧密接触。 支架1具有线性部件，该线性部件在支架留置于体内时表现出用于保持扩张的力，并且当支架设置在体内留置时发生变形的线性部件由不可生物降解的金属线性部件21,22 ，23,24以及与非生物降解性金属线性部件21,22,23,24接合的多个生物降解性材料制线状部件3.此外，在体内留置时，支架1发挥维持力 由于不可生物降解的金属线性部件21,22,23,24和生物可降解材料制成的线性部件3两者的膨胀。在预定时间段之后，进行生物可降解材料制成的线性部件3的生物降解，结果 降低维持扩张的力量。
