Controllable degradation filter

The invention provides a controllable degradation filter, at least part of the controllable degradation filter is made of a controllable degradation material, and the controllable degradation material is a material which can be degraded under set conditions and cannot be degraded under non-set conditions. The controllable degradable material is used for preparing the filter, so that when the filter starts to degrade can be manually controlled according to diagnosis of doctors and conditions of patients, and uncontrollable risks caused by spontaneous degradation of the filter can be reduced. 本发明提供一种可控降解滤器，所述可控降解滤器的至少部分采用可控降解材料制成，所述可控降解材料为在设定条件下发生降解，而在非设定条件下不会降解的材料。本发明通过使用该可控降解材料来制备滤器，使得滤器何时开始降解，能够根据医生的诊断以及患者的情况来人为控制，从而能够降低滤器自发降解所带来的不可控风险。
