完全生物可降解封堵器植入体内后逐渐降解并被自身组织代替,不需要在体内永久停留,相比传统金属不可降解心脏缺损封堵器更具优势.现综述完全生物可降解封堵器的材料选择、主要结构、优点、存在的问题及研发趋势.“,”The totally bioabsorbable occluder does not stay in the body permanently ,can be gradually degraded in vivo and replaced by “native” tissue after being implanted .This obtains more benefits compared with a no degradable metal occluder .This review examines the choice of biomaterials and designs ,advantages and shortages ,future research direction of the totally bioabsorbable occluder .
