摘要： The closing plug and the closing plug device are used for closing a body defect percutaneously. During the insertion into the defect, the closing plug can be deformed to a smaller size to facilitate the insertion operation and recovered to its original larger shape after it is fitted to the defect, to thereby close the defect. The closing plug device facilitates the insertion of the closing plug into the defect. The closing plug has a flange or an enlarged portion at least at one end thereof and is made of a shape memory polymer having a shape recovery temperature in the range of 20.degree. C. to 70.degree. C. The closing plug device comprises a closing plug, a catheter and a guide wire or a pushing wire to aid in insertion of the closing plug to a defect.
摘要翻译：关闭塞子和闭塞装置用于经皮闭合身体缺陷。在插入缺陷期间，封闭塞可以变形为更小的尺寸以便于插入操作，并且在闭合塞被装配到缺陷之后恢复到其原始较大的形状，从而闭合缺陷。闭合塞装置便于将闭塞塞插入到缺陷中。封闭塞至少在其一端具有凸缘或扩大部分，并且由形状恢复温度在20℃至70℃范围内的形状记忆聚合物制成。封闭塞装置包括封闭塞，导管和引导线或推动线，以帮助将闭塞塞插入缺陷。
