超顺应性的可回收覆膜分段支架研制

Preparation of Recyclable Membrane-coveredUltra-compliance Segmented Stent

本文提供了一种超顺应性的可回收覆膜分段支架,并介绍其结构及制备方法。本支架本体内部设有一层独立的且与分段部位存在相互活动间隙的内套膜,在自由弯折的过程中膜筒仍然可以贴合人体,并采用了独立的外套膜的结构,使得支架易于各种弯曲角度。该支架具备超柔性,可顺应人体管腔生理结构等优势,可减少管腔增生,穿孔、出血等严重并发症。

Objective：This article provided a membrane-coveredultra-compliance segmented stent which is recyclable, and its structure and methods of preparationhad been introduced. The stent included an independentinner membrane and an independentouter membrane. The inner membranewas separated from the segments part with a space for the relative shiftand itcould still fit bodyduring the bending. The outer membrane made the stent could be bended to various angleseasily. The stentwasultra-flexible and could adapt to the physical structure of the body lumen very well, so that it could reduce serious complications greatly,such as luminal hyperplasia, perforation and bleeding.
