Development and the safety test of next-generation self and balloon expandable drugs eluting stent

对下一代支架进行了基础研究。探讨截肢残端内膜增生的处理方法。提出了改变端件形状的程序、改变镍钛诺管厚度的方法、仅对肢体部分进行强力抛光的程序、通过热处理改变记忆的方法等。使用铌作为支架材料无法在活体中进行安全性测试，但目前无法鉴定。此外，金属材料和考虑到安全性的处理程序正在研究中。

Fundamental research of the next-generation stent was done. The treatment method of intimal hyperplasia in the amputation stump section was examined. The procedure of changing the form of an end piece, the method of changing the Nitinol pipe thickness, the procedure of carrying out polishing strong only against the limb section, the method of changing the memory by heat treatment, etc. were proposed. Using niobium as stent material cannot perform a safety test in the living body, but the identification of itis impossible at present. Furthermore, the metal material and the treatment procedure of having taken safety into consideration are under examination.
