    • A medical device implant made with a shape-memory material is originally produced in a “permanent” configuration. The implant is then “programmed” into a temporary (typically smaller sized) configuration to facilitate implantation, after which, an external stimulus activates the implant to return to its permanent configuration. Apparatus and methods include inserting a first portion of the implant into an aperture of a compression fixture base, heating the implant, and then driving and compressing the remaining portion of the implant, which has a different, typically larger profile than that of the first portion, into the aperture with a compression fixture cover to “program” the remaining portion. The resulting programmed implant has first and remaining portions that have identical, or substantially identical, profiles.
    • 用形状记忆材料制成的医疗器械植入物最初是以永久性构造制成的。 然后将植入物编程为临时(通常较小尺寸)的构造以便于植入,此后外部刺激激活植入物以返回其永久构型。 装置和方法包括将植入物的第一部分插入到压缩固定基座的孔中,加热植入物,然后驱动和压缩植入物的剩余部分,其与第一部分具有不同的,通常较大的轮廓 进入具有压缩夹具盖的孔中以对剩余部分进行编程。 所得到的编程植入件具有第一和剩余部分,其具有相同或基本相同的轮廓。
