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. |
