I wonder if you're aware of the rigorous testing standards for medical implant devices in the us?
Basically you can cobble anything together, and if you can successfully claim it was 'based upon' a formerly tested design, you don't need to do any testing at all. You just put it on the market, and surgeons start implanting it.
