Considering how primitive the tech looks, someone could surely reverse-engineer it... but good luck trying to get funding for it and trying to find surgeons willing to take the risk of it blowing up in their face, because they will inevitably take the blame for any "bug" the tech could have :) The old doc was probably brave enough to do it while circumventing the whole regulatory process and using his personal reputation and charisma and professional relationships to pull it through and get the funding he needed, so again, good luck finding anyone to replace him.
