I hope you make your MC someone smart enough to not have such advanced technology (Relative to his world) in the state he received... It would be interesting to see him try to create a bigger, more retrograde version of medical scanner equipment, or just the code used on the device - as it introduces the world to something so advanced without any explanation; tied to a newly created company (which is probably his case) would be a perfect recipe for disaster... With the military invading his house and everything...
