This seems like a problem long-term support contracts and medical insurance should be able to make a non-issue. Obviously, if someone undergoes an experimental medical treatment, the company performing the test should bear the responsibility of paying to have it removed should they go out of business or when the trial ends. If for some reason the company is unable to pay for corrective medical treatments, they should be required to have insurance. I'm not sure what the current rules and regulations are when it comes to this sort of stuff, but it really feels like all that's needed is a minor tweak so people do the sorts of things they should have been doing all along: planning financially and medically for the entire lifetime of the implant using the ethical rules and financial instruments we've already invented for dealing with risk and responsibility.
