Re: Risk Management difference from CE
The FDA defines certain fundamental goals and terms differently than the authors of 14971. The FDA, for instance, to the best of my awareness does not state in any guidance that environmental risk is to be controlled, or technically define environmental harm. (Which, by the way, is a can of worms to try to do...and it doesn't work in the US legal system to say "I can't define it, but I know it when I see it.")
The FDA also includes veterinary medicine within its regulatory scope, whereas EC regulation of human medicine normally does not include animal medicine.
The FDA also defines only ambiguously that a risk assessment is expected to be part of a premarket notification in the first place. None of the several competing guidances within the sprawling FDA website that discuss the proper contents of a 510(k), specifically include an ISO 14971 risk assessment within their lists of required elements. But, in any verbal discussion of a 510(k) with an examiner, a risk assessment will be expected. You just have to know.
And, the FDA fairly clearly does not require that a risk assessment be done for most FDA Class I devices, even if provided to users in sterile form. That's not very consistent with the MDD classification approach, of course.
I'm sure there are other differences, but those are a few to consider.
