There are different levels of approval for medical devices in the US.
The lowest level would be for something like crutches, which can't
really hurt the patient unless you do something really dumb, so you
basically prove that you followed established practices instead of doing
something dumb.  More invasive devices like pacemakers or ventilators
need much more intense testing and approval.  One thing I remember being
told was that you have to document the design and development (including
the software) every step of the way.  There was a guy here on
c.a.e. some years ago who did that stuff and I learned some things from
him.  It is one of the reasons I got interested in Ada.
