The upgrade process for any pump, whether or not it is minimed, is
under FDA scrutiny. This means that the company must put the pump
through it's entire certification procedure before it is returned to
the owner. It's not as simple as changing out some software code. The
regulatory layer that has been added require a great deal of
documentation and tracking that is not required of ordinary
electronic appliances and it costs $$.
A good example of this is the aircraft industry. Light planes use
many components that are identical to ones used on autos, the only
difference being that they are "certified" for aircraft use. That
means that there is a paper trail through the entire manufacturing
and distribution channel so that a failure can be traced to its
origin. i.e. About 20 years ago BC (before children) when I had a few
bucks, I co-owned a plane with 2 other guys. We had to replace the
alternator and purchased a new one that was identical to the one in
my car. It cost 3 X as much as the same alternator purchased at the
local auto supply (I checked), simply because it was certified for
What's the point of this.... there is a significant overhead to
manufacturing medical devices that is entirely regulatory. I'm not
making commentary on whether or not is is needed (I think most of it
is), only that it costs money and we get to pay for it.
