The MiniMed 508 problem was fixed last November. The problem had no effect
on the safety or general reliability of the pump. It was a nuisance only.

Actually, the MiniMed 508 is also waterproof for the important parts. The
drying precautions are just that -- precautions.

The D-tron will not have a second pump in the package. The second pump
procedure came from Swiss law (D is a Swiss company) which requires a backup
system be constantly available in case of failure of any potentially life
saving equipment. It never was for altruistic reasons.

MiniMed has been working on such a system for over a year. Early tests with
dogs have shown a high level of success. One person whose son works for a
medical research organization (I don't know which one) has told me that one
has been implanted in at least one human being. Since I haven't been able
to substantiate this, it's best to consider it a rumor at this point.
> 2 not waterproof and must disconnect
Not entirely true. While MiniMed *does* say that if the internal part gets
wet by dropping into a bathtub, for example, to remove the reservoir and dry
it out. This is precautionary. The internal circuitry, motor, etc., is all
inside a waterproof case.

The MiniMed 508 allows a setting for more dilute insulin (e.g. 50 u per ml).
Lilly is working to develop a buffered Humalog specifically for use in
pumps. Can you document the occlusion problems? Why would MiniMed have
this problem with occlusion due to the Humalog while the Disetronic not?
This sounds more like an argument to use regular insulin instead of Humalog
than an issue of which pump to choose.

According to the MiniMed people here in Atlanta, one should arrive by the
earliest FedEx delivery available.

The accuracy is approximately the same as for a blood glucose monitor --
that is it meets the criteria for waived laboratory tests under the Clinical
Laboratory Improvement Amendments of 1988 (CLIA 88) as do *all* commercially
available home test meters. The difference is in the lag time between blood
glucose and interstitial fluid glucose, which is not yet well documented
(This lag time is the reason for the delays in the availability of the
GlucoWatch system which also measures interstitial cell glucose, not blood
glucose). The $5000 price tag includes two CGMS units, the comm unit,
software, and support. Sensors are $30 each. The purpose of the CGMS is
*not* to replace regular testing but to better see the diurnal trends in
one's control. Further, there is no way to get real time readings from the

Only half? Are you suggesting that Disetronic doesn't do the same?
Actually, I get the reservoirs separately from the infusion kits. I suppose
I could order half the number of reservoirs, etc. I know the Silhouette
kits can be ordered as complete or what they call "combo" with twice the
number of cannulas as tubing sets. Not much difference in price, though.

And that is probably the best reason to choose the Disetronic, particularly
for children (and others) who are very insulin sensitive.

How was it settled? Was there any admission on MiniMed's part? Why did
Disetronic drop the suit? Without this information, your sentence is mostly
innuendo, and is quite defaming.

I suggest that if there is substantiation of these allegations that they be
made public. These are serious charges, and could impact many of us if they
The bottom line, IMHO, is that both pumps are useful devices, and the Animas
pump will be as well. Most of the choice of one pump over the other comes
down to personal preference on someone's part. There is no fundamental
difference in what they do -- deliver measured doses of insulin in a
reliable, programmable way.
