Just got off the phone with CCS medical. Son's 522 is coming out of warranty so it's time to get a new pump. This is the one that was just approved by the FDA 2-3 weeks ago. I'm willing to try it and since we've met our insurance deductible for the year, we're paying almost nothing. OMG, I'm so excited! We had the CGMS from Medtronic a few years ago and it was awful. I switched to Dexcom and was much happier, but I must say, even with the new one we got earlier this year, sometimes his sugar is 100 points off of what the sensor says it is. Anyway, the next step after this will be a pump that delivers glucagon .. but I guess that's a few years away.
