The progress towards a closed loop system or "artificial pancreas" has steadliy grown. Two of the devices, the Dexcom and the Medtronic Guardiat RT have recieved FDA approval for patients over the age of 18. These continuous blood glucose monitors are expensive, but people that we know who have used them swear by them. Especially when you live with the daily fear that accompanies impaired hypoglycemic awareness (not being able to tell when your blood sugar is dangerously low).
A third promising entrant into the mix is Abbott's Freestyle Navigator. FDA approval is expected in the Fall of 2006. A handy comparison chart can be viewed at the Children with Diabetes website. Click here to check out the side by side comparison.
