I've read a couple of intriguing articles about a robotic/artificial pancreas, and it seems hopeful for the near future. There's a great article in Wired Magazine this month here , and and another article from the LA Times here about Boston researchers who are using a combination of insulin & glucagon in their trial pancreas. They seem to think that something can be on the market in as little as 7 years.
We have the technology. All the pieces just have to be put together. It's very exciting. I hope that when it all comes together, that health insurance companies will make such devices available and affordable.
Also, although the technology is wonderful, an artificial pancreas is still not a CURE! So let's keep working on that, eh?
