"A “bionic pancreas” that uses a smart phone, glucose monitor and insulin pump to automatically control blood sugar levels helped more than two dozen people live free of finger pricks and other troublesome reminders of diabetes"
What's more, the new device was actually better at controlling symptoms than the patients themselves. It's designed primarily for the roughly 1.5 million Americans who have Type I ("Juvenile") diabetes.
It's also get an extra feature: "it delivers another hormone called glucagon, which brings blood sugar back up when it’s too low."
The device uses BlueTooth technology to control a set of insulin pumps on and in the abdomen. It's currently in the trial stage, but certainly seems promising.
The system is specifically designed for use with an iPhone (4 and above); no word yet on whether there'll be an Android version, as well.
