A bionic pancreas aims to take the math out of managing type 1 diabetes

Beta Bionics’ system, the iLet bionic pancreas, takes one more step toward full automation. Instead of reporting carb counts, users input whether an upcoming meal has more, less, or the same number of carbs than normal. “Then the system learns what they mean by that, how much insulin they need, and it will automatically give a portion of that insulin upfront in response to that announcement,” said Massachusetts General Hospital’s Steven Russell, who co-developed the system before it was licensed to Beta Bionics.
