In order for people with diabetes to stay healthy, they must continually check their blood sugar and adjust it with insulin or snacks. Medtronic aims to render this tedious process obsolete with its MiniMed 670G, a.k.a. the “artificial pancreas,” which has been in development for years but was only recently approved by the FDA. (It will be commercially available next year.) Once users attach the iPod-size device to their body, it measures their blood-­sugar levels every five minutes, providing more insulin or withholding it as needed. For now, they still need to manually request a dose after they eat. But Medtronic is working on a fully automated version, which Fran Kaufman, chief medical officer of the company’s diabetes group, says she hopes will help the 1.25 million people living with Type 1 diabetes “spend less time managing their disease and more time enjoying life.”
