WASHINGTON (AP) — Federal regulators have approved a first-of-a-kind "artificial pancreas," a device that can help some diabetes patients manage their disease by constantly monitoring their blood sugar and delivering insulin as needed. Type 1 diabetes patients now have to manage their insulin through multiple injections throughout the day or a drug pump that delivers it through a tube. Older insulin pumps simply deliver a baseline level of insulin, and patients must monitor their sugar levels and give themselves more insulin to keep their blood sugar from getting too high.
