It's worth noting that the pancreas produces more than insulin, though that's the most common failure. Cystic Fibrosis patients have scarring/blocking of the pancreas that results in malnutrition due to inadequate delivery of digestive enzymes. (CF is known as a lung disease, but earliest diagnoses, when patients died early enough to not develop lung issues yet, were due to malnutrition and autopsies reveal cysts and fibrotic tissue on the pancreas - "cystic fibrosis of the pancreas" in earliest writings)<p>Just a long-winded way of being pendantic and saying this couldn't be an artifical pancreas, but just perform one of its roles :-)
