OBJECTIVE: To develop a closed-loop system that enables automated tight glycemic control by integrating glucose sensor data with drug infusion pump technology through a novel control algorithm.
The development of this drug delivery device that responds to glucose concentrations to automatically avoid both high and low blood glucose, a so-called artificial endocrine pancrease, has been a long-term goal of diabetes therapy. Although it is well known that people with diabetes do not make enough insulin, it is also true that their pancreas does not release glucagon, a blood-raising hormone, in response to hypoglycemia. Previous artificial pancreas designs did not include the capability to administer glucagon.
