You are invited to participate in a research study for the development of an artificial pancreas. An artificial pancreas uses a program which takes information from a continuous blood glucose monitor and uses that information to tell an insulin infusion pump how much insulin to deliver. The primary purpose of this study is to gain experience with insulin delivery algorithms or programs program (algorithm) provides the best regulation of glucose levels so that there are no severe low blood glucose reactions and blood glucose levels are generally between 70 to 180 mg/dl.

Exclusion Criteria:
  1. Exclusion Subjects who meet any of the following criteria are not eligible for the study: 1. The presence of a significant medical disorder that in the judgment of the investigator will affect the wearing of the sensors or the completion of any aspect of the protocol. 2. The presence of any of the following diseases: - Asthma if treated with systemic or inhaled corticosteroids in the last 6 months - Cystic fibrosis - Other major illness that in the judgment of the investigator might interfere with the completion of the protocol Adequately treated thyroid disease and celiac disease do not exclude subjects from enrollment 3. Inpatient psychiatric treatment in the past 6 months 4. Current use of oral/inhaled glucocorticoids or other medications, which in the judgment of the investigator would be a contraindication to participation in the study. 5. Pregnancy, breast feeding, or intention of becoming pregnant in the next 2 months. 6. Weight less than 26 kg 7. Renal failure or peritoneal dialysis 8. History of heart disease 9. The use of beta-blockers 10. History of cerebrovascular disease, or non-hypoglycemic seizures, or intolerance of glucagon treatment. 11. History of a hypoglycemic seizure within 6 months of enrollment.
