During this study, the investigators would like to evaluate the intra-peritoneal insulin delivery as a potential breakthrough method for delivering insulin within the artificial pancreas system.~The intent is to exploit the rapid action achieved by IP insulin to compensate for meals and for management of the basal insulin needs. Patients will come for two closed-loop admissions of 24 hours. The first closed-loop will be performed using subcutaneous route, whereas the second one will be performed using the intra-peritoneale route.
The primary purpose of this pilot study is to test an artificial pancreas system which uses the intra-peritoneal (IP) route for insulin delivery in type 1 diabetic patients.
