Hybrid Closed-Loop Hotel Studies With Medtronic PID Controller

Study participants will be asked to use the CGM and the study insulin pump provided for approximately 4 to 5 days prior to initiation of the HCL PID-IFB system in a hotel setting for another 4 to 5 days. All participants with diabetes and the parent/ guardian of participants \< 18 years of age will be asked to stay overnight in a hotel while the HCL PID-IFB system is on and to remain close to Stanford University during the day. For participants \> 18 years of age, designated remote monitors will be asked to receive alerts for low/ high glucose levels. Enrolled participants will be asked to complete evaluations to describe their user experience/ evaluation of the system.Each participant had a companion (parent/ legal guardian of participants \< 18 years of age, or the designate remote monitor for participants \> 18 years of age) who will consent to monitor the participant and complete an evaluation, but will not be considered enrolled in the study.
