Description of intervention(s) / exposure
Treatment: Devices - 670G and 770G Insulin Pump
Treatment: Devices - Subject's Current Diabetes Therapy
Experimental: Hybrid Closed Loop Arm - The HCL Arm will use the MiniMed System (i.e., using Auto Mode) for 6 months during the study period.
Active comparator: Control Arm - The Control Arm will use individual subject's current diabetes therapy: CSII (Continuous Subcutaneous Insulin Infusion), MDI (Multiple Daily Injections) or SAP (Sensor Augmented Pump). Each cohort (CSII, MDI, or SAP) will be used as the control arm to be compared to the experimental arm (HCL).

Summary
Brief summary
The purpose of this study is to evaluate the safety and effectiveness of the Hybrid Closed Loop system (HCL) in adult and pediatric patients with type 1 diabetes in the home setting. A diverse population of patients with type 1 diabetes will be studied. The study population will have a large range for duration of diabetes and glycemic control, as measured by glycosylated hemoglobin (A1C). They will be enrolled in the study regardless of their prior diabetes regimen, including using Multiple Daily Injections (MDI), Continuous Subcutaneous Insulin Infusion (CSII) or Sensor-Augmented Pump therapy (SAP)
