Minimed 780G with Smart Guard
Syringe and Vial
Summary
The Medtronic MiniMed™ 780G system is designed with SmartGuard™ technology, which can help with the occasionally missed meal or inexact carb counts. It provides automatic basal adjustments to manage glucose levels to a prespecified target (100 mg/dL [5.5 mmol/L], 110 mg/dL [6.1 mmol/L], or 120 mg/dL [6.7 mmol/L]) and auto correction bolus, every 5 minutes. The advanced hybrid closed-loop system uses current and past glucose trends from the Guardian™ 4 sensor to detect a rapid rise (e.g., a missed meal) in sensor glucose. No fingersticks required when the SmartGuard™ feature is active.
Traditional syringe and needle. The most affordable insulin delivery option.
Components
Infusion Set
An infusion set contains the thin plastic tubing that delivers insulin from the pump to the body.
Controller
Pump receives CGM readings and automatically adjusts insulin delivery. Data from the pump and CGM viewable on compatible smartphones.
Sensor
Sensor is inserted underneath the skin, either on the abdomen or arm.
Pump
Pump connects tubing to a small patch called an infusion set that attaches to the body.
Needles
Classic syringes with plunger used to fill insulin for injection
Long-acting insulin
Basal (long-acting) insulin vial for steady release of insulin that helps control blood sugar between meals, and overnight.
Rapid-acting insulin
Bolus (fast-acting) insulin vial for meal time or high blood sugar correction.

Patient Considerations
Active Lifestyle
Temp Target. Manually increase blood sugar target range to 150 mg/dl during activity. Temp target can run 30 minutes to 24 hours in 30-minute increments. Auto corrections are disabled. The pump is not waterproof.
Limited Adjustability. No way to adjust long-acting insulin for higher activity on the fly.
Avoiding Highs and Lows
Customizable auto-bolus. Auto-correct bolus corrects highs if carb counts are miscalculated or bolus is occasionally missed. The system aims to maintain a target blood glucose level between 100 mg/dL and 120 mg/dL depending on personalized target glucose settings. Auto-bolus is available every 5 minutes to correct blood sugar between 100 mg/dL and 120 mg/dL (12 corrections per hour). Automatic insulin delivery settings are adjustable.
Limited customizability. Requires a high level of engagement and effort to avoid highs and lows but can be paired with a CGM for improved blood sugar control.
Comfort
Somewhat comfortable. Medtronic sensors need more tape than other sensors. Largest pump option.
Many components. Must carry insulin vials and large syringes but nothing attached to the body.
Easy Insulin Dosing
Automatically adjusts settings. Automatically adjusts insulin to reach personalized target between 100 mg/dL and 120 mg/dL. Will automatically revert to manual mode in certain situations. Basal and bolus in 0.025 increments. Extended bolus unavailable when using automated insulin delivery mode.
Requires attention. You have to do the math to figure out your dose. Unable to adjust basal in real-time.
Easy to Use
Easy software. Software makes many dosing decisions. Can be difficult to keep automatic insulin dosing features working. Requires fewer parts than do-it-yourself systems.
Many steps. Requires effort to figure out doses and deliver insulin every single time you need it.
Fewer Fingersticks
Factory-calibrated sensor. Fingersticks needed for backup only.
Frequent finger-sticks are required.
Privacy
Somewhat discrete. Ability to check blood sugar on phone or watch. Pump has tubing but can be clipped to clothing or placed in a pocket to be discreet when needed.
Hideable. Vials and syringes can be hidden when not in use but very visible when in use. Frequent injections are unavoidable.
