What are automated insulin delivery systems?

Learn about how AID systems work and why they are the standard of care for type 1 diabetes.1

MiniMed 780G system

Automated insulin delivery (AID) systems combine an insulin pump and continuous glucose monitor (CGM) to help people living with type 1 diabetes manage their blood sugar levels.

AID systems, also known as hybrid closed loop systems, can detect changes in a person’s sugar levels in real time and automatically adjust insulin doses in response.

AID systems for kids are available depending on what insulin pump therapy your healthcare provider may recommend.

How do AID systems work?

AID systems are made up of a CGM, an insulin pump, and a smart algorithm that links the two devices together, allowing them to “talk” to each other.

The CGM tracks your sugar levels every few minutes through a small sensor inserted under the skin.

Then the algorithm uses that data to tell your pump just the right amount of insulin to deliver. It may even tell the pump to stop sending insulin if your sugar levels are low.

While you still need to bolus before meals, the MiniMed™ 780G system is designed with SmartGuard™ technology that does the work in between. If your sugar levels are trending high, the system automatically gives you more insulin. If your sugar levels are trending low, the system automatically reduces the amount of insulin delivered.

What are the benefits of AID systems?

Advanced technology helps make diabetes management easier

That smart algorithm that allows the CGM and insulin pump to “talk” to each other does so much more than just send sugar level data.

The algorithm uses current and past sugar level trends to anticipate, adjust, and correct insulin delivery.

AID systems, like the MiniMed™ 780G system, help take the guesswork out of counting carbs. It uses Meal Detection™ technology* to detect any miscalculated or occassionally missed meal doses and then deliver a correction dose.

The standard in diabetes care

It’s no surprise why the American Diabetes Association calls automated insulin delivery systems the standard of care for people with type 1 diabetes. When your sugar levels are well-managed, it can help to:

The MiniMed 780G system

Not all AID systems are created equal. Only the MiniMed™ 780G system with Meal Detection™ technology* can automatically deliver correction boluses of insulin without any work needed from you, as quickly as every 5 minutes.§

People typically choose AID systems to manage their diabetes because they want to focus more on living life and less on micromanaging their therapy.

With the MiniMed™ 780G system, it works for you all day and night. In fact, 95 percent of customers felt more freedom from having to think so much about their diabetes.+^2

Important safety information: MiniMed 780G system with SmartGuard technology with Guardian 4 sensor

The MiniMed 780G system is intended for continuous delivery of basal insulin at selectable rates, and the administration of insulin boluses at selectable amounts for the management of type 1 diabetes mellitus in persons seven years of age and older requiring insulin as well as for the continuous monitoring and trending of glucose levels in the fluid under the skin. The MiniMed 780G system includes SmartGuard technology, which can be programmed to automatically adjust insulin delivery based on the continuous glucose monitoring (CGM) sensor glucose values and can suspend delivery of insulin when the sensor glucose (SG) value falls below or is predicted to fall below predefined threshold values.

The Medtronic MiniMed 780G system consists of the following devices: MiniMed 780G insulin pump, the Guardian 4 transmitter, the Guardian 4 sensor, One-press serter, the Accu-Chek Guide Link blood glucose meter, and the Accu-Chek Guide test strips. The system requires a prescription from a healthcare professional.

The Guardian 4 sensor is intended for use with the MiniMed 780G system and the Guardian 4 transmitter to monitor glucose levels for the management of diabetes. The sensor is intended for single use and requires a prescription. The Guardian 4 sensor is indicated for up to seven days of continuous use.

The Guardian 4 sensor is not intended to be used directly to make therapy adjustments while the MiniMed 780G is operating in manual mode. All therapy adjustments in manual mode should be based on measurements obtained using a blood glucose meter and not on values provided by the Guardian 4 sensor. The Guardian 4 sensor has been studied and is approved for use in patients ages 7 years and older and in the arm insertion site only. Do not use the Guardian 4 sensor in the abdomen or other body sites including the buttocks, due to unknown or different performance that could result in hypoglycemia or hyperglycemia.

WARNING: Do not use the SmartGuard feature for people who require less than 8 units or more than 250 units of total daily insulin per day. A total daily dose of at least 8 units, but no more than 250 units, is required to operate in the SmartGuard feature.

WARNING: Do not use the MiniMed 780G system until appropriate training has been received from a healthcare professional. Training is essential to ensure the safe use of the MiniMed 780G system.

WARNING: Do not use SG values to make treatment decisions, including delivering a bolus, while the pump is in Manual Mode. When the SmartGuard feature is active and you are no longer in Manual Mode, the pump uses an SG value, when available, to calculate a bolus amount. However, if your symptoms do not match the SG value, use a BG meter to confirm the SG value. Failure to confirm glucose levels when your symptoms do not match the SG value can result in the infusion of too much or too little insulin, which may cause hypoglycemia or hyperglycemia.

Pump therapy is not recommended for people whose vision or hearing does not allow for the recognition of pump signals, alerts, or alarms. The safety of the MiniMed 780G system has not been studied in pregnant women, persons with type 2 diabetes, or in persons using other anti-hyperglycemic therapies that do not include insulin.
