Since many factors can affect your glucose levels, such as diet, exercise and stress levels, you may need a system that can give you better control: an intelligent system.  The MiniMed™ 640G system features innovative technology to more closely mimic the way a healthy pancreas delivers basal insulin to the body in order to help you to achieve better control. 

SMARTGUARD™: One step closer to The Artificial Pancreas

Tired of experiencing unexpected lows? Worried about hypos? To avoid low glucose levels and maintain good glucose control, it is important to know where your glucose levels are and where they are heading.  The MiniMed 640G system is designed to help protect you, so you can feel more secure.  SmartGuard, our exclusive technology, mimics some functions of a healthy pancreas to provide advanced protection against hypoglycaemia.4*

  • Based on your sensor glucose values, SmartGuard can predict when you are approaching low glucose levels 30 minutes in advance and automatically stop insulin delivery**
  • When your glucose levels recover, SmartGuard will automatically resume insulin delivery***.
  • You have the possibility to set multiple low limits throughout the day to give you increased protection when you need it most.

 Dynamically stopping insulin delivery with a suspend feature can significantly reduce the number of hypoglycaemic events.4

93% of those who used a suspend feature in their pump felt more secure managing their diabetes.5

MiniMed 640G SmartGuard

*The dynamic suspend feature is based on certain criteria: sensor glucose must be within 3.9mmol/L of the low limit and predicted to be 1.1mmol/L above the low limit within 30 minutes AND the pump must not be in the refractory period. **The dynamic resume feature is based on certain preset criteria: sensor glucose must be 1.1mmol/L above the preset low limit and predicted ot be 2.2mmol/L above within 30 minutes AND insulin must have been suspended for at least 30 minutes.

MiniMed 640G also has some other integrated intelligent features for increased protection, such as:

  • Active insulin tracking, so the insulin still working in your body is displayed on the pump screen and taken into account in the Bolus Wizard recommendation
  • Bolus progress bar, allowing you to see the amount of bolus insulin being delivered; and Stop Bolus, to easily stop a bolus at any time
  • Predictive battery end of lifeso you know when your battery will run out before it happens

  • ****Calculation is based on the amount of insulin currently in the body, the amount of carbohydrates, the user’s current and target blood sugar levels, their insulin-to-carb ratio and their body’s sensitivity to insulin. Proper Bolus Wizard set-up must be completed first. Users must input the number carbohydrates they are eating and their current Blood Glucose value before the Bolus Wizard can calculate the insulin users should take.
  • Waterproof at time of manufacture up to 3.6 meters for up to 24 hours at a time. See MiniMed 640G User Guide for a complete description of the waterproof capabilities and proper use instructions.
