The Medtronic MiniMed™ 670G is a type of insulin pump that works with your continuous glucose monitor (CGM for short). It’s the first insulin pump that uses new technology called a hybrid closed-loop system to treat Type 1 diabetes.
Is the MiniMed™ 670G an artificial pancreas?
No, the Medtronic MiniMed™ 670G and Medtronic monitors are called a hybrid closed loop system. They are not an artificial pancreas because they don’t work exactly like a human pancreas.
The 670G can mimic some functions of a pancreas but this doesn’t mean it’s a cure for diabetes. You’ll still need to do a finger-prick test when you eat or if you need a correction dose of insulin, and you’ll still need to carb count.
How the MiniMed™ 670G works
The hybrid closed loop system needs both the pump and a Medtronic CGM. The pump and your monitor work together to keep your blood sugar levels in target.
This pump won’t work with other brands of CGMs, it has to be a Medtronic CGM.
The MiniMed™ 670G can suspend your insulin when your glucose levels are dropping like some other pumps, but can also adjust the amount of insulin it gives you. Your CGM sends your blood sugar levels to the pump every five minutes. The pump then reacts by increasing or lowering the amount of insulin it gives you.
The pump has two modes, manual and automatic:
- Manual mode – you’ll need to set your basal rates yourself. The pump will alarm if you’re going too high or too low, and it will suspend your insulin if you’re going really low.
- Auto mode – the pump will give you your basal insulin automatically depending on the readings from your CGM.
The Medtronic CGM isn’t licensed to dose in the UK, so you’ll still need to finger prick and input the number of carbs you’ve eaten or drunk even if the pump is in auto mode.
The MiniMed™ 670G needs to be calibrated regularly, so you’ll need to do a finger-prick test. It will also ask you to do a blood check at times to make sure it’s still working safely.
How to get the MiniMed™ 670G pump?
The pump can be used by people with Type 1 diabetes who are over the age of 7 and takes at least 8 units of insulin a day. You’ll also have to meet the national guidelines and criteria. But this pump isn’t recommended if you’re pregnant.
If you’d like to use the Medtronic 670G pump, talk to your diabetes nurse or doctor. They’ll be able to talk you through the system if it would be right for you and how you might be able to get it.
Will the MiniMed™ 670G be funded on the NHS?
Some areas in the UK are providing the system on the NHS, but it's not a guarantee that your local area will fund it. Check with your diabetes nurse or doctor to see if it's available and if you meet the criteria for a pump or CGM.
Clinical criteria for both insulin pump and CGM systems can be found in NICE guidelines and local policies are in place for funding.
If funding isn't available for you, you can self-fund the MiniMed™ 670G and a CGM. To find out more about self-funding and any support on offer, visit the Medtronic website.
To self-fund a Meditronic device you'll still need to be supported by your healthcare team, so talk to your doctor or nurse if you want to know more about this option.
