MiniMed Flex: a screenless pump, half the size, run from your phone
MiniMed’s smallest pump has US clearance and no screen at all. What it does, which sensors it pairs with, and the honest position on UK availability.
There is a new MiniMed insulin pump, and you cannot get it in the UK. American regulators cleared MiniMed Flex on 18 March 2026: about half the size of the 780G, no screen, run from a phone app.
- The FDA clearance covers the United States only, and no UK or European date has been announced.
- With no screen, the phone app is where you see your data and give a bolus (the insulin that goes with food).
- If your phone is flat or lost, the pump keeps delivering what is already programmed, but you need the app to bolus.
- It uses the same SmartGuard software as the 780G. The automation is not new; the smaller body is.
What has been cleared, and what is familiar about it
MiniMed, the diabetes business spun out of Medtronic in early March 2026, said on 18 March that the US Food and Drug Administration had cleared MiniMed Flex. It is about half the size of the MiniMed 780G, roughly two insulin vials stacked, with a 300-unit reservoir and the option of the company’s Extended infusion set, worn for up to seven days. In the US it is cleared for type 1 from age 7 and insulin-treated type 2 from 18.
What it does is not new. Flex uses SmartGuard, the same hybrid closed loop software as the 780G: pump and sensor work together, so the software handles your background insulin minute by minute, easing off when glucose is falling and topping up when it climbs. You still count carbs and tell it about meals. The aim is fewer hypos (glucose below 4 mmol/L) and less time high. Meal Detection is carried over too, picking up a fast rise after a meal that was missed or under-counted. At commercial launch, MiniMed says Flex will work with its Simplera Sync sensor and the Instinct sensor made by Abbott.
What a pump with no screen means on an ordinary day
On a 780G you can look at the pump. On Flex there is nothing to look at: MiniMed says the pump keeps you informed with lights, sounds and buttons, and the app is where you view your data, make changes and give boluses.
So the obvious question is what happens when the phone is not there. MiniMed answers it directly: if the pump loses its connection to the app, it carries on delivering insulin based on what is already programmed, and you need to connect back to the app to give a bolus or clear alerts. Anyone without a compatible phone can buy the company’s App Manager handset to use instead. So a flat battery is not an insulin emergency, but it does mean no bolus until you are back in the app, and supported-phone lists are model-specific, which matters more here than on a pump with its own screen.
Why you cannot get this here yet
An FDA clearance is a US decision and nothing more. MiniMed has described a customer experience phase in the spring with selected existing customers, a broader commercial launch in the summer, and a free upgrade for existing 780G users once Flex is on sale in the US. No UK or European availability has been announced for Flex at all.
What the company did announce for Europe, eight days earlier, was a different product: a CE Mark on 10 March 2026 for the 780G used with Abbott’s Instinct sensor, with launch in the first European countries expected in the summer. Reaching Great Britain needs its own regulatory sign-off, and NHS funding is a separate question after that. What is available now is the 780G and the other closed loop systems, through the five-year NHS rollout in England that began in April 2024, prioritising children and young people, people who are pregnant or planning a pregnancy, and adults already using a pump. Which of them your clinic can offer varies locally.

Questions that make an appointment useful
When it's urgent
Because a pump holds only rapid-acting insulin, an interruption to delivery is the one pump-specific emergency to know. If glucose is high and you feel unwell, check ketones if you can (the chemicals the body makes when it runs short of insulin) and contact your diabetes team or NHS 111. If someone is being sick, drowsy, breathing heavily or fast, has stomach pain or breath that smells fruity alongside a high reading, that can be DKA (diabetic ketoacidosis, a dangerous emergency): call 999 or go to A&E straight away, and never let testing delay the call.
