Medtronic have identified a risk of compromised insulin therapy when using Paradigm ambulatory insulin infusion pumps, which may lead to severe hypoglycaemia or severe hyperglycaemia.
Which models are affected?
MMT - 511, 512, 712, 712E, 515, 715, 522, 722, 722K, 523, 723, 723K, 554 (VEO) and 754 (VEO).
What are the issues with this pump?
Issue #1 - Loose drive support cap (all models)
The pump’s drive support cap holds the pump motor in place and allows the motor’s piston to press against the reservoir to deliver insulin.
In rare cases, the cap may stick out from the bottom of the reservoir compartment. This condition can occur when the pump is damaged due to impact with a hard surface (for example if it is dropped). If the loose drive support cap is pressed on it could result in the unintended delivery of additional insulin.
What you can do about this
Regularly examine your pump, especially if you have dropped it at any point.
Discontinue pump use if drive support cap is loose; do not press on this portion of the pump; and contact the manufacturer.
Issue #2 - Damage to pump if immersed in water (all models)
Exposure to water may result in pump alarm, damage of the pump’s internal electronics, or cause the buttons to stop working.
To swim or participate in other water activities, always disconnect from your Paradigm pump, and reconnect afterwards.
If you accidentally submerge your insulin pump in water, dry the pump quickly using a soft, clean towel. Verify that it is working properly by selecting Self-test from the insulin pump's Utilities Menu.
If you think your pump may be water damaged, check your blood glucose levels and treat with an injection and call the Medtronic help line for further assistance.
What you can do about this
Do not immerse the pump in water.
Issue #3 - Programming issue related to the sensor graph timeout (Paradigm VEO MMT-554 and MMT-754 only).
This information applies only to Paradigm VEO (MMT-554 and MMT-754) pump users who are also using Medtronic Continuous Glucose Monitoring and have the Low Glucose Suspend feature enabled.
Your Paradigm VEO insulin pump allows you to set the number of minutes to display the Sensor Graph before returning to the home screen.
The factory default setting for Sensor Graph timeout is set to two minutes. If the Sensor Graph timeout is set to “NONE” it can prevent the auto-resume of basal delivery two hours after a Low Glucose Suspend event, which can result in elevated blood glucose values.
This will only happen if you go to the Sensor Graph screen during a Low Glucose Suspend event, and leave that screen displayed. When this happens, the pump will beep three times every 15 minutes to remind you that insulin delivery has been suspended. All other alarms will function normally, but basal delivery will not resume as long as the Sensor Graph screen is displayed.
What you can do about this
For Paradigm VEO models:
Do not change the Sensor Graph timeout setting to “NONE.”
If you are using the Low Glucose Suspend feature and have changed the Sensor Graph timeout setting to “NONE,” please follow the steps below to reset it now:
Go to the Sensor Menu
Select Edit Settings, Press ACT
Select Graph Time Out, Press ACT
Select 2, 4 or 6 minutes (do not select “NONE”), Press ACT

If you are affected by this or unsure of what to do, speak to a member of your diabetes healthcare team.
