Paradigm ambulatory insulin infusion pumps.
Manufactured by Medtronic.
Models: MMT - 511, 512, 712, 712E, 515, 715, 522, 722, 722K, 523, 723, 723K, 554 (VEO) and 754 (VEO).
Problem
Risk of compromised insulin therapy, which may lead to severe hypoglycaemia (low blood glucose) or severe hyperglycaemia (high blood glucose). The root causes are:
- Loose drive support cap (all models)
- Damage to pump if immersed in water (all models)
- Programming issue related to the sensor graph timeout (Paradigm VEO MMT-554 and MMT-754 only).
-
Loose drive support cap:
Medtronic has received a report of a serious injury related to a loose drive support cap. This may become detached from the pump case, due to impact damage. An attempt to press back the drive support cap may result in an unintended delivery of insulin. -
Water damage:
This may result in a pump alarm or may cause the buttons to stop working. -
Sensor graph timeout:
This issue only applies to Paradigm VEO (MMT-554 and MMT-754) pump users who are also using both Medtronic ‘Continuous Glucose Monitoring’ and the ‘Low Glucose Suspend’ feature.
Paradigm VEO is equipped with a ’Low Glucose Suspend’ feature, which will automatically suspend insulin delivery when glucose levels are too low, to help reduce the risk of severe hypoglycaemia. Basal insulin delivery may not resume in time if the pump user has the ‘Low Glucose Suspend’ feature enabled and has changed the sensor graph timeout setting to “NONE” from the default setting of two minutes. This could result in hyperglycaemia.
Action
- Identify affected devices.
- Ensure that all staff and patients receive a copy of Medtronic’s
- Discontinue pump use if drive support cap is loose and contact the manufacturer.
- Do not immerse the pump in water.
- Regularly examine the pump for damage, especially after a shock or drop.
- For Paradigm VEO models, check that the default setting for the sensor graph timeout is not ‘NONE’, if the ‘Low Glucose Suspend’ feature is used.
