Medtronic recalls Paradigm REAL-Time Insulin Pumps (MMT-522, MMT-722) due to potential insulin over- or under-delivery when pump height changes, risking severe hypoglycemia or hyperglycemia.
All Medtronic MiniMed infusion pumps (Paradigm series, 600 series, and BLE 700 series) were found to be affected by unintended over- and under-delivery of insulin when the pump is elevated or lowered relative to the infusion site, respectively, because of changes in gravitational force impacting hydrostatic and hydrodynamic pressures. Insulin over-delivery, which can occur when the pump is elevated relative to the infusion site, can result in severe hypoglycemia, altered mental status, seizure, coma, or death. An under-delivery of insulin, which can occur at lowered pump height conditions relative to the infusion site, can result in severe hyperglycemia, dehydration, diabetic ketoacidosis, or death.
Medtronic is recalling its Paradigm REAL-Time Insulin Pumps (MMT-522 and MMT-722 models) because moving the pump up or down relative to the body can cause incorrect insulin delivery. This could lead to life-threatening low blood sugar or high blood sugar levels.
When the pump is elevated above the infusion site, it can deliver too much insulin, causing severe hypoglycemia (dangerously low blood sugar) that may lead to seizures, coma, or death. When the pump is lowered relative to the infusion site, it can deliver too little insulin, causing severe hyperglycemia (dangerously high blood sugar) that may lead to dehydration, diabetic ketoacidosis, or death.
People using Medtronic Paradigm REAL-Time Insulin Pumps (MMT-522 or MMT-722 models) are affected. Those with diabetes who rely on these pumps for insulin delivery are most at risk.
Check for the pump model numbers MMT-522 or MMT-722. These pumps were sold with specific part numbers listed in the recall notice.
Ensure the pump is at the same level as the infusion site when using it to prevent incorrect insulin delivery.
The affected models are Medtronic Paradigm REAL-Time Insulin Pumps with part numbers MMT-522 or MMT-722.
Moving the pump up or down relative to the infusion site can cause incorrect insulin delivery, potentially leading to severe hypoglycemia or hyperglycemia, which may result in life-threatening conditions.
No, but you should check the pump's height relative to the infusion site to avoid incorrect insulin delivery. The recall does not require immediate discontinuation.
