Medtronic recalls MiniMed 640G insulin pumps (MMT-1711 to MMT-1752) due to potential insulin over/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 MiniMed 640G insulin pumps (model numbers MMT-1711 to MMT-1752) because elevating or lowering the pump relative to the infusion site can cause incorrect insulin delivery. This may lead to life-threatening low blood sugar or high blood sugar levels.
The pump can deliver too much or too little insulin when its height changes compared to the infusion site. This happens because gravitational forces affect insulin delivery. Over-delivery can cause severe hypoglycemia (dangerously low blood sugar), which may lead to seizures, coma, or death. Under-delivery can cause severe hyperglycemia (dangerously high blood sugar), which may lead to dehydration or diabetic ketoacidosis.
People with diabetes who use Medtronic MiniMed 640G insulin pumps (model numbers MMT-1711 to MMT-1752) are affected. Those who have the pump elevated or lowered relative to their infusion site are at higher risk.
Check if your pump has model numbers MMT-1711, MMT-1712, MMT-1751, or MMT-1752. These pumps were sold with specific serial numbers listed in the recall notice.
Ensure the pump is at the correct height relative to your infusion site to avoid insulin delivery issues.
Check your blood sugar levels frequently to detect signs of hypoglycemia or hyperglycemia.
No, the recall does not require immediate discontinuation. However, you should check the pump height and monitor blood sugar levels closely.
The affected models are MMT-1711, MMT-1712, MMT-1751, and MMT-1752.
Your pump is at risk if it has model numbers MMT-1711 to MMT-1752, as listed in the recall notice.
