Medtronic recalls MiniMed 620G insulin pumps due to potential insulin over- or under-delivery when pump height changes, risking severe hypoglycemia or hyperglycemia. Affected units have specific serial numbers.
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 620G insulin pumps because moving the pump up or down relative to the body can cause incorrect insulin delivery. This may 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 or death. When the pump is lowered below the infusion site, it can deliver too little insulin, causing severe hyperglycemia (dangerously high blood sugar) that may lead to dehydration or diabetic ketoacidosis.
People with diabetes who use MiniMed 620G insulin pumps are affected. Those who have recently moved the pump relative to their body are at higher risk.
Check for the following serial numbers: 643169559745, 643169721319, 763000375461, 763000253189. The pump model is the MiniMed 620G Insulin Pump (MMT-1750).
Ensure the pump is at the same level as the infusion site when using it to avoid incorrect insulin delivery.
Check blood sugar levels more frequently to detect potential issues early.
Elevating the pump above the infusion site can cause insulin over-delivery, leading to severe hypoglycemia, seizures, coma, or death.
Lowering the pump below the infusion site can cause insulin under-delivery, leading to severe hyperglycemia, dehydration, or diabetic ketoacidosis.
Affected pumps have serial numbers: 643169559745, 643169721319, 763000375461, or 763000253189.
