Medtronic recalls MiniMed 530G insulin pumps (MMT-551, MMT-751) due to potential insulin over- or under-delivery when pump height changes, risking severe hypoglycemia or hyperglycemia. Affected units may cause life-threatening blood sugar issues.
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 530G insulin pumps (model numbers MMT-551 and MMT-751) because moving the pump up or down relative to the body can cause dangerous insulin delivery errors. This could lead to severe low blood sugar (hypoglycemia) or high blood sugar (hyperglycemia), which may cause coma or death.
When the insulin pump is elevated above the infusion site, it can deliver too much insulin, causing severe low blood sugar that may lead to coma or death. When the pump is lowered below the infusion site, it can deliver too little insulin, causing severe high blood sugar that may lead to dehydration or diabetic ketoacidosis.
People with diabetes who use Medtronic MiniMed 530G insulin pumps (model numbers MMT-551 and MMT-751) are affected. Those who have recently adjusted the pump's height relative to their body are at higher risk of blood sugar complications.
Check for model numbers MMT-551 or MMT-751 on the pump's label. These pumps were sold with specific user guides and FDA comments in the United States between 2019 and 2023.
Ensure the pump is at the correct height relative to your body to prevent insulin delivery errors.
Watch for signs of severe hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar) after adjusting pump height.
Moving the pump up or down relative to your body can cause it to deliver too much or too little insulin, leading to life-threatening blood sugar issues.
The affected models are MMT-551 and MMT-751.
No, but you should check the pump's height relative to your body and monitor for blood sugar changes.
