Medtronic MiniMed, Inc.: Guardian 4 Glucose Sensors Recalled for Inaccurate Insulin Delivery Risk

Agency Publication Date: February 7, 2024

Sign in to monitor this recall

Summary

Medtronic MiniMed, Inc. is recalling approximately 114,758 Guardian 4 Glucose Sensors because a manufacturing defect caused the protective coating on some sensors to be thinner than required. This defect can lead to inaccurate sensor glucose readings or a total loss of sensor function. If the sensor provides incorrect data to an insulin pump, it may cause the system to deliver too much or too little insulin, potentially leading to serious health complications. Consumers should verify if they have affected sensors by checking the model and lot numbers listed below.

Risk

A thin sensor coating can cause the device to report incorrect glucose levels, leading to the over-delivery or under-delivery of insulin. This poses a significant risk of hyperglycemia (high blood sugar) or hypoglycemia (low blood sugar), which can be life-threatening if not properly managed.

What You Should Do

  1. Check your sensor packaging for model numbers MMT-7040A, MMT-7040C1, MMT-7040C2, MMT-7040C3, MMT-7040D1, MMT-7040D2, MMT-7040MA, MMT-7040QC1, MMT-7040QC2, or MMT-7040QC3.
  2. Verify if your specific lot number is affected by comparing it against the list provided by the manufacturer, including lot codes such as HG72B2C, HG6RV7S, HG6RC39, HG73RNR, and others found on the product label.
  3. If you identify an affected sensor, stop using it immediately and contact Medtronic MiniMed, Inc. for further instructions regarding a replacement or resolution.
  4. Consult with your healthcare provider if you have used an affected sensor and are concerned about your glucose management or insulin dosing.
  5. Contact Medtronic MiniMed, Inc. directly for additional information or to report issues at their customer service channels.
  6. For further assistance, you can contact the FDA's medical device recall line at 1-888-463-6332 or visit www.fda.gov/medical-devices/medical-device-recalls.
