Feb. 13, 2020 -- One person has died and more than 2,000 have been injured by malfunctioning insulin pumps that are now part of a federal recall.

The FDA announced the recall of two types of Medtronic brand MiniMed insulin pumps used by patients with Type 1 diabetes. They are:

  • Model 630G (MMT-1715), all lots before October 2019 and distributed from September 2016 to October 2019
  • Model 670G (MMT-1780), all lots before August 2019 and distributed from June 2017 to August 2019

More than 300,000 devices are included in the recall.

Medtronic says the malfunctioning pumps are missing or have a broken retainer ring, which helps lock an insulin cartridge in place. Without this ring, or if it’s broken, the pump may deliver too little or too much insulin, both of which can lead to problems known as hyperglycemia or hypoglycemia, respectively. Severe hyperglycemia or hypoglycemia can make you pass out or lead to seizure and death.

Medtronic began directly notifying patients and doctors on Nov. 21, 2019, that there were potential problems with the pumps. But the recall was just announced this week.

Anyone with questions should call Medtronic at 877-585-0166. The line is open 24 hours a day, the company says.
