What Happened?

Medtronic revealed that the insulin pumps in question had a missing or broken retainer ring. This ring is supposed to lock the insulin cartridge in place so that it can function properly. In the malfunctioning units, users were receiving the wrong dosage of insulin, sometimes resulting in dangerously elevated blood sugar.

For people with Type 1 diabetes, it is very important to maintain healthy, controlled levels of blood sugar by using insulin. Severe hyperglycemia (elevated blood sugar) can lead to the person experiencing seizures or even death. That appears to be the case with the death involved in this recall.

What You Should Do

Although Medtronic contacted customers and healthcare providers in November about this issue, the FDA has just now released the details of the recall. If you didn’t receive a notice, however, don’t assume that you are unaffected.

The FDA and Medtronic recommend that users of this insulin pump should check to see if the retainer ring appears to be in one piece. If it seems to be damaged in any way, they should contact their doctor and stop using the pump.

Medtronic will provide a replacement pump for affected customers. You can contact the company’s 24-hour hotline at 877-585-0166.
