MiniMed™ insulin pump battery cap field safety notice

Medtronic have informed us that there is a potential issue relating to the battery cap on some Medtronic insulin pumps (including 640, 670 and 780 series pumps).

If the metal contact becomes loose or falls off from the battery cap, it can result in an incomplete battery connection, leading to no power source to the pump. When the pump detects no power source, an “insert battery” alarm will occur, and insulin delivery will immediately stop. After 10 minutes, the alarm sound may increase to a siren, and the pump will turn off.

What do you need to do?

• Check your battery cap during the next battery change. If the battery cap contact is not damaged, continue to use your pump and monitor for cap damage. Check whether you have a spare cap at home should you need it in the future.
• If the battery cap contact is damaged, immediately replace it with a spare cap – there may be a spare in the original box that contained your pump. Alternatively, contact the Medtronic Helpline on 01923 205167, choose option 2, then option 0 to request a spare battery cap.
