Pump Issues – Medtronic and Animas.

Just in case you didn’t know, or in case you’ve moved your e-mail or physical address and you didn’t get these, here are a couple of important notices from insulin pump makers Metronic and Animas.

– First, the Med-T notice, regarding possible loose drive support caps. The drive support cap holds the pump’s motor in place. If you have a Paradigm insulin pump, check the little disc portion on the bottom, just to the right of your light button– your down arrow. That’s the drive support cap. If that disc seems to be pushing out from the pump housing, Medtronic wants you to call them and arrange to send your pump back. Don’t worry, they’ll send you a new one.

Most important: Do not push on the drive support cap! There was an instance of someone pushing on the drive support cap, causing extra insulin to be delivered, which in turn caused severe hypoglycemia. By the way, I checked the drive support cap on my own Revel™ pump and everything is okay. Whew.

If your drive support cap is pushing out, call Medtronic customer support at 1-888-204-7616 and choose option 1. They’ll work with you to send the pump back so you can get a new one. In the notice I received, there was an additional note about making sure you don’t get your pump wet. But if you’ve had your Medtronic pump for any time at all, you already know you shouldn’t take it for a swim or put it in the wash or drop it in the toilet. Not that anyone would want to do that last thing, but you get where I’m going with this, yes?

Second, an all-out recall of certain Animas pumps. From the U.S. Food and Drug Administration:

Animas identified a component issue affecting Animas 2020 Infusion Insulin Pumps manufactured from March 1, 2012 to November 30, 2012. The component issue may trigger the pumps to sound a false alarm or warning related to one of the following:

“Loss of prime”
“No Cartridge detected”

If you receive any of these alarms, the pump may prompt you to complete the rewind, load and prime sequence to clear this alarm. Failure to follow the pump’s safety instructions and disconnect your infusion set from your body before the “rewind, load and prime” steps can lead to unintended delivery of insulin, placing you in danger of potential serious health risks, such as hypoglycemia.

The Animas 2020 Insulin Pump also has a software limitation that will impact the ability of the pump to function past December 31, 2015. After this date, the pump will no longer deliver insulin and will generate a “Call Service Alarm.”

If this describes you and your pump, you should call the Animas Product Fulfillment Center at 877-280-2339 between the hours of 6 a.m. and 12 a.m. EDT so they can work out the details of shipping your free replacement pump. If you have technical questions, or if you want to report a concern, you should contact the Animas Customer Technical Support Center at 866-793-5253. For the full notice from the FDA, go to:

For many of us, these are our lifelines. Be safe everyone. If you have a Metronic or Animas pump, check your pump now, and if you need to, do something about it… now.
