(Fridley MN-) Several types of insulin pumps are being recalled by a Minnesota-based medical device company because of a dangerous flaw that could affect more than 322,000 users with Type 1 diabetes.

The Food and Drug Administration identified the recall of Medtronic's MiniMed 600 Series Insulin Pumps as a "Class I" recall. This is the most serious type of recall and means that use of such products could result in serious injury or death, the Food and Drug Administration says.

Insulin pumps are devices that are designed to deliver exact doses of insulin based on a person's blood sugar levels. The devices in question are being recalled because they may be incorrectly dosing insulin. Delivering too much or too little insulin could result in life-threatening complications in people with Type 1 diabetes.
