Medtronic has initiated a recall of some of its insulin pumps after receiving reports that the device was malfunctioning. The Class I recall - the most serious type of recall - includes about 322,000 pumps. The devices affected are the Minimed model 630G ((MMT-1715), all lots before October 2019, and the Minimed model 670G (MMT-1780), all lots before August 2019. According to FDA, "Medtronic is recalling the specified insulin pumps due to a missing or broken retainer ring which helps to lock the insulin cartridge into place in the pump's reservoir compartment. If the cartridge is not locked firmly into place, under or over delivery of insulin may occur, which could result in hypoglycemia or hyperglycemia. Severe hyperglycemia can result in a loss of consciousness, seizure, and death." Medtronic has received 26,421 complaints in which the insulin pumps malfunctioned in this manner. The company is aware of 2,175 related injuries and 1 death. Medtronic first warned of safety problems with the insulin pumps in November.
