Medtronic (NYSE:MDT) is warning patients who use its MiniMed 600 series insulin pumps of an issue that could cause a dangerous over- or under-dosing of insulin.
In a letter to patients, the company said that the pump’s insulin reservoir may become loose if a retainer ring breaks, preventing a proper lock. Dropping the pump or bumping it on a hard surface may break that ring, the company said. If the reservoir is not properly locked into the pump, it could lead to over- or under-delivery of insulin, which could then result in hypoglycemia or hyperglycemia. The recall covers MiniMed 630G (model MMT-1715) and MiniMed 670G (model MMT-1780).
