Medtronic has recalled certain diabetes infusion sets used with its insulin pumps to replace a component that may lead to over-delivery of insulin after an infusion set change. Medtronic recommends that customers use only infusion sets made with the new membrane, available since April, and carefully follow the “Key Steps” document included with the recall notification letter. The company said it will work with patients to ensure that recalled infusion sets are returned and replaced at no cost. Health care providers and patients are encouraged to report adverse events or side effects related to the use of these products to the Food and Drug Administration’s MedWatch program.
