Notification of a subset of Medtronic LINQ II™ ICM Systems (LNQ22) with potential issue for amplified noise and/or overall signal reduction

A Dear Healthcare Professional Letter has been issued by Medtronic International Limited to notify healthcare professionals about a population of LINQ II^TM insertable cardiac monitors (ICM) which underwent a manufacturing process that may allow for moisture to impact electrode performance. This may create the potential for amplified noise and/or overall signal reduction of the ICM, which may interfere with intended recordings of heart rhythms. As of 25 August 2023, there have been no reports of serious harm due to this issue. This notification provides instructions on the recall of the unused affected devices and patient management recommendations for existing users of the affected devices. Please refer to the letter for details.
