- Mar 30, 2026Class IIOpen, Classified
For some patients upgraded from a LUX-Dx M301 device to a new Model M302 or M312, the new ICM device is not collecting PVC Burden data (both M302/M312) or monitoring for Bradyarrhythmia and Pause (M312 only). In addition, for these devices that are not being monitored, the LATITUDE Clarity programming screens have discrepant information, indicating that the monitoring is enabled for these features in one location and not enabled in another location.

MAUDE report 50890393 ↗InjurySep 24, 2026Premature Discharge of Battery
It was reported that this Insertable Cardiac Monitor (ICM) was explanted for battery replacement. No additional adverse patient effects were reported.
Patient problems: No Clinical Signs, Symptoms or Conditions
MAUDE report 50889972 ↗MalfunctionSep 24, 2026Premature Discharge of Battery
It was reported that this Insertable Cardiac Monitor (ICM) device was interrogated and showed End of Service. Technical Services recommended device replacement and requested the device be returned for analysis. Additional information indicated that the patient had been wearing a magnet over the implant area since the time of implant. The potential effects were discussed; patient education and physician notification were recommended. No adverse patient effects were reported. This ICM remains in service.
Patient problems: No Clinical Signs, Symptoms or Conditions
MAUDE report 50885288 ↗MalfunctionSep 22, 2026Premature Discharge of Battery
It was reported that this Insertable Cardiac Monitor reached the Recommended Replacement Time earlier than expected. Engineering analysis found evidence of excessive magnet use, which increased power consumption and most likely caused premature battery depletion. The findings were communicated to the field representative. No adverse patient effects were reported. This product remains in service.
Patient problems: No Clinical Signs, Symptoms or Conditions
MAUDE report 50856105 ↗MalfunctionSep 11, 2026Premature Discharge of Battery
It was reported that an Insertable Cardiac Monitor (ICM) indicated an EOS (End of Service) condition during preparation for implant. The Insertable Cardiac Monitor had been enrolled but was not implanted, and an alternate Insertable Cardiac Monitor was used instead. Technical Services requested return of the affected Insertable Cardiac Monitor for evaluation; however, the hospital retained and subsequently discarded the Insertable Cardiac Monitor, making product analysis unavailable. The representative later confirmed that the Insertable Cardiac Monitor successfully transmitted a remote report prior to disposal. No patient impact occurred because the Insertable Cardiac Monitor was not implanted. No adverse patient effects were reported.
Patient problems: No Clinical Signs, Symptoms or Conditions
MAUDE report 50733404 ↗MalfunctionSep 11, 2026Premature Discharge of Battery
It was reported that the Insertable Cardiac Monitor (ICM) experienced a sudden drop in battery voltage resulting in an end of service condition. Technical assessment determined that the battery voltage decline occurred unexpectedly and the cause of the depletion is unknown. No patient impact was reported. The ICM remains in service.
Patient problems: No Clinical Signs, Symptoms or Conditions
MAUDE report 50733078 ↗MalfunctionSep 9, 2026Premature Discharge of Battery
Patient problems: No Clinical Signs, Symptoms or Conditions
MAUDE report 50699816 ↗InjurySep 4, 2026Failure to Read Input Signal; Device Sensing Problem
It was reported that this newly implanted Insertable Cardiac Monitor (ICM) device initially functioned as expected. After the procedure was completed and the incision was closed the transmitted signal became indiscernible despite confirmation of proper ICM device placement via X-Ray. Troubleshooting efforts did not restore adequate sensing; therefore, the ICM was explanted and replaced. The new ICM showed normal signal quality, and the explanted ICM was returned for analysis. No additional adverse patient effects were reported.
Patient problems: No Clinical Signs, Symptoms or Conditions
