MAUDE Adverse Event Report: BOSTON SCIENTIFIC CORPORATION ALTRUA 60; IMPLANTABLE PULSE GENERATOR, PACEMAKER (NON-CRT)

Model Number	S603
Medical Device Problem Code	Battery Problem (2885)
Health Effect - Clinical Code	No Clinical Signs, Symptoms or Conditions (4582)
Date of Event	12/03/2021
Type of Reportable Event	Serious Injury
Event or Problem Description
It was reported that this device showed half a year remaining from two months ago with magnet rate of ninety.Recently, device battery was at one year remaining with the same magnet rate.Boston scientific technical services (ts) discussed battery performance would vary a lot in this device in which it could be that the low estimate was right after a telemetry session that took longer or lead testing.Ts then advised to save to disk for analysis.To date, the device remains in service.No adverse patient effects reported.
Additional Manufacturer Narrative
This product has not been returned to boston scientific, and as a result, laboratory analysis could not be conducted.The associated investigation determined that battery status indicators were different than expected based on information provided to boston scientific.Factors influencing the estimated longevity remaining calculation include pacing rate, amplitude, pulse-width and lead impedance.Any even slight changes in these factors will impact the battery consumption calculation and therefore the remaining longevity estimate.Please refer to the description for more information regarding the specific circumstances of this event.Please note this pacemaker's battery was designed to estimate remaining longevity and trigger corresponding device replacement indicators based on the pacing capacitor charge time, which progressively increases as the battery depletes.These pacemakers were not designed with an ability to calculate remaining longevity for every possible current drain, which may cause replacement indicators to trigger earlier than what was previously estimated; however, it does not negatively impact the use, operation, safety, or performance of the device.
