MAUDE Adverse Event Report: BOSTON SCIENTIFIC CORPORATION INGENIO?; IMPLANTABLE PACEMAKER

Model Number	K173
Medical Device Problem Codes	Premature Discharge of Battery (1057); Battery Problem (2885)
Health Effect - Clinical Code	No Clinical Signs, Symptoms or Conditions (4582)
Date of Event	06/25/2025
Type of Reportable Event	Serious Injury
Event or Problem Description
It was reported that this implantable pacemaker was suspected of premature battery depletion (pbd) as the longevity dropped from 2.5 years to 6 months remaining in a span of 1 year.A request was made to have data from this device analyzed.Data analysis confirmed the battery voltage was previously outperforming the expectations but has now moved closer to expectations.The longevity change is due to the switch from coulometer-based calculation to voltage based.This device remains in service.No adverse patient effects were reported.
Additional Manufacturer Narrative
The product has not been returned for analysis, and it was confirmed the actual rate of battery depletion fell within an acceptable range.Next, a series of diagnostic tests were conducted that verified the performance of pacing, sensing, and recording functions.It was determined that the unexpected change in observed longevity is due to a mismatch between the actual battery voltage and the expected battery voltage per the nominal battery discharge model (which represents how the device's battery voltage typically decreases over time).In some devices, the actual battery voltage remains higher than the nominal model earlier in device life (which results in a higher-than-expected remaining longevity) and then becomes lower than the nominal model later in device life (which results in the remaining longevity appearing to decrease more quickly than expected between routine follow-ups).Boston scientific devices will automatically adjust remaining longevity estimates to maintain the 90-day therapy window between explant and battery capacity depleted.In this case, the battery did not deplete prematurely, rather, the replacement indicator (and associated remaining longevity) was adjusted later in device life to ensure a 90-day replacement period.
