Manufacturer Narrative

The product is being evaluated in our post market quality assurance laboratory.This report will be updated when evaluation is complete.(b)(4).

Event Description

It was reported that remote monitoring identified this device was in safety mode.The device reverted to unipolar pacing which resulted in oversensing and pacing inhibition.Additionally, elevated threshold measurements and muscle stimulation were noted.The device was explanted and replaced.No additional adverse patient effects were reported.

Event Description

Manufacturer Narrative

Upon receipt at our post market quality assurance laboratory, this device was thoroughly inspected and analyzed.Interrogation of the device confirmed it was operating in safety mode due to system resets.It was confirmed that brady therapy remained available.The system resets occurred while communicating with the latitude remote monitoring system and caused the device to enter safety mode.Engineers determined that this device was demonstrating behavior consistent with a high internal cell impedance within the battery.The high internal impedance resulted in the system resets due to temporary high-power consumption related to telemetry attempts and subsequent reversion to safety mode operation.Boston scientific has issued a field safety notice regarding ingenio extended life (el) and cardiac resynchronization therapy pacemaker (crt-p) devices that may exhibit this behavior.This particular device is included in the high impedance in ingenio extended life (el) pacemaker and crt-p advisory population.As no further information concerning this report is expected, our investigation is complete.This investigation will be updated should further information be provided.
