Boston scientific received information that this device was emitting tones.Upon interrogation it was noted that this device recorded a code 1003 indicative of battery voltage too low for the projected remaining capacity.No adverse patient effects were reported.The device was explanted and is not expected to be returned for analysis.Boston scientific has issued an advisory communication regarding an older subset of cognis/teligen devices that is more susceptible to a product performance anomaly.Specifically, the performance of a low voltage capacitor may be compromised over time, causing an increased current drain that can lead to premature battery depletion.This particular device was included in the advisory population.
