The event unit was returned to applied medical for evaluation.Upon inspection, engineering confirmed that the lip of the bottle was damaged and the outer walls of the scope warmer bottle had collapsed.Based on the condition of the returned unit, it is likely that the outer walls of the scope warmer bottle had collapsed during the sterilization process due to pinholes in the scope warmer bottle.The pinholes were likely caused by repeated usage of the scope warmer bottle over time.The probability and criticality of harm resulting from this failure have been evaluated and were found to be at an acceptable level.
