Investigation - evaluation: a review of the complaint history, drawings, device history record, documentation, manufacturing instructions, and quality control was conducted during the investigation.The three (3) complaint devices were not returned for investigation.A document-based investigation was performed.There is no evidence to suggest the finished product was not made to specifications.Review of the device history record of the finished product shows no nonconforming events that could contribute to this failure mode.A complaint history search revealed that there were no other reported complaints for this lot number.Based on the information provided and the results of our investigation, the root cause of the leakage can be attributed to the stopcock stems as they are molded of nylon 6 material, which can absorb moisture resulting in an increase in diameter, raising potential for cracking of the stopcock body.Per the quality engineering risk assessment, appropriate measures have been initiated to address this failure mode.Personnel have been notified and monitoring will continue to be performed for similar complaints.
