Investigation results: a sample was received for the purpose of our investigation.The investigators were able to observe the reported failure mode in the sample provided.The batch record was reviewed, no related abnormalities were found.This device was manufactured on the semi-auto line, during the cannula crimp process the cannula & the paddle hub are joined to prevent separation during use.After this point there is a 100% manual inspection of all completed units, mitigating the likely hood of this failure mode being shipped out to the customer.The most likely root cause is the occurrence of an abnormality at the cannula end crimp station and the subsequent and the operators missing it during the inspection process, as the operators are responsible for identifying and removing any nonconforming material.The inspection process was the subject of an improvement project conducted in october, 2017 which culminated in the addition of an inspection station to help reduce the likelihood of failure occurrence.
