Results: bd received samples and photos from the customer facility for investigation.Following evaluations were made: visual/ microscopic evaluation: the septum was molded using the 16 cavity mold.No physical /mechanical damage was observed on any of the external areas of the q-syte unit.Water leak test: the q-syte unit was connected to the water leak test station and tested in the un-actuated and actuated positions.Leakage was confirmed in the actuated position during testing septum column tear assessment: damage (tear) was observed along the column wall.Bottom septum evaluation: the returned unit was disassembled to evaluate the bottom septum condition.No physical/mechanical damage was observed to the septum bottom disk.Photos of the slit centeredness: septum slit cut was not off center on any of the returned q-syte unit.Additionally, bd was unable to determine the specific lot number associated with this complaint.Therefore, a review of the device history record could not be conducted.Conclusion: the defect leakage, as stated as the reported code was confirmed with the returned unit.The root cause of leakage was the vent hole due to the column tear.A definite source that caused damage to the column tear; which contributed to the leakage, could not be established.The failure modes normally attributed to these types of damage are incorrect usage or excessive actuations.
