Results: one sample unit from an unknown lot number was received for evaluation by our quality engineer team.Upon examination, the septum top disk was observed to be completely torn from the rim of the top body.Further analysis of the sample revealed evidence of residual septum material and adhesive deposits; an indication that a bond was provided during the manufacturing process.As no evidence was found to support manufacturing related issues for the reported defect, a root cause could not be determined.A review of the device history record could not be performed as no lot number was provided for this incident.The septum top disk was completely torn from the rim of the top body and the bottom portion of the septum.Residual septum material and adhesive deposits were observed on the rim of the top body.Investigation samples meet manufacturing specifications: no, the returned unit provided for evaluation displayed the septum top disk was completely torn from the rim of the top body and the bottom portion of the septum.Conclusions: the defect septum damaged/defective, as stated as the reported code was confirmed with the returned unit.Conclusion: the root cause is indeterminate.The evaluation of the septum/top body damage location revealed evidence of residual septum material and adhesive deposits.This is an indication that a bond was provided during the manufacturing process.
