Investigation summary: a device history review was conducted for lot number 8180508.Our records show that this is the only instance of leakage occurring in this production batch.According to the sampling plan applied for product performance, this lot was accepted and released without defects being noted during the final assembly or visual inspections.Additionally, our engineers were able to duplicate this event through the leakage testing of the submitted device.A subsequent review of our manufacturing line determined that the most likely root cause for this event is an abnormality in the equipment responsible for tubing assembly.To prevent a reoccurrence of this event we have retrained our personnel and optimized our manufacturing process to monitor this issue more thoroughly.Bd was able to confirm the customer¿s indicated failure mode because one of the received samples shown leakage.Customer reported injection valve leakage; this failure mode was detected in others customer complaints where leakage occurred at the valve port assy.Due to a bad tubing assembly.Engineering team assessed the assembly process finding a worn pin in station 5 that could cause the reported failure mode.This pin is in charge of assembling the gray tubing into the valve housing.Process fmea rm5943 and process eura eurap2053001 were reviewed and there are proper controls in place to detect product malfunctions.Based on investigation results to date, for leakage issue (in injection valve) root cause was associated to a bad tubing assembly by station 5 of equipment vh59, however, nogales site opened capa to perform an investigation.
