Investigation summary: a device history review was conducted for lot number 8215502.Our records show a trend for this issue has been detected in this batch of bd connecta.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, although our engineers were unable to obtain a device for test, previous investigations and 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 re-occurrence of this event we have retrained our personnel and optimized our manufacturing process to monitor this issue more thoroughly.Bd was not able to duplicate or confirm the failure mode because samples or pictures were not provided, however, since this batch have 12 complaints related to leakage this failure mode could be produced due 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.Conclusion: 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.
