Investigation summary: a device history review was conducted for lot numbers 8226712 and 8180507.Our records show that this is the only instance of this issue occurring in either connect a batch.According to the sampling plan applied for product performance, each 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.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.
