A device history review was conducted for lot number 7327618.
Our records show the reported lot was manufactured on 12/04/2017; it was determined that this is the third instance of a needle retraction failure 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.
A sample could not be obtained for evaluation and testing.
Without the ability to investigate the affected unit our quality engineers were unable to determine the root cause for this complaint.
Bd was able to duplicate the customer¿s indicated failure mode performing an incorrect activation from safety device, if user after having done correctly the insertion, upon pulling back on safety device it is performed since adapter clear prn and puller sti, removing all safety device and leaving exposed cannula.
Currently, there is a sampling plan in place lot by lot to look for this kind of defect and according to internal process rejects (qn¿s) database, no issues like this have been reported.
Dhr review for lot reported of catalog 383323, all samples taken for visual and functional characteristics properly met the acceptance criteria.
We will keep monitoring the manufacturing process and in case any emerging trend is detected, further actions will be taken if necessary.
Pfmea¿s 4797 and p-eura rm5942 was reviewed and process controls are very likely to detect failure modes and prevent failures end users.
