Manufacturer Narrative

Additional information: b5 & d10 involved components updated.D9 - product return date.Investigation: visual investigation: here we detected misaligned jaws.Furthermore, products have been forwarded to the responsible production department for further analysis.Pl536r were received, and one was not within specification due to misaligned jaw, not acceptable cartridge retention force and td *03/*04 are outside our allowable tolerance.Batch history review: due to the fact that no lot number was provided, a review of the device history records (dhr) for the complained device is not possible.The review of risk assessment revealed that the overall risk level ((3)5 severity x probability of occurrence 1(5)) according to din en iso 14971 is still acceptable.Explanation and rationale: unfortunately, due to a lack of data a review of the dhr history record is not possible.Investigation leads to the assumption that the cause for the mentioned deviation was caused by an improper handling.If the product was tilted in the basket during reprocessing, there is the possibility that the jaws misaligned, and a further clip feeding is no longer possible.Furthermore, if the cartridge is engaged not completely or was damaged during inserting, there is an impairment of product functionality.This could lead to deformed latches of the slider sheet, to clip jam and can cause the cartridge to jump off.Based upon historically grown product experience and due to different simulation regarding a cartridge which is engaged not completely, this leads to the described errors.Conclusion and measures /preventive measures: based upon the investigation results, the root cause of the problem cannot clearly be determined.There is no indication for a material or design-related failure.Based upon the investigation results, a capa is not necessary.
