Additional information provided in d.9., h.3., h.6.And h.11.No technical inquiries were received from the customer.Four unopened probes, with tip protectors, in a pouch were received.Sample 1 was visually inspected and found to be conforming.The sample was then functionally tested for actuation and cut.The sample was found to be conforming for both tests.The probe engine was disassembled, and the components inspected.The diaphragm, spacer, top o-ring are all intact.Sample 2 was visually inspected and found to be conforming.The sample was then functionally tested for actuation and cut.The sample was found to be conforming for both tests.The probe engine was disassembled, and the components inspected.The diaphragm, spacer, top o-ring are all intact.Front housing o-ring inner diameter was damaged.Sample 3 was visually inspected and found to be conforming.The sample was then functionally tested for actuation and cut.The sample was found to be conforming for both tests.The probe engine was disassembled, and the components inspected.The diaphragm, spacer, top o-ring are all intact.Front housing o-ring inner and outer diameter was damaged.Sample 4 was visually inspected and found to be nonconforming with short shot spacer seen through the vent hole and orange/brown foreign material inside the port.The sample was then functionally tested for actuation and cut.The sample was found to be conforming for both tests.The probe engine was disassembled, and the components inspected.The diaphragm, spacer, top o-ring are all intact.Front housing o-ring inner diameter was damaged.A review of the device history record traceable to the lot number obtained from the device¿s radio frequency identification (rfid) tag, indicates that the reported product was processed and released according to the reported product¿s acceptance criteria.The investigation conducted a non-conformance review of the reported lot number.No deviations were identified, and all corresponding production release specifications defined in the device master record were met.Based on the evaluation of the information and materials received, the investigation concluded that the root cause of the reported event is not determined as the returned samples were conforming for all functional testing.However, a manufacturing related potential contributor factor was identified, damaged was observed on the o-ring and short shot spacer and cannot be ruled out for the cut problem as reported.The returned sample functionally met specifications; however, a non-conformance was completed for the damage observed on the o-ring and a non-conformance record was initiated to trend the defect of short shot spacer.A nonconformance investigation was completed to investigate the trend identified for probes with would not cut or actuate issues.All probes are 100% visually inspected and tested for actuation, aspiration, and cut during manufacturing.Complaints are reviewed and monitored at regular intervals for any significant adverse trends.Complaint data for all products is reviewed monthly to monitor for adverse trends.During the last review, adverse trends were observed for the reported product and event combination.Quality assurance has reviewed this complaint and will continue to monitor data for evidence of adverse trending and take further action, as appropriate.No further action warranted at this time.The manufacturer internal reference number is: (b)(4).
