One opened probe was received with a tip protector for the report of actuation failure during surgery.The returned sample was visually inspected and found to be non-conforming with the probe needle bent and foreign material on the needle and in the port.The sample was then functionally tested for actuation, aspiration and cut.The sample was found to be conforming for aspiration and cut and was non-conforming for actuation.The probe was disassembled and the components inspected.No/minimal wear was observed on the inner cutter when compared to the degree of wear based on continuous actuation of the probe visual standard photos.The inner cutter was observed to be bent.No wear marks were observed on the inner cutter.The sample was retested for actuation with the probe driver and was able to actuate.The initial actuation test failed due to an interference within the probe and once the interference (bent needle and shell assembly) was removed the probe was able to actuate.A review of the device history record traceable to the reported lot number indicates that the product was processed and released according to the product¿s acceptance criteria.A complaint history examination for device component lots traceable to the reported lot number indicates there is one additional complaint associated with the component lots for the reported issue.The complaint evaluation confirms that the probe had an actuation failure.The most likely root cause for the actuation non-conformance is the bent needle and bent inner cutter.A damaged/bent inner cutter can impede the movement of the cutter shaft.This interference is present as observed from visual condition of the inner cutter.After the probe was disassembled (bent needle and shell assembly removed), the probe was able to actuate.The exact root cause of the bent needle and bent inner cutter cannot be determined from this evaluation.The most likely root cause is handling at any point after the probe was shipped from the manufacturing site.An exact root cause for the bent needle and the bent inner cutter was not determined from this evaluation; therefore, no specific action with regard to this complaint was taken.Probes are 100% visually inspected and tested for actuation, aspiration, and cut during manufacturing.Any non-conformance's found are removed from the lot and scrapped.Complaints are reviewed and monitored at regular intervals for any significant adverse trends.No additional action is required at this time.The manufacturer internal reference number is: (b)(4).
