Additional Manufacturer Narrative
3 opened and 36 unopened knives, in a blisters and some in boxes were received for the report of blunt knives.Three opened samples were visually inspected and found to be nonconforming, blade was observed to have a bent tip for all three samples.Penetration testing could not be performed due to the damage of the sample.Since opened samples were visually nonconforming, a sample plan of 13 randomly unopened knives were selected for visual and functional inspection.The samples were visually inspected and were found to be conforming.The samples were then functionally tested for penetration and were found to be conforming.A review of the device history record traceable to the reported lot numbers, indicates that the reported product was processed and released according to the reported product¿s acceptance criteria.The exact root cause could not be determined from the investigation performed.The damage to the returned samples is consistent with damage that can occur when the blade contacts a hard surface such as the protective blade tray when product is improperly removed or inserted after use, or improper handling, or contact with another instrument during surgery or set-up.The damage seen on the returned complaint samples could have contributed to the customers reported issue of blunt knives.The returned unopened samples were found to be conforming, therefore blunt knives as described in the complaint was not confirmed.The exact root cause for the damaged knife samples is unknown, therefore specific action with regards to this complaint cannot be taken.All knives are 100% inspected by trained operators using a minimum of 10x magnification during manufacturing.Any nonconformance, such as the damaged tip exhibited on the returned opened sample is removed from the lot and scrapped.Functional penetration testing is performed and monitored during the finishing process to ensure the sharpness of the product.Complaints are reviewed and monitored at regular intervals for any significant adverse trends.No adverse trends have been observed associated with the reported product and event.No further actions are required.The manufacturer internal reference number is: (b)(4).
