(b)(4).Batch # p5887g.Device analysis: the analysis results found that the ntlc75 device was received with the firing mechanism damaged as the firing knob was detached and the slip block assembly was noted to be damaged.The device was received with one reload present.The reload was returned with the knife exposed, with the proximal 62 drivers up without staples and the remaining drivers down with staples present; the swing tab in the locked position.The damage to the firing knob and slip block assembly is consistent with high (outside indicated use) staple forming forces; however there is insufficient evidence to determine the cause of the higher loads.It should be noted that the cartridge reload is designed to lockout, as a safety feature, if any staples have been fired from the cartridge reload.If enough force is applied the device could be damaged.For additional information please refer to the instructions for use.No functional test could be performed with it due to the condition of the device.The batch history record was reviewed and no defects, ncr¿s or protocols related to the complaint, were found during the manufacturing process.Additional information was requested and the following was obtained: when the firing knob was detached from the device, did it fall into the patient? if yes, was it removed? will it be returned with the device for analysis? if not, was it disposed of? the detached firing knob was collected.And, it will then be returned for analysis.
