(b)(4).Batch # p93x98.Investigation summary: the device was returned with the clamp arm detached from the inner tube, but firmly fixed to the outer tube at the clamp arm weld.The tissue pad was found in good physical condition and properly attached to the clamp arm.The device was connected to a test hand piece and a gen11 and the device did activate during functional testing.Due to the returned condition of the device, not all functional testing could be performed with the generator.The device was disassembled to inspect the internal components and no anomalies were found.Possible causes for the clamp arm detachment may include not closing the clamp when sliding the torque wrench on and off, not closing the clamp when introducing or removing through the trocar, or possible entanglement in fibrous tissue.The batch history record was reviewed and there were no defects, protocols or ncr(s) found during the manufacturing process related to this complaint.
