(b)(4) date sent: 4/4/2024 d4 batch #: x94v24 additional information was requested and the following was obtained: did the generator display any error messages and if so what were they? the instrument broken from the handle side.Did the device pass the pre-test? yes had the device been working and then stopped? no , its broken from the handle end did the patient experience any adverse consequences due to this issue? unknown investigation summary the product was returned for evaluation.Visual inspection and functional testing were conducted on the returned device.Visual analysis of the returned sample determined that the device was returned with the handle broken and the piece was returned.In addition, the device was returned with the blade tip damaged, however, the blade was not cracked.The device was connected to a test handpiece and tested on a gen11. the device was analyzed, and it was determined that it was possibly used in more than one procedure, based on generator data.The device is intended and labeled for single patient use.If the device is connected to multiple generators, an alert screen will be displayed indicating ¿adaptive tissue technology features are not available in this device¿. the device was disassembled to verify the internal components and no anomalies were noted. due to the multiple generator usage, which is evidence of possible reuse, we are unable to determine how this condition impacted the performance of the device and, therefore, cannot conclude the root cause.If the device is activated across a clip, staple line, or other metal in the jaws, the blade could get damaged, subsequent activations may increase the severity of the blade damage.Once minor blade damage has occurred can result in activation issues such as failing the pre-run test with the generator and displaying an alert screen.These alert screens that can result are such as ¿tighten assembly¿, ¿blade error detected¿ or "relaxed pressure on blade" followed by a ¿replace instrument¿ screen later in the procedure.Continued usage of the damaged blade can result in a broken blade.As part of the quality process, all devices are manufactured, inspected, and released to approved specifications. a manufacturing record evaluation was performed for the finished device batch x94v24, and no non-conformances were identified.
