(b)(4).Date sent: 7/10/2025.D4 batch #: c9e24w.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 blade tip damaged, however, the blade was not cracked.In addition the pad was returned melted not all present the device was connected to a test hand piece 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¿.No unexpected ready to pre-run test issue was observed at any time as reported.The device was disassembled to verify the condition of 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 root cause.If the device is activated across a clip, staple line or other metal in the jaws, it is possible that the generator will display an alert screen, and after receiving two consecutive alerts screens a "replace instrument" alert screen will be displayed by the generator.Once minor blade damage has occurred, subsequent activations may increase the severity of the blade damage.This in turn can result 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 damage blade can result in a broken blade.Probable causes of tissue pad damage are applying pressure between the instrument blade and tissue pad without having tissue between them.Avoid activating the blade without tissue between the blade and tissue pad to prevent damage to the tissue pad.Keep the clamp arm open when back cutting or while the blade is active without tissue between the blade and tissue pad to avoid damage to the tissue pad.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 lot/batch c9e24w, and no non-conformances were identified.This report is being submitted pursuant to the provisions of 21 cfr, part 803.This report may be based on information which has not been investigated or verified prior to the required reporting date.This report does not reflect a conclusion by ethicon, or its employees that the report constitutes an admission that the product, ethicon, or its employees caused or contributed to the potential event described in this report.If information is obtained that was not available for the initial report, a follow-up report will be filed as appropriate.
