Additional Manufacturer Narrative
(b)(4).Date sent: 4/28/2026 d4 batch #: z70255 h10: 5201770000-2026-8005 the following information was requested, but unavailable: did the patient experience any adverse consequences due to this issue? 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 broken inside of the tube.The blade tip was returned.During functional testing to the energy systems, an alert screen was displayed.The device will stop activating when the blade becomes damaged.The device was disassembled to inspect, the broken blade was located at an area inside the tube proximal to the tissue pad.This is consistent with a side load being applied to the blade while active with the jaw closed.A manufacturing record evaluation was performed for the finished device lot/batch number, and no non-conformances were identified.Once minor blade damage has occurred, subsequent activations may increase the severity of the blade damage.This in turn 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 "remove instrument from patient" or ¿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.No conclusion could be reached as to how the blade crack issue occurred.As part of the quality process, all devices are manufactured, inspected, and released to approved specifications.
Event or Problem Description
