(b)(4).Date sent: 3/26/2020.D4: batch #t93e0x.Investigation summary the device was returned with the blade scratched and cracked.In addition, the blade was not broken off as reported.The device was functionally tested with a generator.During functional testing on gen11 an alert screen was displayed.A probable cause of an alert screen is blade damage.The device will stop activating and display an alert screen when the blade becomes damaged.The manufacturing records were reviewed and the manufacturing/packaging criteria were met prior to the release of this batch.Probable causes of blade damage, including breakage, are external contact during pre-op or general use, blade contact with other devices, staples or clips during the procedure, or using any means other than the blade wrench to attach or detach the blade.Once minor blade damage has occurred, subsequent activations may increase blade damage severity and result in alert screens, such as ¿tighten assembly,¿ ¿blade error detected¿ or "relax pressure on blade," followed by a ¿replace instrument¿ screen later in the procedure.Continued usage can result in a broken blade.
