Additional Manufacturer Narrative
H3.Evaluation summary: medtronic conducted an investigation based upon all information received.The device was available for evaluation.Visual inspection noted that the reload was partially fired and the interlock was engaged.The sled and staples were visible and the jaw of the reload was open.Staple pushers were also visible and the proximal sutures were cut properly.The distal suture at end of the cartridge side were returned intact.Suture at distal end of the anvil side was disengaged.The buttress materials were dislodged from the reload sutures.Staple pushers on the proximal side were pushed back to the cartridge.There were deformed anti-friction nylon pads on i-beam.Damage to the cutting edge of the knife blade was observed.Functionally, the reload was loaded into a representative handle.The clamping mechanism was deformed.The interlock was overridden and the reload was applied to test media.All remaining staples were placed, and test media was transected.The reload interlock was tested and found to function properly.It was reported that the instrument material did not release.The reported issue was confirmed.The product analysis noted evidence that the device was not used as intended.This issue may occur when firing over tissue that is beyond the recommended thickness range.The manufacturing records for each device are thoroughly reviewed prior to release to ensure that it meets all medtronic quality specifications.The instructions included with this device provide the following guidance: failure to completely fire the reload will result in an incomplete cut and/or incomplete staple formation, which may result in poor hemostasis and/or leakage.Always inspect the tissue thickness and select an appropriate staple size prior to application of the device.Overly thick or thin tissue may result in unacceptable staple formation.When positioning the stapler on the application site, ensure that no obstructions, such as clips, are incorporated into the instrument jaws.Firing over an obstruction may result in incomplete cutting action and/or improperly formed staples.Medtronic submits this report to comply with fda regulations 21 cfr parts 4 and 803.Medtronic has made reasonable efforts to provide as much relevant information as is available to the company as of the submission date of this report.This report does not constitute an admission or a conclusion by fda, medtronic, or its employees that the device, medtronic, or its employee caused or contributed to the event described in the report.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.Medtronic will submit a supplemental report if additional relevant information becomes known.

Event or Problem Description
According to the reporter, during a thoracoscopic right lung lobectomy, the surgeon tried to release the reinforcement material from the tissue by firing into the lung parenchyma, but the reinforcement material did not separate from the tissue, and it started to tear it off.The release status could not be confirmed under a thorascope.No intervention was performed.There was no patient injury.Medtronic's initial evaluation of the returned product found that the reload was partially fired and the interlock was engaged.
