Manufacturer Narrative

Evaluation summary: medtronic conducted an investigation based upon all information received.The device was available for evaluation.Visual inspection noted the reload was fully fired, the jaws were open, and the reinforcement material was missing.All sutures were released/cut.When disassembled, it was that found the knife laminates were bent outward.This prevents the lock legs from engaging with the channel adapter, allowing the reload to cycle through interlock.There was damage to the channel adapter where the knife laminates scraped along the adapter during firing.Functionally, the reload was loaded into a representative instrument.The reload was cycled without hesitation or binding and was applied to test media.The test media was cleanly transected.The reload interlock was tested and did not engage.It was reported that the jaws of the device remain closed on tissue and resistance while attempting to retract the knife.The reported issues were confirmed.The most likely cause was determined to be manufacturing related.Bent knife laminates can occur from improper component orientation.The bent knife laminates push the interlock legs down causing the interlock to fail.Internal process improvements have been initiated to mitigate this issue.Medtronic is submitting this report to comply with fda reporting regulations under 21 cfr parts 4 and 803.This report is based upon information obtained by medtronic, which the company may not have been able to fully investigate or verify prior to the date the report was required by the fda.Medtronic has made reasonable efforts to obtain more complete information and has provided 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.In particular, this report does not constitute an admission by anyone that the product described in this report has any ¿defects¿ or has ¿malfunctioned¿.These words are included in the fda 3500a form and are fixed items for selection created by the fda to categorize the type of event solely for the purpose of regulatory reporting.Medtronic objects to the use of these words and others like them because of the lack of definition and the connotations implied by these terms.This statement should be included with any information or report disclosed to the public under the freedom of information act.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.A good faith effort will be made to obtain the applicable information relevant to the report.If information is provided in the future, a supplemental report will be issued.
