Additional Manufacturer Narrative
H3.Product analysis: equipment used: vis m-81805 203cm ruler m-83360.As found condition: the pipeline flex shield braid was returned for analysis within a shipping box; within an opened pipeline flex shield inner pouch; and within a small plastic bio-pouch.There was no puswire returned with the device.Visual inspection/damage location details: the braid was returned already detached from the pusher; therefore, the proximal and distal ends could not be identified.One of the ends of pipeline flex shield braid appeared to be not fully opened and moderately frayed.The other end of the pipeline flex shield braid was found fully opened and moderately frayed.No other anomalies were observed.Testing/analysis: none.Conclusion: based on the analysis findings, the pipeline flex shield could not be confirmed to have failure/incomplete open distal (flex) as the device was resheathed.In addition, the proximal and distal ends could not be identified.It is likely that the patient tortuous anatomy may have contributed to this event.There was no non-conformance to specifications identified that led to the reported issue.H6.Coding updated based on analysis results.Associated with mdr # 2029214-2022-01259.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.
