Additional Manufacturer Narrative
H3: product analysis of ped2-475-30, lotno:b554109, visual inspection/damage location details: the distal and proximal dps restraints were found to be intact.The dps sleeves were found intact with no signs of damage.The distal hypotube and ptfe shrink tubing were found to be intact with no signs of elongation.The distal and proximal ends of the braid were opened and frayed.No bends were found with the pushwire.No defects were found with the tip coil, distal marker, re-sheathing marker, re-sheathing pad, or the proximal bumper.No other anomalies were observed.Conclusion: based on the returned device, the customer complaint was not confirmed as the distal and proximal ends of the braid were fully opened and frayed.Possible causes of ¿failure/incomplete open¿ include vessel tortuosity, damaged braid, or user deploying braid in vessel bend.The customer reported that vessel tortuosity was normal.In addition, the pipeline flex was not deployed in the vessel bend., ruling out vessel tortuosity and deploying in the vessel bend as the potential causes.In the event, the damage to the braid may have contributed to the failure to open.The braid can become damaged due to resheathing more than 2 times, over-manipulation, deployment technique, delivering/retracting delivery wire against resistance, or deploying/resheathing the braid against resistance.However, the cause of the braid damage could not be determined.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.
