Additional Manufacturer Narrative
H3: product analysis of (b)(4), item:10, lot no:b649183, damage location details: the pushwire was returned extending out from catheter hub.No bent or kink was found with pushwire.However, the distal hypotube was found to be broken.In addition, the distal hypotube was found to be slightly stretched.The distal and proximal dps restraints were found to be intact.The dps sleeves were found intact with no signs of damage.No defects were found with the proximal bumper, re-sheathing pad, re-sheathing marker, distal marker, and tip coil.The distal and proximal ends of pipeline flex shield braid were found fully opened and damaged.No flash or voids molded were observed in the hub.No damage was found with hub.No kink or damages were found with catheter body.The phenom 27 catheter tip and marker were examined; and no damages were found.No other anomalies were observed.Testing/analysis: the total and usable lengths of the catheter were measured to be within specifications.For further examination, the catheter was cut to remove the pipeline flex shield braid from the catheter lumen.The catheter was flushed with water and water exited out from the distal tip.An in-house mandrel was inserted into the phenom 27 micro catheter hub and catheter lumen without issue.The broken end was sent out for sem (scanning electron microscopy) analysis.Conclusion: based on the analysis findings, the pipeline flex shield was confirmed to have pushwire break/separation as the distal hypotube was found to be broken.The broken end failed via fatigue then overload.The review of lot history records shows that the finished device has met all manufacturing requirements and specifications during final assembly and quality inspection.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.Medtronic will submit a supplemental report if additional relevant information becomes known.
