Additional Manufacturer Narrative
Product analysis #(b)(4): equipment used: video inspection system (m-78210), ruler 200cm (m-83361).As found condition: the pipeline flex shield embolization device and phenom 27 catheter were returned for analysis within a shipping box; within a plastic bio-pouch; and within an opened pipeline flex inner pouch.The pushwire was returned stuck within phenom 27 catheter.Damage location details: the pusher was extending out from catheter hub.In addition, the distal braid, sleeves and tip coil deployed from catheter distal tip.No bent or kink was found with pusher.The distal hypotube and ptfe shrink tubing were found to be intact with no signs of elongation.No defects were found with the tip coil, distal marker, re-sheathing marker, re-sheathing pad or with the proximal bumper.The distal and proximal dps restraints were found to be intact.The dps sleeves were found intact with no signs of damage.The distal end of the pipeline flex shield braid appeared to be not fully opened due to damaged braid.The proximal end of the pipeline flex shield braid was found fully opened and moderately frayed.No flash or voids molded were observed in the hub.No damage was found with hub.The catheter body was found to be accordioned from ~5.3cm to 3.2cm from distal end.The phenom 27 catheter tip and marker were examined; and no damages were found.No other anomalies were observed.Testing/analysis: for further examination, the pipeline flex shield was pushed out from the catheter without any issues.The total and usable lengths of the catheter were measured to be within specifications.The catheter was flushed with water and water exited out from the distal tip.The catheter was then tested by running an in-house 0.0265¿ mandrel through catheter tip and hub.The mandrel successfully passed through the catheter hub, lumen and tip with no issues; however, the resistance observed at the damaged locations.Conclusion: based on the analysis findings, the pipeline flex shield was confirmed to have failure to open at distal as the distal end of pipeline flex shield appeared to be not fully opened due to damaged braid.However, the cause for damage could not be determined.Possible causes of failure to open includes patient tortuous anatomy and damage to the braid.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.
