Manufacturer Narrative
This is a report for a similar device that is not marketed in the us.Suspect medical device - similar device brand name = pipeline flex w/shield technology model # = ped2-400-35 the pipeline flex with shield device has not been returned for evaluation; product analysis cannot be performed.The device was not returned, therefore the reported event could not be confirmed.The cause of the event cannot be conclusively determined from the provided information.If information is provided in the future, a supplemental report will be issued.
 
Event Description
Medtronic received report that the pipeline flex with shield device pushwire broke.The patient underwent embolization treatment of a giant unruptured, saccular left internal carotid artery (ica) pre-ophthalmic, aneurysm.The max diameter was 23mm and the neck diameter was 12mm.The distal landing zone was 18mm and the proximal was 23mm.The vessel was observed moderately tortuous.It was reported that after releasing the device, it was not possible to recapture the pipeline delivery wire, because the micro-catheter was outside the wire.The pushwire broke and broken segment was at left ica against wall, a second pipeline was placed to trap the broken segment.Post the intervention, there was good result with two telescoped pipelines.There were no reports of patient injury in association with this event.
 
Manufacturer Narrative
The pipeline flex with shield pushwire was returned without the catheter.The pushwire appeared to be intact.No separation was found with returned pushwire.The distal and proximal dps restraints were found to be intact.The dps sleeves were found intact with no signs of damage.The outer diameter (o.D) of the re-sheathing pad was measured within specifications.The distal hypotube and ptfe shrink tubing were found to be intact with no signs of elongation.No damages were found with the tip coil, distal marker, re-sheathing marker or with the proximal bumper.No other anomalies were observed.Based on the analysis findings, the pipeline flex with shield was not confirmed to have pushwire separation and resistance during delivery as the returned pushwire was found to be intact.No separation was found with the pusher.In addition, no damages were found with the pushwire.It is possible that the patient tortuous anatomy may have contributed to the resistance during delivery.There was no non-conformance to specifications identified that led to the reported issue.Since the pipeline flex shield braid and catheter were not returned; any contribution of the braid and catheter to the issues could not be determined.Per our instructions for use (ifu): "begin to deliver the device using a combination of unsheathing the pipeline flex embolization device and pushing delivery wire simultaneously.After the distal end of the pipeline flex has successfully expanded, deploy the remainder of the device.Carefully inspect the deployed pipeline flex embolization device under fluoroscopy to confirm that it is completely apposed to the vessel wall and not kinked.If the device is not fully apposed or is kinked, consider using a balloon catheter, micro catheter, or guide-wire to fully open it.The system is designed to allow for 2 full cycles of re-sheathing of the pipeline flex embolization device.Re-sheathing the pipeline flex embolization device more than 2 full cycles may cause damage to the distal or proximal ends of the braid.Do not use in patients in whom the angiography demonstrates the anatomy is not appropriate for endovascular treatment, due to conditions such as severe intracranial vessel tortuosity or stenosis.¿ 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.
