Event or Problem Description
Medtronic received a report of pipeline flex failure to open.The patient was undergoing pipeline flex embolization treatment for a medium unruptured saccular aneurysm located in left internal carotid artery.Measuring 14mm x 8mm, landing zone distal 4.2mm proximal 5.1mm.The vessel was observed moderately tortuous.The devices were prepared as indicated in the ifu.A continuous flush was used during the procedure.It was reported that during the procedure, the pipeline flex was unsheathed and was unable to open on the distal end.Less than 50% the pipeline had been deployed when it failed to open.The pipeline resheathed and removed with the microcatheter.The procedure was completed by placing a new device.There were no reports of patient injury in association with this event.
Additional Manufacturer Narrative
H3: the pipeline flex was returned within the inner pouch; inside of a sealed bio-hazard bag and a shipping box.When compared to the drawings 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 pipeline flex braid were fully opened and no damage.No bend was observed on the pusher.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 was not confirmed to have failure to open at the distal end as the returned pipeline flex braid was fully opened and no damage.It is possible that the patient tortuous anatomy may have contributed to the failure to open issue.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.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.
