Additional Manufacturer Narrative
Event related to regulatory report: 2029214-2024-00109 product analysis: as found condition: the axium prime pusher and headway-17 micro catheter were returned for analysis within a shipping box and within a sealed plastic biohazard pouch.The axium prime pusher was broken, and the proximal segment was returned within the headway-17 micro catheter.The distal segment was returned separately.Visual inspection/damage location details: no damages or irregularities were found with the headway-17 hub.The axium prime pusher was found extending out the hub ~5.8cm.The headway-17 catheter body was found kinked at ~150.4cm from the proximal end.The axium prime pusher was found broken distal to the break indicator with the release wire retracted and broken.The proximal segment was not returned for analysis.The pusher was found with a second break at ~134.4cm from the proximal end.The headway-17 inner liner was found on the pusher (figure ).The distal pusher segment was found kinked at ~37.2cm from the proximal end.The coin was found fully retracted out of the lumen stop.The shied coil was found broken.The implant coil was already detached and not returned for analysis.Testing/analysis: the axium prime pusher segment was removed from the headway-17 with resistance encountered.Conclusion: based on the device analysis and reported information, the customer¿s report of ¿coil resistance/stuck in catheter¿ was confirmed.The cause of the resistance was found to be the damaged inner liner becoming entangled with the axium prime pusher.The cause of the inner liner damage could not be determined.The pusher was found kinked and broken, which potentially occurred due to advancing/retracting the device against the reported resistance.The headway-17 has an inner diameter of 0.017¿ and is compatible for use with the axium prime coil.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.
