Additional Manufacturer Narrative
Product analysis: as found condition- the axium prime device was returned for analysis within a shipping box, within a resealable plastic pouch and within an opened axium prime inner pouch.Visual inspection/damage location details: the actuator interface was found fully retracted out of the coupler tube with the release wire broken from the actuator interface.The actuator interface was not returned for analysis.The break indicator was found unbroken.No evidence of manual detachment attempts was found at this location.Axium prime pusher was found kinked at ~112.5cm from the proximal end.The coin was found still against the lumen stop.Blood was found under the ptfe shrink tubing and within the lumen stop.The implant coil was found still attached to the pusher.The implant coil was found to be stretched with the polypropylene filament unbroken.Testing/analysis ¿ the break indicator was broken, and release wire was retracted; however, the coin did not exit the lumen stop as the release wire was found stuck.Under magnification, the ptfe shrink tubing was removed, and the blood was dissolved.The release wire was retracted, and the coin exited the lumen stop with no issues and no resistance encountered.No other damages or anomalies were found with the returned device.Conclusion - based on the customer report and device analysis, the customer report of "non-detachment" was confirmed.It is likely the cause of the non-detachment is the blood found within the lumen stop and under the jacket caused the coin to become stuck within the lumen stop.The pusher was found kinked, which could potentially contribute towards the stuck release wire.The implant coil was found stretched.Possible causes include, but not limited to, lack of hydration before procedure, continuous flush not performed during procedure (or insufficient continuous flush), tortuous anatomy, coil is not retracted in a one-to-one motion with the implant pusher during repositioning, pushwire rotation, user advances/retracts the coil against resistance, incompatible catheter, or damage during return shipping to medtronic.The actuator interface and instant detacher used in the event was not returned.Therefore, any contribution of the actuator interface and instant detacher towards the non-detachment could not be determined.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.
