Additional Manufacturer Narrative
H3: product analysis visual inspection/damage location details: the introducer sheath was found correctly assembled on the axium device with the wavelock on the proximal end.No damages or irregularities were found with the introducer sheath.The axium implant coil and distal 1.2cm of the pusher were found extending out the distal pusher.The pusher was found kinked at the same location.The axium implant coil was found damaged and stretched with the polypropylene filament unbroken.Testing/analysis: the axium coil was retracted back within the introducer sheath against high resistance.The implant coil tip outer diameter was measured to be 0.0115¿, which is within specification (specification: 0.0112¿ + 0.0010¿ / - 0.002¿).The introducer sheath inner diameter was measured to be 0.0185¿ (0.4699mm), which is within specification (specification: 0.47mm +0.003mm).Conclusion: based on the device analysis and reported information, the customer¿s report of ¿coil resistance/stuck in sheath¿ was confirmed.The distal axium pusher and the implant coil were found damage.There were no reported issues pushing the axium implant coil from within the introducer sheath during hydration per ifu.Therefore, it is possible the implant coil became damaged when retracting the implant coil following hydration or due to improper hubbing technique (over tightening of the rhv/sheath not fully seated within the hub) subsequently causing the implant coil to become stuck.Advancing the coil against resistance would result in damage to the implant and pusher.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.
