H3: product analysis as found condition (condition of returned device): the axium prime device and echelon-10 microcatheter were both returned for analysis within a shipping box, wrapped in plastic, and contained within an opened axium prime outer carton and an opened axium prime inner pouch.The axium prime implant coil was within an introducer sheath.Damage location details: the introducer sheath was found to be in good condition.The pushwire was found bent at ~4.2cm from the proximal end.In addition, the pushwire was found to be bent within the introducer sheath at ~12.8cm from the distal end.The axium prime implant coil was found to be damaged within the introducer sheath.The implant coil polypropylene filament was found to be attached to the detachable element.The axium prime implant coil failed to advance outside of the introducer sheath.Testing/analysis (including sem reports): the axium prime implant coil could not be tested in-house due to its damaged condition.Conclusion: based on the device analysis and the reported information, the customer¿s report of ¿coil resistance/stuck in cath.Hub¿ was able to be confirmed.The axium prime implant coil was returned stretched, damaged, and with the pushwire bent.Advancing the coil against resistance could lead to possible damage; therefore, it is possible that the implant coil was damaged while the user advanced the coil against the reported hub resistance.The customer noted that ¿during the procedure, the axium prime was stuck in the hub of the echelon 10 ¿, which could be a possible cause for the damage.The axium prime device was found to be compatible with the echelon-10 microcatheter.Possible causes for failure are, but not limited to, damage to the coil due to excessive tightening of rhv, sheath not properly seated in hub, and catheter hub transition.The cause could not be determined.Medtronic submits this report to comply with fda regulations 21 cfr parts 4 and 803.Medtronic has made reasonable efforts to provide 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.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.Medtronic will submit a supplemental report if additional relevant information becomes known.
