H3: product analysis #705192005:equipment used: video inspection system (m-81805), ruler (m-83360), camera (panasonic lumix dmc-zs5) drawing(s) referenced: dwgs105-5056 rev.H as found condition: the marathon micro catheter was returned for analysis within a shipping box, within a sealed plastic biohazard pouch; within an opened marathon inner pouch; and within a dispenser coil.An apollo micro catheter was also returned and will be addressed in pli-20 visual inspection/damage location details: the entire surface of the marathon micro catheter was examined under magnification; no pinholes or ruptures were found.Onyx residue was found within the marathon hub.No damages were found with the marathon hub, catheter body or distal tip.Testing/analysis: the marathon total length was measured to be ~173.5cm, the usable length was measured to be ~167.3cm which is within specification (specification: total (ref) = 170cm, usable = 165.0cm ± 2.5cm).The micro catheter was flushed, and water did not exit the distal end as it was found occluded.An in-house 0.010¿ mandrel was inserted into the marathon micro catheter and became stuck within the hub when inserted proximally and at the distal tip when inserted distally.The catheter was cut, and onyx was found within the catheter.The inner diameter of the marathon catheter cannot be measured due to the occlusion.No other anomalies were observed.Conclusion: based on the device analysis and reported information, the customer¿s ¿catheter rupture¿ could not be confirm.The customer¿s report of ¿catheter occlusion¿ was confirmed.It is possible the onyx became exposed to water, saline or blood causing the onyx to solidify and caused the occlusion.This can occur in the hub, catheter lumen, or the needle used to draw the onyx from the vial.Customer reported dead space was filled with dmso, continuous injection was used, and no wait time before injection.Therefore, the cause could not be determined.There is no evidence suggesting that the marathon micro catheter was defective.Ngod10 2022-10-21 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.
