Medtronic received information that this coil would not detach with an instant detacher or using manual detachment method (breaking hypotube method; an alternative method presented in the instruction for use).The patient underwent embolization treatment for asmall ruptured saccular aneurysm located in left middle anterior communicating artery aneurysm, measuring 6.5mmx2.2mm.The vessel was normal tortuous.It was reported that the physician took apb-6-10-3d-ss as first coil and deployed completely in the aneurysm.But when he tried to detach it, it was not getting detached.The physician attempted two times with one instant detacher, one time with second detacher and one time tried manual detachment to detach the coil, but coil did not detach.So, had to take out this coil <(>&<)> took other coils to finish the procedure.Used the same instant detacher to detach other coils also <(>&<)> it worked properly.There were not any patient symptoms or complications associated with this event.No images are available for review.No patient injury was reported.Reported device and any accessory devices were prepared as indicated in the ifu.

The pusher was returned inside of its outer carton and a shipping box.There was no implant coil, instant detachers, micro catheter, or accessories returned with the pusher.The ai and coupler tube were present but loose; indicative of mechanical detachment was attempted.The pusher appeared to be broken and separated at the break indicator with the release wire extending out from the proximal end; it appeared that manual detachment attempted at this location.Kinks and bends found along the length of the pusher at 10.0cm to 138.5cm from the proximal end.The coin appeared to be pulled back from the lumen stop; with the shield coil was present and intact.The implant coil already detached and not returned.The inner diameter of the lumen stop and the inner diameter of the retainer ring were found to be visually acceptable and no damage.The lumen stop inner diameter (id) was measured to be 0.00270¿ and found to be within specificatio.(0.00220" minimum - 0.0029" maximum).The retainer ring inner diameter (id) was measured to be 0.00458¿ and found to be within specification (0.00455"+/- 0.00010").All other subassemblies appeared to be normal.No other anomalies were observed.Based on the analysis performed, the axium prime coil was not confirmed to have non-detachment as the pusher was returned with the implant coil already detached.There was evidence of mechanical and ma nual detachment attempts to detach the coil.In addition, the pusher was bent and kinked along its length, indicative of high tortuosity.Based on the returned device, there was no malfunction of the pusher or non-conformance to specification identified that led to the non-detachment.Since the implant coil, instant detachers and catheter were not returned; any contribution of the implant coil, instant detachers and catheter to 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.
