Manufacturer Narrative

Product analysis: as found condition: the solitaire x pusher was returned for analysis within a shipping box, an opened solitaire x outer carton (b491025), and a plastic bio-pouch.Damage location details: no bends or kinks were found with the solitaire x pusher.The stent was found to be separated from the pusher at the distal edge of the marker coil.The separated stent was not returned.The pusher outer shrink tubing and marker coil outer coils were removed.The pusher inner wire was found to be separated at ~3.0cm from the proximal end of the marker coil.Testing/analysis: the separated inner wire was sent out for sem failure analysis.Per the sem report, the broken end failed via ductile overload.Conclusion: based on the device analysis and reported information, the customer¿s ¿separation¿ report was confirmed.Possible causes of device separation can occur due to vessel tortuosity, delivery/retrieval friction, a higher number of device passes, guide/balloon catheters or intermediate catheter integrity issues such as kinking within the shaft, presence of a pre-existing extra/intracranial stenosis or calcified plaque, presence of hard clots/thrombus entanglement with overbending during the retraction process, not aligning the microcatheter with the proximal end of the solitaire device, or removal of the microcatheter prior to retrieval of the solitaire device with or without clot.However, the cause of the device separation could not be determined due to insufficient information.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.
