Product analysis: as found condition: the solitaire fr stent was returned for analysis within a shipping box; within an unsealed plastic biohazard pouch and within a plastic glove.The solitaire fr pusher was not returned with the stent.Visual inspection/damage location details: the solitaire fr stent was found separated from the pusher at the proximal marker.The solitaire fr stent non-working (tear drop), working length struts, and finger markers were found in good condition.Testing/analysis: the solitaire fr stent was sent out for sem testing.The proximal marker was removed.The stent keyway fingers were found to be intact and still in good condition.The pushwire and ball were not found within the proximal marker.Conclusion: based on the device analysis and reported information, the customer¿s report of ¿pushwire break/separation¿ was confirmed.The solitaire fr stent device appeared to have separated due to a ball slip tensile failure.The solitaire fr pusher was not returned; therefore, analysis could not be performed and conformance to specification could not be assessed.There is an indication that the failure could potentially be related to a manufacturing issue and a dhr review will be performed.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.
