Manufacturer Narrative

Additional information: no intervention was required as a result of the event product analysis: one photo received from the account of sterile pouch label of an onyxng27522ux, lot number 0011250740 which matches what is on file from the account.The words ¿stent shaft broken¿ are written on the label.Product analysis: the device was received for analysis.The device returned with a detachment on the hypotube.Kinks were evident on the hypotube proximal to the detachment site.The hypotube material was oval and jagged on both sides of the detachment site.The stent was positioned on the balloon between the marker bands as per position specification, but due to distal stent misalignment and flaring, the stent did not meet visual acceptance specification.Misalignment was evident to the distal stent wraps with struts slightly flared.No other damage evident to the remainder of the device.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.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.
