Additional Manufacturer Narrative
Additional information: it was detailed that both stents were damaged as they advanced inside the telescope gec on ramp.A 4.5mm medtronic stent was able to pass through and be deployed, through the same telescope the 5.00mm onyx frontier stents couldn't pass through.Product analysis: the device was received for analysis.The stent was not positioned on the balloon between the marker bands as per position specification but was displaced proximally over the proximal marker band.Due to distal stent deformation the stent did not meet visual acceptance specification.Deformation was evident to the distal stent wrap with struts raised.Bunching was evident to the distal tip.The inner lumen could not be verified with a 0.015 inch mandrel most likely due to deformation of the tip.An attempt was made to pass the stent through an in-house telescope guide extension catheter, but due to the deformed stent struts this was not possible.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.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.
