Event Description

Physician intended to use a protégé rx carotid stent system with a spider fx embolic protection device during treatment of a fibrous lesion in the patient¿s proximal common carotid artery.Moderate vessel calcification and moderate vessel tortuosity are reported.Lesion exhibited cto (chronic total occlusion-100%) stenosis.There was no damage noted to packaging (i.E.Shelf carton, hoop/tray).There were no issues noted when removing the device from the hoop/tray.Device prepped per the ifu with no issues identified.No resistance was encountered during delivery to the lesion and no excessive force was used.The thumbscrew/lock-pin was checked for securement prior to procedure.The lock-pin was removed during the surgery.Stent deformation occurred in vivo during positioning/deployment.The stent was also unable to deploy.A replacement non-medtronic stent was used to complete procedure.No patient injury reported.

Manufacturer Narrative

Additional information: the stent was suspected to be deformed, because when the stent reached the lesion position, it drove the guide wire of the spider to move, causing the spider to shift.The stent failed to reach the lesion, so the initial end did not bloom.Removing the device required no special intervention and the device was safely removed from the patient.No stent struts were exposed/visible on removal.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.
