Event Description

It was reported that during a stent graft placement procedure, the stent was allegedly failed to deploy.It was further reported that stent was removed.The procedure was completed using another device.There was no reported patient injury.

Manufacturer Narrative

H10: a voluntary recall has been initiated for the covera vascular covered stent which was product catalog/lot number specific.Reportedly the covera vascular covered stent has the potential to exhibit deployment issues (i.E., failure to deploy the covered stent) due to slide block bond failures in the device handle.Full or partial failure of the product to deploy is most likely to require percutaneous replacement with existing access.In rare cases, iatrogenic vascular injury may occur as the result of device withdrawal, manipulation, or abrupt/unexpected movements, particularly in the context of difficult or partial stent deployment or mispositioning.Adjunctive endovascular maneuvers may be indicated.There have been no cases where an open surgical procedure has been required.To date, there have been no reported patient injuries associated with deployment issues.As a result of the field action, this event is being reported as a malfunction reportable event.  h10: as the lot number for the device was provided, a review of the device history records will be performed.The device has been returned to the manufacturer for evaluation.The investigation of the reported event is currently underway.H10: d4 (expiry date: 10/2023).H11: section a through f - the information provided by bd represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.

Event Description

It was reported that during a stent graft placement procedure in the cephalic arch, the stent was allegedly failed to deploy.It was further reported that the stent was removed.The procedure was completed by using another device.There was no reported patient injury.
