Manufacturer Narrative

The lot history records are being reviewed.The event is currently under investigation.

Event Description

It was reported that during a stenting procedure for treatment of a central venous stenosis in the brachiocephalic vein, the endovascular stent graft could not be deployed.Another stent graft of the same brand was used to complete the procedure successfully.There was no reported patient injury.

Manufacturer Narrative

The lot history records have been reviewed with special attention to the manufacturing and inspection of this product and the product was found to have met all specifications prior to shipment.There is no indication for a manufacturing-related failure.On the basis of the sample evaluation, the reported deployment failure could be confirmed.The stent graft was found to be loaded in the system.The outer sheath was found to be slightly elongated on its entire length indicating that increased friction must have affected on the whole system.The stent graft could not be deployed during sample evaluation.The distal tip was found to be in good condition.Based on the sample condition, the reported difficulties in advancing the system to the lesion site could not be reproduced.Potential factors which may have contributed to the reported event have been considered.Previous investigations of similar complaints have been reviewed.The reported event may be associated with a difficult vessel anatomy which can lead to increased friction during the attempt to deploy the stent graft.Reportedly, the vessel had been pre-dilated and the anatomy of the tracking path was not tortuous or calcified.However, it was reported that it was difficult to advance the delivery system to the lesion site and the proximal end of the stent graft could not be placed in a straight section of lumen prior to stent graft deployment as it was difficult to move the system to the correct position.Insufficient flushing of the device may be another contributing factor to the reported event.On the basis of the information available, a definite root cause for the reported event could not be determined.The ifu states that the device must be flushed with sterile saline.Also the ifu states: "the safety and effectiveness of the device when placed across a tight bend (.) has not been evaluated.Prior to stent graft deployment, ensure that the proximal (inflow) stent graft end is positioned in a straight section of the lumen to reduce the risk of higher deployment forces and possible endovascular system failure." and "do not kink the delivery catheter or use excessive force during delivery to the target lesion." furthermore, the ifu states: "if unusual resistance or high deployment force is encountered during stent graft deployment, abort the procedure, remove the delivery system and use an alternative device.".
