Manufacturer Narrative

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

Event Description

It was reported that during a sheathless stenting procedure of the right mid to distal tortuous and/or calcified sfa via left cfa access, the endovascular stent graft failed to deploy properly.Reportedly, the sheath of the delivery system snapped in half when the distal 3rd of the stent graft was being partially released with difficulty.The stent graft was removed through the puncture site leading to a bleeding complication, a hematoma of the left groin and thigh as well as a second angiogram to treat the bleeding and achieve hemostasis.As reported, no other device was used to complete the procedure.The patient is reported to be in stable condition.

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 evaluation of the returned device, the reported event could be confirmed.The stent graft was found to be partially deployed which may have caused the reported removal issues.Furthermore, the outer sheath was found to be elongated indicating that increased friction must have affected on the delivery system during the attempt to deploy the stent graft finally leading to the reported sheath fracture and subsequent deployment failure.Potential contributing factors to the reported event have been considered.Previous investigations of similar complaints have been reviewed.The event may be associated with difficult anatomic conditions leading to increased friction during stent graft deployment and subsequent sheath fracture.In this case, the vessel anatomy was reported to be tortuous and calcified.The indication for the stent graft placement was a subintimal recanalization in the sfa.Insufficient flushing of the device may be another contributing factor to the reported event.Also not using an introducer sheath may contribute to this type of event.On the basis of the information available, a definite root cause for the reported event could not be determined.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 of the same size." and "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." also the ifu indicates that the device must be flushed with sterile saline and that an introducer sheath with appropriate inner diameter is required for the procedure.Furthermore, the ifu states: "do not kink the delivery catheter or use excessive force during delivery to the target lesion." the reported application represents an off-label use of the device.The fluency plus endovascular stent graft is indicated for use in the treatment of in-stent restenosis in the venous outflow of hemodialysis patients dialyzing by either an arteriovenous (a/v) fistula or a/v graft.
