Medical Device Problem Codes	Positioning Failure (1158); Fracture (1260)
Health Effect - Clinical Code	No Consequences Or Impact To Patient (2199)
Date of Event	03/06/2017
Type of Reportable Event	Malfunction
Additional Manufacturer Narrative
The device history records are being reviewed.The event is currently under investigation.The information provided by bard represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant was unable to provide any further patient or procedural details to bard.
Event or Problem Description
It was reported that during deployment of the endovascular stent graft in the left cephalic vein via access through the left brachiocephalic vein, the outer catheter broke when the stent graft was being deployed approximately halfway.The delivery system with the partially released stent was removed without incident.Another device was used to complete the procedure successfully.There was no reported patient injury.
Additional 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.The evaluation of the returned device confirmed that the delivery system had been actively used and that the outer sheath fractured distal to the grip.An elongation was detected in the area of the fracture indicating the presence of high release force during the attempt to deploy the stent graft.The stent graft was not returned and therefore, a deployment failure could not be confirmed.Potential contributing factors to the reported event have been considered.Previous investigations of similar complaints have been reviewed.The reported event may be related to a difficult vessel anatomy leading to increased friction and subsequent sheath fracture.Insufficient flushing of the device may be another contributing factor to the reported event.Reportedly, the lesion had been pre-dilated but the system was used without introducer sheath which is considered another contributing factor to the reported event.On the basis of the information available and the evaluation of the returned device, a definite root cause for the reported failure 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." and "examine the packaging and endovascular system to determine if there is any damage, defects or if the sterile barrier is compromised.Do not use the device if any of these conditions are observed." in addition, the ifu indicates that an introducer sheath of appropriate inner diameter is required for the procedure.The reported application represents an off-label use of the device.The ifu states that 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 (av) fistula or av graft and for the treatment of stenosis in the venous outflow of hemodialysis patients dialyzing by an av graft.
