The lot 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.On the basis of the evaluation of the returned delivery system it could be confirmed that the stent graft could not be deployed and that the outer sheath was fractured.No indication was found for manufacturing related issues.Potential factors which may have contributed to the reported issue have been considered.Previous investigations of similar complaints have been reviewed.The event may have been associated with difficult anatomic conditions, which led to increased friction during deployment.Also, insufficient flushing of the device could be another contributing factor for the event.As reported no introducer sheath was used, which could be also a potential contributing factor.Based on the available information and the evaluation of the returned sample, 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.¿ furthermore, the ifu states: ¿do not kink the delivery catheter or use excessive force during delivery to the target lesion.¿ and ¿prior to loading the endovascular system over a guide wire, both ports must be flushed with sterile saline (¿).Flushing these lumens will also facilitate stent graft deployment.¿ additionally, the ifu states that the materials required for the fluency plus endovascular stent graft procedure are ¿(.) introducer sheath with appropriate inner diameter (.)¿.
