Manufacturing review: the device history records have been reviewed with special attention to the manufacturing and inspection of this product.This lot meets all release criteria.There was nothing found to indicate there was a manufacturing related cause for this event.This is the first complaint that has been reported for this corporate lot number to date.Visual/dimensional inspection: the device was returned.Safety clip was missing upon receipt.The tuohy borst adapter was loose and the two-way stop cock was open.The gray outer sheath was torn off approximately 54mm from the strain relief at the catheter reinforcement area.Stretching in the outer grey catheter was noted at the break.The gray outer catheter was bent throughout the length of the delivery system.The stent graft was found to be released and was not returned with the delivery system.The inner green catheter was noted to be kinked.No other anomalies were noted.Functional/performance evaluation: functional testing could not be performed, as the delivery system was returned with stent graft deployed.Medical records review: medical records were not provided; therefore, a review could not be performed.Photo review: two digital images were reviewed.The first image is of the product label identifying the product.The second image shows the proximal end of the delivery system against a white sterile sheet.A break can be identified near the catheter reinforcement area of the device.It is unknown where the stent graft was deployed or not in the image as the distal end of the delivery system is not visible.The investigation is confirmed for a break in the outer catheter.Conclusion: the investigation is confirmed for a break, as a complete circumferential break was noted on the returned delivery system.The root cause could not be determined based upon available information.It is unknown whether patient and/or procedural issues contributed to the event.Labeling review: the current ifu (instructions for use) state: indication for use: the flair endovascular stent graft is indicated for use in the treatment at the venous anastomosis of eptfe or other synthetic arteriovenous (av) access grafts.Warnings: the stent graft (implant) cannot be repositioned after total or partial deployment.Once partially or fully deployed, the flair endovascular stent graft cannot be retracted or remounted onto the delivery system.Device removal after deployment can only be done with a surgical approach.Precautions: the safety and effectiveness of this device have not been established when used around a tight bend in a looped av graft.It is recommended to access the av graft at the venous side of the av graft or at the apex.Careful attention should be paid to ensure the device is appropriately sized to the actual graft diameter, taking into account any change to the stated graft diameter that may have resulted from previous interventions.The appropriate length device(s) should be selected so that the stent graft extends beyond the stenosis into at least 10 mm of the non-diseased graft towards the arterial inflow and into the non-diseased vein approximately 10 mm beyond the stenosis.During deployment of the stent graft, the entire length of the delivery system should be kept as straight as possible in order to mitigate the potential for distal stent graft misplacement.After full stent graft deployment, wait a few seconds to allow for complete device expansion before removing the delivery system over the guidewire.Stent graft dislodgement has been reported during removal of the delivery system; therefore, careful attention should be paid during this portion of the procedure to prevent such occurrences.In case of placement of two stent grafts (overlap), use the same device diameter in both cases.If a flared device is used to overlap, do not deploy the flared end inside the first stent graft.Ensure a minimum 10 mm overlap of the devices.Potential complications and adverse events: stent graft specific events that could be associated with clinical complications include stent graft misplacement, stent graft migration, stent graft fracture, stent graft kinking, insufficient stent graft expansion and stent graft embolism.Delivery system specific events that could be associated with clinical complications include bond joint failures, detachment of parts, incompatibility with accessory devices, premature deployment, inaccurate deployment, failure to deploy, high deployment forces, delivery system kinking, no visibility under fluoroscopy, inability to track to target location, and blood leakage from delivery system (hemostasis).Stent graft size selection: special care must be taken to ensure that the appropriate size flair endovascular stent graft is selected.The stent graft body diameter should be approximately 1 mm larger than the synthetic av access graft diameter.The information provided by bard 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 bard.

It was reported that during deployment of the endovascular stent graft in the arterial limb of a graft, the hcp encountered slight resistance and the outer catheter of the endovascular stent graft delivery system allegedly broke.There was no reported retraction difficulty through the sheath.Reportedly, the stent graft was successfully deployed and the procedure was completed.There was no reported patient injury.
