The objective of this clinical study is to evaluate the performance of the Optimized FLAIR™ Delivery System.


Inclusion Criteria: - The subject is either a male or non-pregnant female ≥ 18 years old. - The subject has been properly informed about the study per IRB requirements, and has signed and dated the IRB-approved ICF. - The subject is willing to comply with the protocol requirements and can be contacted by telephone. - The subject has a synthetic AV access graft located in an arm that has been implanted for > 30 days and has undergone at least one successful dialysis session prior to the index procedure. - Angiographic evidence indicates that the subject has a stenosis of >50% located at the graft-vein anastomosis of the subject's synthetic AV access graft. - The target lesion is estimated to be ≤ 7 cm in length by angiography prior to performance of any interventional procedures. - The entire target lesion is located within 7 cm of the graft-vein anastomosis, as verified by angiography, such that approximately 1 cm of the FLAIR™ Endovascular Stent Graft will extend into non-diseased vein and approximately 1 cm but no more than 2 cm of the FLAIR™ Endovascular Stent Graft will extend into non-diseased AV graft. - Graft diameter at the deployment site is between 5 mm and 8 mm, as verified by angiography. - Full expansion of an appropriately sized angioplasty balloon, in the operator's judgment, can be achieved during primary angioplasty. Exclusion Criteria: - The subject has a life expectancy of < 6 months. - The presence of a previously placed stent and/or stent graft located in the treatment area. The treatment area is defined as the entire target lesion and 1 cm of landing zone into both non-diseased AV graft and non-diseased vein. - The subject has an infected AV access graft or other infection. - The location of the target lesion would require that the FLAIR™ Endovascular Stent Graft be deployed fully across the elbow joint. - The location of the target lesion would require that the FLAIR™ Endovascular Stent Graft cross an angle (between the outflow vein and synthetic AV access graft) that is > 90 degrees. - The subject has an uncorrected blood coagulation disorder. - The subject has a known allergy or sensitivity to contrast media which cannot be adequately pre-medicated. - Subject is currently enrolled or scheduled to be enrolled in other investigations that conflict with follow-up testing or confounds data in this trial. - The subject has a known hypersensitivity to nickel-titanium.

Study Outcomes

Outcome Type:Primary Outcome
Measure:Technical Success for Delivery
Time Frame:Measured at the time of implantation (Day 0)
Safety Issues:False
Description:defined as deployment of the implant to the intended location, assessed at the time of the index procedure.
Outcome Type:Secondary Outcome
Measure:Number of Device/Procedure-related Adverse Events(Safety of Delivery)
Time Frame:Index Procedure to 30 days
Safety Issues:True
Description:Device/Procedure-related adverse events from the index procedure through 30 days post procedure

Study Interventions

Intervention Type:Device
Name:FLAIR™ Endovascular Stent Graft
Description:The FLAIR™ Endovascular Stent Graft is designed to treat venous anastomotic stenoses of AV access grafts, providing both structural support of the site following angioplasty (stent), and a barrier to locally recurrent flow-limiting neointimal tissue growth (covering/graft).
