- Subject is willing to undergo all follow-up assessments.
- Subject has a life expectancy ≥ 12 months.
- Subject is undergoing chronic hemodialysis.
- Subject has either a mature AVF or AVG in the arm.

WRAPSODY Stent Graft
Arm Description
All subjects will receive treatment via WRAPSODY Stent Graft Placement.
Outcomes
Primary Outcome Measures
Proportion of subjects without any localized or systemic safety events (Primary Safety Endpoint
Proportion of subjects without any localized or systemic safety events through 30 days post-index procedure that affect the access or venous outflow circuit and resulted in intervention, hospitalization, or death.
Proportion of subjects with Target Lesion Primary Patency (TLPP) (Primary Effectiveness Endpoint)
Proportion of subjects with Target Lesion Primary Patency (TLPP) at 6 Months. TLPP is defined as freedom from clinically-driven target lesion revascularization (CD-TLR) or target lesion thrombosis measured through 6 months post-procedure, which is the time interval of uninterrupted patency after study procedure to the next intervention performed on the target lesion or uncorrectable target lesion occlusion.
Secondary Outcome Measures
Proportion of subjects with Target Lesion Primary Patency
Proportion of subjects with Assisted Target Lesion Primary Patency (aTLPP)
Proportion of subjects with Access Circuit Primary Patency (ACPP)
Proportion of subjects with Post-Procedure Secondary Patency
Rates of procedure- and device-related adverse events involving the access circuit
