Eligibility

Inclusion Criteria:

• Patient is legally competent, has been informed of the study, voluntarily agrees to participate, and has signed the informed consent form.
• Arteriovenous fistula is located in the arm.
• Native AV fistula / graft was created = 30 days prior to the initial procedure and has undergone at least one hemodialysis sessions.
• Venous stenosis of the AV fistula / graft with the target lesion located from the anastomosis to the axillosubclavian junction and an abnormality attributable to the stenosis as defined by K/DOQI guidelines.
• Patients with a dysfunctional or thrombosed hemodialysis access and a >50% stenosis, regardless of prior treatment (All types of lesion and access failure)
• If AV access is thrombosed, must undergo a successful thrombectomy with minimal residual thrombus.
• Intended target lesion or if a tandem lesion can be treated with =120 mm of DCBs in length.

Exclusion Criteria:

• Women who are pregnant, lactating, or planning on becoming pregnant during the duration of the study.
• The hemodialysis access is located in the leg.
• Patient has more than two lesions in the access circuit.
• Patient has a secondary non-target lesion that cannot be successfully treated
• Target lesion is located central to the axillosubclavian junction.
• Surgical revision of the access site planned.
• Recent surgical interventions of the access site.
• Known allergy or sensitivity to iodinated contrast media, that cannot be adequately managed with pre- and post-procedure medication.
• Known allergy or sensitivity to paclitaxel.
• Patients who are taking immunosuppressive therapy, or routinely taking = 10 mg of prednisone per day.
• Patients who have a medical condition, in the opinion of the Investigator, that may cause the patient to be noncompliant to the protocol or confound the data.
• Patients anticipating a kidney transplant.
• Patients anticipating a conversion to peritoneal dialysis.
• The patient has a stent located in the target or secondary non-target lesion.
