Brief Summary This prospective, single arm, single-center study is designed to evaluate the performance of the FLEX Scoring Catheter®/POBA/DCB in A-V access circuits.
Detailed Description Not Provided
Study Type  ICMJE Interventional
Study Phase  ICMJE Not Applicable
Study Design  ICMJE Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE Arteriovenous Fistula

Eligibility Criteria  ICMJE

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:

  • 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.
