Arm Intervention/treatment
Experimental: Interventional Arm Device: Velocity pAVF system
A second generation percutaneous AVF device that creates an AVF between the proximal radial artery and cubital perforating vein.

Primary Outcome Measures :
  1. Procedural Success [ Time Frame: Immediate ]
    Defined as Velocity deployment and delivery system withdrawal with intraprocedural duplex ultrasound demonstrating arterialized flow in the cephalic vein 2 cm central from the pAVF anastomosis

  2. Serious Adverse Device Events [ Time Frame: 6 weeks ]
    Defined as any Serious Adverse Event that reasonably suggests is caused by the device or procedure.

  3. Major Reintervention [ Time Frame: 6 weeks ]
    Defined as any open surgery, thrombectomy or thrombolysis in the index limb following pAVF creation.

  • Eligible for a native surgical brachiocephalic arteriovenous fistula following assessment by the principal investigator and study sponsor
  • Cubital perforating vein diameter of > 2.5 mm and length > 10.0 mm

  • Patients with occlusion of the ulnar or radial artery at any level or an abnormal Allen's test
  • Any previous dialysis vascular access procedures in the study extremity
  • History of steal syndrome (hand ischemia) from a previous hemodialysis vascular access of the non-study extremity which required intervention or access abandonment
  • Upper extremity venous occlusion(s) and/or vessel abnormality(ies) of the study extremity that precludes endovascular AVF creation as determined by principal investigator or study sponsor
  • Evidence of active systemic infections on day of the procedure or infection at the access site within the past 7 days
