This single-centre, single-arm, prospective study will enroll 30 subjects presenting with clinical and hemodynamic abnormalities in arteriovenous graft (AVG) in the arm. Subjects will be treated with the Jetstream atherectomy device and Ranger Drug Coated Balloons (DCB). Subjects will be followed up clinically via office visit or phone visit at 6 and 12 months post procedure. This study is to demonstrate safety and assess the clinical use and outcomes of the Jetstream atherectomy device and Ranger DCB for the treatment of dysfunctional AV graft.
