Post Approval Study Investigating Lutonix Drug Coated Balloon for Treatment of Dysfunctional Arteriovenous Fistulae

This post-market approval study (PAS) is required by the FDA as a condition of approval for the Lutonix drug coated balloon catheter. It is intended to demonstrate safety and assess the clinical use and outcomes of the LUTONIX Catheter in dysfunctional arteriovenous fistulae (AVF) in a heterogeneous patient population in real world clinical practice.

Inclusion criteria

• Male or non-pregnant, non-breastfeeding female ≥18 years of age
• Subject is willing to provide informed consent, and is willing to comply with the protocol-required follow up visits
• Target lesion must be a mature arteriovenous fistula located in the arm presenting with any clinical, physiological or hemodynamic abnormalities warranting angiographic imaging as defined in the K/DOQI guidelines
• Subject has a target lesion that can be treated with available LUTONIX DCB according to the Instructions For Use (IFU)
• Venous stenosis of an AV fistula in which the target lesion is located from the anastomosis to the axillosubclavian junction, as defined by insertion of the cephalic vein
• Successful pre-dilation of the target lesion with an uncoated percutaneous transluminal angioplasty (PTA) balloon defined as:

• No clinically significant dissection;
• No extravasation requiring treatment;
• Residual stenosis ≤30% by angiographic measurement;
• Ability to completely efface the waist using the pre-dilation balloon.

Exclusion criteria

• Subject is currently participating in an investigational drug, biologic, or device study, or previous enrollment in this study
• Subject has a non-controllable allergy to contrast
• Subject has another medical condition that, in the opinion of the Investigator, may confound the data interpretation or is associated with a life expectancy insufficient to allow for completion of subject study procedure and follow up
• Target lesion is located central to the axillosubclavian junction
• A thrombosed access or an access with a thrombosis treated ≤7 days before to the index procedure
• Prior surgical interventions of the access site ≤30 days before the index procedure
• Target lesion is located within a bare metal or covered stent
