About

This prospective, multicenter, randomized, controlled study is designed to evaluate the safety and effectiveness of the Tri-wire Peripheral Balloon Dilatation Catheter compared to a standard PTA Catheter in treating subjects presenting with clinical and hemodynamic abnormalities in native arteriovenous (AV) fistulae located in the upper extremity.

  4. Reference vessel diameter of target lesion from 3.0 mm to 8.0 mm.
  5. Target lesion located from proximal to the anastomosis to the reflux vein at the distal end of the subclavian vein.
  6. De novo or restenosis lesion.
  7. Single or tandem lesion, length of which ≤ 60mm.

Exclusion criteria

  1. Women who are pregnant, nursing, or planning to become pregnant during the study.
  2. Patients who have accepted major surgeries within 30 days prior to the enrollment. (such as thoracic surgery, cranial surgery).
  3. Patients who plan to accept major surgeries within 30 days after the enrollment. (such as thoracic surgery, cranial surgery).
