What this trial studies
This clinical trial aims to gather data on the safety and effectiveness of Acotec Orchid and Dhalia drug-coated balloon catheters for treating stenosis in native hemodialysis arteriovenous fistulas. It is a prospective, multi-center, single-arm study that focuses on patients with obstructive lesions in their dialysis fistulas. Participants will undergo treatment with the drug-coated balloon catheter after meeting specific eligibility criteria, including having a significant blockage in their fistula. The study will monitor outcomes related to the procedure's safety and performance.
Why it matters
Potential benefit: If successful, this treatment could improve blood flow and overall function of dialysis fistulas, enhancing patient outcomes.
How similar studies have gone: Other studies using drug-coated balloons for similar vascular conditions have shown promising results, indicating potential for success in this approach.
