New stent aims to keep dialysis lifelines flowing
NCT ID NCT05062291
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at a special stent called WRAPSODY used to treat narrowed or blocked veins in people on dialysis. About 500 participants will be followed for up to 24 months to see how well the stent keeps the access site open and safe. The goal is to improve long-term dialysis care.
