New implant aims to make dialysis easier for kidney patients
NCT ID NCT06516653
First seen Jun 27, 2026 · Last updated Jul 15, 2026 · Updated 2 times
Summary
This study tests a device called VasQ that is placed around a blood vessel connection (fistula) used for dialysis in people with kidney failure. The goal is to see if VasQ helps the fistula work well enough for dialysis sooner and for longer compared to standard fistula creation. About 300 adults who need a new dialysis fistula will take part and be followed for 12 months.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Patients who are candidates for the creation of a new radiocephalic or brachiocephalic end-to-side surgical AV fistula for dialysis access (per VasQ IFU and investigator clinical judgment) and consent to take part in the study. 2. Male and non-pregnant female participants. 3. Age 18-80 years 4. Patients willing and able (physically and geographically) to attend follow up visits over a period of 12 months. Exclusion Criteria: 1. Index procedure being a revision surgery of an existing fistula. 2. Significantly stenotic target vein on the side of surgery (≥50%) as diagnosed on preoperative ultrasound. (Scan should include the full length of the expected fistula outflow, starting at the planned anastomosis site) 3. Unusual anatomy or vessel dimensions (observed on pre-operative ultrasound or intraoperatively) and which preclude adequate fit of the VasQ. 4. Known central venous stenosis or obstruction on the side of surgery. 5. Pre-existing stents or stent grafts in the access circuit. 6. Planned subsequent fistula superficialization procedure. 7. Known coagulation disorder. 8. Known allergy to nitinol. 9. Expected kidney transplant within 12 months of enrollment. 10. Inability to give consent and/or comply with the study follow up schedule. 11. Insufficient or borderline life expectancy to allow for completion of study procedures and follow-up (12 Months). 12. Participation in another interventional study that in the judgment of the investigator could confound study results.
