Study Summary

This trial will look at how well the Ellipsys Vascular Access System works in people who need an AV fistula.

Who is the study for?
This trial is for adults aged 18-80 with chronic kidney disease or on hemodialysis needing an arteriovenous (AV) fistula. Candidates must have certain vein and artery sizes, be medically eligible for AV fistula creation, and able to attend follow-ups. Exclusions include upper extremity edema, bleeding disorders, active infections including COVID-19, scheduled kidney transplant within 6 months, substance abuse history, low blood pressure at screening time.Check my eligibility
What is being tested?
The Ellipsys Vascular Access System is being observed in this study. It's a single-arm post-market surveillance of the system used to create AV fistulas in patients who need them due to kidney conditions. The study will monitor how well it works and its safety after being approved for use.See study design
What are the potential side effects?
While specific side effects are not listed here as it's observational post-market surveillance focusing on the performance of the Ellipsys Vascular Access System after approval; generally such procedures may cause discomfort at the access site, possible infection risk or issues related to vascular access.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Does the research team consider minors for enrollment in this trial?

"Participants in this medical experiment must be under 80 years old and of legal age."

Answered by AI

What goals is this endeavor hoping to accomplish?

"This trial intends to measure Early Occlusion Rate at 7 days post-intervention as its principal objective over a timeframe of 12 months. Secondary objectives include Primary Patency Through 12 Months Post-AVF Creation, Assisted Primary Patency Through 12 Months Post-AVF Creation, and the Secondary Procedures Rate which records interventions aimed at maturing or sustaining the AVF's flow per person year."

Answered by AI

Are there any American locations currently undergoing this clinical experiment?

"Both The Vascular Care Group in Hyannis, Massachusetts and Yale University in New Haven, Connecticut are participating sites for this research endeavour. Rush University Medical Center located in Chicago is also aiding with the study's progression along with 6 other medical centres."

Answered by AI

How many participants have been accepted into this experiment?

"Indeed, clinicaltrials.gov shows that this research initiative, initially posted on April 13th 2021, is actively enrolling participants. A total of 134 individuals must be recruited from 6 different medical sites."

Answered by AI

Is this research currently enrolling volunteers?

"According to clinicaltrials.gov, this research is still recruiting participants who meet the criteria stated in the initial post of April 13th 2021 and updated on October 6th 2022."

Answered by AI

May I be part of this investigation?

"This clinical trial seeks to enrol 134 individuals who are aged between 18 and 80, have been diagnosed with End-Stage Renal Disease (ESRD) or Chronic Kidney Disease on hemodialysis, and can live for at least a year. Applicants must possess an arterial lumen of ≥2.0 mm in the target area along with adequate collateral perfusion as established by Barbeau Test; be medically qualified for upper extremity autogenous AV fistula formation per institutional guidelines/clinical judgement; demonstrate sufficient quality vein & radial artery based on preoperative assessment; display an adjacent vein diameter of ≥2.0 mm at"
