Detailed Study Protocol Parameters
Study Objectives This is a prospective, multi-center, non-randomized, single- arm, post-market study for endoAVF creation in United States (U.S.) patients who require vascular access for hemodialysis. Follow-up for all treated subjects will be performed at discharge, 2-weeks, 6-weeks, 3-, 6-, 12-, 18- and 24- months post index procedure.
Study Population The study will enroll subjects who are either already receiving dialysis at the time of screening, regardless of access type (Central Venous Catheter (CVC), AV Fistula (AVF), AV Graft (AVG)), or are anticipated to need hemodialysis access for dialysis initiation in the near future. In addition, the study will make all reasonable efforts to treat a population that consists of at least 30% African Americans and have no single study site constitute more than 15% of the total study population.
Sample Size No. of subjects: 280
A maximum of 60 of the total treated population can be pre-dialysis at the time of index procedure. All subjects will be followed for 24 months post index-procedure.
No. of sites: 40
Site’s location: US
Key Study Endpoints Two primary effectiveness endpoints will be evaluated independently: the percentage of subjects with functional cannulation success through 6-months and primary patency through 6-months.

The primary safety endpoint is freedom from device-related or procedure-related serious adverse events (SAE) through 30 days.
Secondary Endpoints will include the following: Procedure Success
Cannulation Success Primary Patency Assisted Primary Patency Secondary Patency Functional Patency Functional Cannulation
Physical and Physiological Maturation CVC Exposure/Use
Procedural Adjunctive Procedures Post Procedural Secondary Procedures

Training Effectiveness Serious Adverse Events Adverse Events
Unanticipated (Serious Adverse) Device Events
Follow-up Visits and Length of Follow-up Subjects will be followed up through 24 months.
Follow-up for all treated subjects will be performed at
discharge, 2-weeks, 6-weeks, 3-, 6-, 12-, 18- and 24-months post index procedure.
