Interventions and Outcome Measures

Arms

active comparator: Stage 1: SOC First

This group will be cannulated using Standard of Care techniques only for the first three dialysis sessions, and the 7th, 8th, and 9th dialysis session. The first group will be cannulated using EchoMap in support of standard techniques for the 4th through 6th dialysis session, and again for the 10th through 12th session.

experimental: Stage 1: EchoMap First

This group will be cannulated using EchoMap in support of Standard of Care for the 1st through 3rd dialysis session, and the 7th through 9th dialysis session. The second group will be cannulated using Standard of Care techniques for the 4th through 6th dialysis session, and again for the 10th through 12th session.

active comparator: Stage 2: SOC

Subjects will undergo standard cannulation practices only.

experimental: Stage 2: EchoMap

Subjects assigned to the EchoMap arm, for 12 dialysis sessions they will be cannulated using EchoMap in support of Standard of Care only. For

Interventions

EchoMap

EchoMap is a vascular ultrasound imaging device meant to aid in identification of the cannulation site on the skin of mature arteriovenous fistulas/grafts (AVFs/AVGs) in adult patients by appropriately trained healthcare providers in clinical settings. This device is not meant to replace the current Standard of Care cannulation methods.

Standard of Care Cannulation

Dialysis technicians will use the rope ladder or area cannulation technique (not button hole) to avoid repeat cannulation in the same location.
