Brief Summary:
This is a single center pilot study that is seeking to determine whether the use of the Fist Assist® device for 360 hours over 90 days by patients with advanced CKD prior to AVF surgery results in significant increases in cephalic vein diameters prior to AVF surgery.

Arm Intervention/treatment
Experimental: Fist Assist device (all subjects)

All study subjects will have Stage 4 or 5 Chronic Kidney Disease (CKD) that requires them to start hemodialysis. In preparation for hemodialysis, they will have an arteriovenous fistula (AVF) procedure which provides access to the veins for dialysis.

This study is testing a device called the Fist Assist to dilate the vein in preparation for dialysis. The device is similar to a blood pressure cuff (worn around the arm and applies pressure). All study participants will wear the Fist Assist twice a day up to three months before their AVF procedure.

Device: Fist Assist

The Fist Assist device works by applying pressure to the subject's arm in the area where their arteriovenous fistula will eventually be created. The device is mobile and battery powered.

The Fist Assist device will be assigned to each enrolled subject by randomization code. All subjects will be asked to use their assigned device twice daily, for two 2-hour sessions, once in the morning and once in the evening. Patients will apply the device to the non-dominant arm above the level of the elbow, and to keep a written log to record use, complications and any problems. They will be asked to do this for 3 months, and will come in to be evaluated via study visits at Months 3, 6, 9 and 12.

Primary Outcome Measures :
  1. Vein diameter [ Time Frame: 3 months ]
    The primary outcome will be the difference in the vein diameter measured in millimeters with use of a vascular ultrasound device before and after Fist Assist use. The standard deviation of the change in vein diameter will be approximately 0.75mm.

Secondary Outcome Measures :
  1. AVF creation [ Time Frame: 12 months ]
    Whether or not an arteriovenous fistula was created, as defined by a procedure performed by surgery or interventional radiology connecting an artery to a vein.

  2. AVF maturation [ Time Frame: 12 months ]
    Whether the resultant AVF matured, as defined successful cannulation with two needles for three hemodialysis treatments.

  3. Subsequent exposure to central venous catheters [ Time Frame: 12 months ]
    The subject's subsequent exposure of patients to central venous catheters during their first year for hemodialysis as measured in total number days of central venous catheter access used for hemodialysis.
