Fist Assist is a novel, non-invasive, external device which uses a pneumatic balloon for intermittent vein compression.

Vein dilation can assist in hemodialysis fistula development and phlebotomy procedures.

Changing the Standard of Vein Dilation

** The Fist Assist FA-1 device is cleared for sale in the USA as an arm massager and increase circulation device.

There is a need for simple, cost-reducing, patient empowering device to assist in global vein dilation.

How it Works

The Fist Assist device is an external medical intermittent pneumatic compression device that can apply intermittent pressure to a specific arm vein that may help dilate the vein for eventual AV fistula placement and blood draw.

The Problem:

  • Over 400k patients in the US receive hemodialysis for end-stage renal disease (ESRD): 150k new patients start hemodialysis yearly.
  • Hemodialysis costs an average of $89,000 per patient annually in the US; a total annual cost of $42 billion (significant portion is maturation and catheter issues)
  • AV fistulas are the preferred method of vascular access for hemodialysis
  • 70% of fistulas thrombose or require corrective procedures to maintain or restore blood flow within 1 year of initial surgery
  • Basic science and clinical studies demonstrate the importance of vein enlargement

Chronic Kidney Disease: A Global Opportunity

1 in 10 Adults
Will have some form of chronic kidney disease (CKD)
40 Million Americans
Are currently classified as having CKD
3.6 Million Patients
Worldwide currently have stage 5 CKD or End Stage Renal Disease (ESRD)
4.9 Million Patients
Worldwide will be on dialysis by 2025


Develop & produce a novel, non-invasive, low cost device to:

  • Assist with Fistula Maturation
  • Assist with Venous Pre-surgery preparation
  • Decrease total catheter contact time and fistula development time
  • Improve fistula maturation and cannulation
  • Significantly reduce costs in treating Stage 4 and ESRD markets
  • Empower patients to have a device for vein dilation and phlebotomy
