Fist Assist Devices

Fist Assist is a private medical device company developing and commercializing a wearable intermittent pneumatic compression device designed to dilate arm veins. Its lead product, the Fist Assist FA-1, is intended to support vein enlargement for hemodialysis fistula development and blood-draw/phlebotomy use cases. The company positions the technology as a non-invasive, low-cost approach to improving vascular access preparation, particularly for chronic kidney disease and end-stage renal disease patients. Fist Assist has reported clinical work including the FACT trial and has received FDA Breakthrough Device designation for a presurgical vein-dilation indication, while the FA-1 is marketed in the U.S. as a 510(k)-cleared arm massager and circulation device. The company also appears to commercialize through a distribution relationship with AIROS Medical.
