  • Treatment of Raynaud’s phenomenon
  • Non-pharmaceutical vasorelaxation

Technology Overview

Raynaud’s phenomenon is a rare disorder that causes arteries to spasm leading to reduced blood flow in areas such as the fingers and toes. Currently, treatment options for Raynaud’s phenomenon are extremely limited and ineffective in most patients. Researchers at the University of Minnesota have developed a medical device for the non-pharmaceutical treatment of Raynaud’s Phenomenon. A light treatment unit causes vasorelaxation to occur by exposing hands, or other parts of the body, to specific wavelengths of blue light and heat. This reverses the spasming of arteries and restores blood flow.
