About

For more than 40 years, members of the Delfi team have been extensively involved in improving surgical tourniquet safety through the development and evaluation of new technologies.   

The team is led by James McEwen, Ph.D., P.Eng. Dr. McEwen is the inventor of the automatic surgical tourniquet, and holds patents for much of the advanced tourniquet technology that is now in widespread use in the United States and elsewhere around the world.

Delfi and our products are certified by international regulatory bodies, to independent, third-party standards to guarantee the quality of our products and ensure we meet our customers’ high requirements.  See certificates under Resoures for our Surgical and EMT, and Personalized BFR products.
