biodesigns is pleased to introduce the High-Fidelity™ Interface - a revolutionary new design for both upper and lower limb prosthetic wearers. The High-Fidelity Interface, with patented HiFi technology, offers a radical departure from traditional sockets by providing a high level of intrinsic bone control as the interface captures and reproduces skeletal motion. The results: increased performance, control, stability, range of motion, function, comfort and a much lighter feeling prosthesis. But don't take our word for it. Learn more.
