Harmony System
Harmony is an active vacuum volume management system for transtibial and transfemoral prostheses. By means of a pump unit, the Harmony system creates a vacuum between liner and socket, making for an unprecedented socket fit.
Along with the greatest level of suspension, Harmony mechanical pumps also provide the functional benefits of rotation and shock absorption to help reduce stress and strain. Effects of the Harmony system include reduced volume fluctuations, improved suspension, reduced forces within the socket, and improved proprioception.
