WillowWood One TF (Transfemoral) System / Willow Wood

Designed for use with the Alpha Duo Liner or the fabricless Alpha SmartTemp Liner!

Reliable suspension for transfemoral amputees has been elusive due to the difficulty of systems maintaining airtight seals. The WillowWood One System provides a consistently secure, comfortable and straightforward solution for transfemoral amputees with no hoses, sleeves, or extra bulk required.

The WillowWood One System was initiated through a grant from the Veterans Administration that covered 26 months of development and testing and included over 40 clinical test patients of various activity levels. The purpose of the grant was to a develop a new socket system for transfemoral amputees that was comfortable, controlled pistoning, reduced sweating, allowed for a comfortable walking gait, and monitored and responded to activity levels of the wearer.

The resulting system meets all these criteria while remaining easy to don and doff and providing unparalleled comfort and security. During clinical testing, amputees repeatedly commented that they could put the system on at the start of their day and no longer needed to adjust their sockets repeatedly throughout their day. The second overwhelmingly reported feedback was that the airtight seal of the system did not break. Amputees could comfortably move (transition from sitting to standing, walk, run, ride a bicycle or motorcycle) with maintained vacuum, and did not experience any movement of the socket.

The WillowWood One System includes an option of a fabricless Alpha SmartTemp Liner or Alpha Duo Liner, the One Gel Sock, the One Seal, and an optional LimbLogic along with the definitive socket and removable brim. As is the norm, diagnostic sockets for this system are created and fit by clinicians. Once the diagnostic socket is fit however, the final, modified diagnostic socket is sent to WillowWood for the fabrication of the removable brim and the definitive socket. This is a no-hassles process as shipping and socket fabrication are part of the WillowWood One System. By teaming the personal clinical service of our customers with WillowWood’s specifically-trained Custom Solutions team, clinicians and their patients can be certain of receiving an air-tight definitive socket.
