The WillowWood One TF System provides a secure, comfortable and straightforward elevated vacuum solution for transfemoral amputees with no hoses, sleeves, or extra bulk. During clinical testing, amputees repeatedly shared that they could put the system on at the start of their day and did not have to re-adjust their sockets throughout their day. The second point that clinical test patients shared was that the airtight seal of the system did not break. Amputees could comfortably move around (transition from sitting to standing, walk, run, ride a bicycle or motorcycle, etc.) maintain vacuum, and did not experience any movement of the socket.
