WillowWood One® Transfemoral System

The One Transfemoral System by WillowWood provides a consistently secure, comfortable and straightforward vacuum solution for transfemoral amputees with no hoses, sleeves, or extra bulk required. Patients are able to don the system at the start of the day and take it off at the end, with no extra adjustments needed.

The One System includes a fabricless Alpha SmartTemp or Duo Liner, the One Gel Sock, the One Seal, and a LimbLogic unit, along with the definitive socket and removable brim. The cutaway socket shown on the left shows how the system creates two seal points for secure vacuum suspension.
