The Vacuum Hip Liner, developed at Velocity Labs, is worn like a pair of shorts which utilizes the compression and tackiness of the liner to hold onto the amputees' skin. A carbon fiber plate is inserted into the vacuum circle in the liner. Vacuum is applied between the liner and the carbon plate, locking the plate and liner together. The plate is then connected to the socket by way of an anterior and posterior lanyard. The only additional suspension is a
contra-lateral belt that control the lateral movement at mid-stance.
