A prosthetic foot assembly is disclosed. The assembly includes a pivoting ankle joint with a hydraulic system, a prosthetic foot connected to the distal side of the ankle joint, and, at the proximal side, the ankle joint includes a transducer with pyramid adaptor for attaching to a pylon. The ankle joint sensor provides data collection during the stance and optionally, the swing, phases of walking using, for example, strain gages and accelerometers. Also disclosed are methods for real-time feature extraction. Key parameters are captured to which are applied linear, fuzzy logic, neural net, or generic algorithms to determine current state (walking flat, uphill, downhill etc.) in real time and execute changes to the angle between the ankle and foot almost instantaneously based on those parameters.

Prosthetic hydraulic joint with accumulator and methods for controlling joint

A valve includes a case comprising a pin bore, a pin configured to move axially in the pin bore, wherein the pin seals the pin bore, a first channel in communication with the pin bore, a second channel in communication with the pin bore, wherein the second channel comprises a restrictor at a location offset from the first channel, a third channel in communication with the pin bore, wherein the third channel comprises a check valve, and the second channel and third channel are in communication with each other. The valve can be a miniature valve that is used in the control of hydraulic fluid in prosthesis, such as a prosthetic ankle joint.

Hydraulic valve

A prosthesis socket is fitted with a viscoelastic memory material. The material can aspirate a fluid to decrease the interior volume of the socket to compensate for residual limb volume decreases, and fluid can be removed from the viscoelastic memory material to increase the interior volume of the socket to compensate for residual limb volume increases.

Equilibrium socket system

A vacuum pump system for a prosthesis device includes an enhanced suspension mechanism and cooperates with a pressure source, an adaptor assembly, circuitry, and a power source. A virtually air-tight seal between a residual limb and a socket of the prosthesis allows a vacuum fit to be generated by the pump system. The pump system may be controlled with various circuits and processors receiving instructions from a software program. The pump system may be located within a pylon, but yet remain vibrationally and acoustically de-coupled from the pylon.
