The invention relates to an orthotic or prosthetic joint device with an upper part and a lower part arranged in a hinged manner and fastening means for securing the joint device on a user, with at least one hydraulics unit between the upper part and the lower part, which hydraulics unit has a piston that is movable in a housing with an extension chamber and a flexion chamber and that is coupled to the upper part or the lower part, and which hydraulics unit is assigned a pressure supply device with a pump and a pressure accumulator via which the piston, controlled by a control device, is subjected to a pressure, wherein the pump can be operated in generator mode, the pressure accumulator can be coupled drivingly to the pump, and the hydraulic fluid can be conveyed by the pressure accumulator through the pump to the hydraulics unit.

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.

A prosthetic foot comprises an attachment member and two or more flexible members. The attachment member can include a connector configured to connect the attachment member to a user or another prosthetic device. The two or more flexible members can be rotatably attached to the attachment member by rotatable joints such that the flexible members can both rotate and flex relative to the attachment member when the prosthetic foot contacts the ground.

A lower-leg exoskeleton that includes an actuator configured to be worn about a portion a leg of a user that is below the knee of the user; and a foot structure coupled to a first actuator end of the actuator, the foot structure configured to surround a portion of the foot of the user. The foot structure includes one or more sidewalls configured to extend around the foot of the user and including one or more sidewall attachment points for connecting to a base portion, and a base portion configured to reside at a base of the foot of the user and including one or more base attachment points coupling with the one or more sidewall attachment points.

Described here are prosthetic systems, devices, and methods of use therefor. Generally, a prosthesis may be configured to set a resistance to rotation of a prosthetic joint based on a phase of gait. The prosthesis may include a first cylinder, a first piston slidable within the first cylinder, a fluid sump, and a fluid circuit. The fluid circuit may include a plurality of interconnected fluid channels having a unidirectional variable-resistance valve and a set of check valves that are configured to provide unidirectional flow through the valve during piston compression and extension.

A hinged connecting device comprising a damping mechanism intended to counter a predetermined resistance at least during bending of the prosthesis (1), by replacing the muscle groups usually used for this purpose. The damping mechanism (200) is capable of being switched between a first operating mode (M1), selected by default, in which the value of the resistance corresponds to a first maximum value (Vmax), and a second operating mode (M2), that can be actuated only in a hyperextension position (P0) of the prosthesis (1), in which the resistance value corresponds to a second minimum value (Vmin); and the hinged connecting device (2) moreover comprises a fully mechanical locking system (3), arranged in order to allow the second operating mode (M2) to be activated only when the inclination of the tibial part (102) exceeds a first predetermined oriented angle (X1) relative to the vertical.

An orthopedic joint device having a lower leg part, a foot part that is arranged on the lower leg part about a swivel axis such that it can be swivelled, at least a first energy store, and a coupling element. The coupling element can be brought into a coupling position, in which a swivelling of the foot part relative to the lower leg part about the swivel axis in a plantar flexion direction leads to an increase in the amount of energy stored in the first energy store, and a de-coupling position. The orthopedic joint device also has at least one release element, which can be brought into a release position and a locked position. The energy stored in the first energy store can be released by bringing the release element into the release position.
