A lower limb prosthesis comprises an attachment section (10), a shin section (12), a foot section (14), a knee joint (16) pivotally connecting the attachment section (10) and the shin section (12), and an ankle joint (22) pivotally connecting the shin section (12) and the foot section (14). The knee joint includes a dynamically adjustable knee flexion control device (18) for damping knee flexion. The prosthesis further comprises a plurality of sensors (52, 53, 54, 85, 87) each arranged to generate sensor signals indicative of at least one respective kinetic or kinematic parameter of locomotion or of walking environment, and an electronic control system (100) coupled to the sensors (52, 53, 54, 85, 87) and to the knee flexion control device (18) in order dynamically and automatically to modify the flexion control setting of the knee joint (16) in response to signals from the sensors. When the inclination sensor signals indicate descent of a downward incline, the damping resistance of the knee flexion control device (18) is set to a first level during a major part of the stance phase of the gait cycle and to a second, lower level during a major part of the swing phase of the gait cycle. During an interval including a latter part of the stance phase, the knee flexion control device (18) is adjusted so that the damping resistance to knee flexion is between the first and second levels.

A prosthetic device and related methods includes an elongate support member having a first surface, and an adapter mounted to the support member. The adapter includes a base portion, a movable member, a connector portion, and an adjustment member. The adjustment member is operable to move the movable member relative to the base portion to change an effective length of an interface between the adapter and the first surface of the support member. The connector portion extends from the base portion and is configured to releasably secure the prosthetic foot to a prosthesis.

A prosthesis socket retaining device and a system for securing a prosthesis socket to an upper extremity, comprising a securing part that can be guided along the torso below the axilla of the contralateral, unprovided side of a patient, and a coupling element which can be secured to the prosthesis socket and connected to the securing part, wherein the coupling element is displaceably mounted on the securing part.

A device and method for measuring prosthetic or orthotic slip is presented. An optical sensor device is attached to the prosthesis or orthosis and measures the amount of relative motion between the prosthetic socket and the residual limb surface or between the orthosis and the affected body part. The sensor device is comprised of an optical sensor, a light source, a processing unit and a power source contained within a housing. A system for measuring multidirectional prosthetic or orthotic slip using the sensor device and automatically adjusting the fit of the prosthetic based on a determined threshold is also presented.

A hybrid artificial limb device is provided. A hybrid artificial limb device according to an exemplary embodiment of the present invention comprises: a joint upper side connection member positioned at the upper side of a knee; a knee joint member connected to the joint upper side connection member; and a frame coupled to the knee joint member to be able to perform a pivot rotation, and forming a femoral part. When the frame performs a pivot rotation about the knee joint member, the passive power from the passive driving module and the active power from the active driving module may be selectively or simultaneously provided to the knee joint member.

A prosthesis socket having a proximal insertion opening and an inner circumference which at least partially surrounds a limb stump, at least one connection device for a prosthesis component, which is connectable to the prosthesis sockets at least one actuator operable to change the inner circumference of the prosthesis socket, and at least one sensor coupled to a control device, wherein the control device is connected to the actuator and activates or deactivates same, depending on the received sensor signals, and to a method for adjusting the inner circumference.

An adjustable socket system includes first and second shell components and first and second longitudinal supports connected to a base. The socket system is movable between an open configuration to loosen the fit of the socket system, and a closed configuration to secure the fit of the socket system on residual limb received therein. A tightening system includes a tensioning unit having a handle defining a moment arm rotatable about a rotation axis, and a tensioning element operatively coupled to the handle via a movable connection point located and protected between the first shell component and the first support and to the shell components via a control point. Rotation of the handle displaces the movable connection point and the tensioning element relative to the control point to move the socket system to the closed configuration.

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.

Prostheses include a terminal device, a back-lock mechanism, a wrist, a limb-socket, and a harness system. The terminal device can be a five-fingered mechanical hand that provides a releasable adaptive grasp, and has independently flexible fingers. The limb socket can be 3D printed using a molded model of a remnant limb. The harness strap can encircle an unaffected limb and is coupled to the terminal device with a cable so that a user can control the terminal device. The harness system can include a 3D printed harness ring that couples to the cable.
