A self-aligning prosthetic foot and ankle assembly has an ankle unit pivotally mounting a foot component. The ankle unit contains a hydraulic piston and cylinder assembly having a piston which is linearly movable within a cylinder. The axis of the cylinder is coincident with a shin axis defined by a shin connection interface on the ankle unit. Bypass passages containing damping resistance control valves provide continuous hydraulic damping of dorsi and plantar ankle flexion, the unit being such that, over the major part of the range of damped movement, there is no resilient biasing in either the dorsi or the plantar direction. This confers a number of advantages, including stabilisation of standing, balance control, and improved stair-walking and ramp-walking.

A prosthetic system includes a prosthetic foot with a foot member defining a first end portion, a second end portion, and an intermediate portion defining a curvature and extending between the first and second end portions. A pump mechanism is coupled to the foot member. The pump mechanism includes a housing defining a cavity, and a membrane situated in the cavity. The pump mechanism is movable between an original configuration and an expanded configuration. A movable member includes a first portion coupled to the membrane and a second portion arranged to slidably engage the foot member. Relative movement between the first and second end portions moves the first portion of the movable member relative to the housing and slides the second portion along a length of the foot member to shift the pump mechanism between the original and expanded configurations.

A locking device including a first frame including an insert hole and a first magnetic body, a second frame including an insert recess communicating with the insert hole, and a second magnetic body disposed to face the first magnetic body with a polarity opposite to a polarity of the first magnetic body, and an insert member including a slider inserted into the insert hole and configured to slide relative to the first frame, and a third magnetic body disposed on one side of the slider is provided.

A system and method for transferring proprioceptive and/or sensory information from a prosthesis or from a sensing system disposed at a body part having poor or no sensation, to the skin of a user wearing the prosthesis or the sensing system, includes: a device for providing electrotactile feedback in the form of an electrical stimulation pattern with coding scheme for at least one input signal; and at least one multi-pad electrode configured to be positioned on a part of the body of the user. The multi-pad electrode includes a plurality of pads configured to be selectively and discretely activated/deactivated according to the predefined stimulation pattern.

In the case of known prosthesis systems and socket supplies, the transmission of force is a critical issue. The inventive prosthesis system shall improve known prosthesis systems. According to the invention, a prosthesis system for human limbs is provided, which comprises an implant (101) having at least two joint parts which are movable relative to each other, wherein the first joint part (110) can be connected to a bone part (131, 132) and the second joint part (120) comprises a subcutaneously arrangeable end part (124) on the side being remote from the joint. The invention further relates to a prosthesis system comprising a subcutaneous implant and a socket (170).

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.

The invention relates to a method and a device for generating a vibration pattern in a person, having a drive which sets a mass in rotation, and at least one sensor device which is coupled to a controller which controls the drive as a function of sensor data over the sensor device. The mass (m) is arranged in a homogeneously concentric fashion around its rotational axis (10), and an interface (20) transmits to the person reaction forces from the mass which arise owing to the change in the rotation.

A system for control of a prosthetic device includes at least one Inertial Measurement Unit detecting orientation of a user's foot. The at least one Inertial Measurement Unit is in communication with a device module configured to command at least one actuator of a prosthetic device. The at least one Inertial Measurement unit sends output signals related to orientation of the user's foot to the device module and the device module controls the at least one actuator of the prosthetic device based on the signals from the at least one Inertial Measurement Unit.
