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.

A sensor assembly for a prosthetic socket may include one or more sensors, such as an electromyography (EMG) sensor, a force sensor, and/or a displacement sensor, for example a magnetic sensor and a magnet. The sensor assembly may be capable of determining if the socket has a proper fit, by using a displacement or force measured or derived from the sensor assembly to determine if there is sufficient pressure between the sensor assembly and the user's skin.

A dynamic support system includes a control system for controlling inflation and deflation of at least one actuator having an inlet connectable to the a control unit of the dynamic support system. The control unit may be in communication with a sensor and may control inflation and deflation of the at least one actuator in response to information provided by the sensor.

A prosthetic ankle includes a pair of prosthetic members movably coupled together to allow movement of the pair of prosthetic members with respect to one another. A hydraulic actuator or damper including hydraulic fluid in a hydraulic chamber is coupled to one of the pair of prosthetic members. A hydraulic piston is movably disposed in the hydraulic chamber and coupled to another of the pair of prosthetic members. A hydraulic flow channel is fluidly coupled between opposite sides of the chamber to allow hydraulic fluid to move between the opposite sides of the chamber as the hydraulic piston moves therein. A voice coil valve is coupled to the hydraulic flow channel to vary resistance to flow of hydraulic fluid through the flow channel, and thus movement of the piston in the chamber, and thus influencing a rate of movement of the pair of prosthetic members with respect to one another.

Knee orthoses or prostheses can be used to automatically, when appropriate, initiate a stand-up sequence based on the position of a person's knee with respect to the person's ankle while the person is in a seated position. When the knee is moved to a position that is forward of the ankle, at least one actuator of the orthosis or prosthesis is actuated to help raise the person from the seated position to a standing position.

Systems and methods for a running controller for a lower limb device including at least a powered knee joint are provided. The method includes collecting real-time sensor information for the lower limb device and configuring the lower limb device to a first state in a finite state model for an activity mode including the running mode. The method further includes, based on the sensor information, transitioning the lower limb device from a current state to a subsequent state in the finite state model for the detected mode when a pre-defined criteria for transitioning to the subsequent state is met, and repeating the transitioning until the activity mode changes. In the system and method, the finite state model includes at least one stance state and at least one swing state, where the at least one stance state includes at least one absorption state and at least one propulsion state.

A prosthetic foot can include an attachment member, at least one first brace, at least one first flexible member, an unpowered actuator, at least one second brace, and at least one second flexible member. The attachment member can include a connector configured to connect the attachment member to a user or another prosthetic device. The at least one first brace can mount to the attachment member and the at least one first flexible member can connect to the attachment member by the at least one first brace such that a force between the ground and the attachment member can be supported by the at least one first flexible member. The unpowered actuator can mount to the attachment member and the at least one second brace can mounted to the actuator. The at least one second flexible member can connect to the attachment member by the at least one second brace such that a force between the ground and the attachment member can be supported by the at least one second flexible member.

Prosthetic devices allow for full articulation of the joint, while absorbing impact of the components during normal use that will reduce wear on the device components and prolong life. The device may include a bone implantable component and a bearing component having an articulation surface that is sized and shaped to substantially mate with at least a portion of the bone implantable component and a damping mechanism that includes a contact member disposed at least primarily inside a cavity; a biasing member biasing the contact member toward an upper aperture of the cavity and means for capturing the contact member within the cavity.

An autonomous wearable leg device employs an array of sensors embedded along a support area, whereby a controller can generate a controlling command and send a controlling command to a prosthetic, orthotic, exoskeletal or wearable component to thereby control the prosthetic, orthotic, exoskeletal or wearable component. A method for controlling autonomous wearable device collects kinetic signals from an array of sensors embedded in a prosthetic, orthotic or exoskeletal component, wherein all values are extracted from at least one feature of the collected kinetic signals, which are applied to a controller that generates a controlling command that is sent to the prosthetic, orthotic exoskeletal component to thereby control the prosthetic, orthotic or exoskeletal component during a portion of a gait cycle.

The invention relates to a method for controlling a prosthetic foot that has a foot part and a lower leg part which are connected to each other by means of a joint that allows a plantar flexion and a dorsal flexion, the damping behavior of the joint being adjustable,

wherein the method comprises the following steps: a) detecting measured values which allow for statements to be made about the rollover behavior of the prosthetic foot by means of at least one sensor, b) comparing the detected measured values and/or at least one parameter determined from said values with stored target values, and c) adjusting the damping behavior depending on the comparison.
