In some embodiments, a body anchor for supporting an assistive device can include: a cuff to exert a compression force on a body part of a user; and one or more tensile elements having first ends and second ends. The first ends of the tensile elements can be configured to be attached to the assistive device. The second ends of the tensile elements can be arranged about the cuff to cause the compression force to vary in proportion to a load exerted by the assistive device.

The present invention relates to a prosthesis covering with a closed cross-section which comprises a first section, a second section and a third section. The second section is arranged in longitudinal direction between the first section and the third section and comprises other material, other diameter and/or other circumference than one or both of the other two sections.

A flexible prosthetic inner socket that resides inside of a rigid prosthetic socket that is fabricated by forming a sized, injection molded, flexible inner pre-socket. The flexible inner pre-socket includes a body formed with an opening and an enclosed end. The Pre-socket can be heated and stretched over a prosthetic residual limb model and then a prosthetic rigid socket can be formed over it. It can also be heated and vacuum-formed inside of an existing hard prosthetic socket in order to provide global volume reduction intended to make the rigid prosthetic socket fit tighter onto the residual limb. The opening of the flexible inner socket may be trimmed after the formation to fit contours of an opening of the rigid prosthetic socket.

Systems and methods for controlling an orthopedic joint device of a lower extremity, the orthopedic joint device comprising an upper part, a lower part mounted in articulated fashion to the upper part, and a conversion device arranged between the upper and lower parts. The conversion device provides for, during pivoting of the upper part relative to the lower part, mechanical work from a relative movement between the upper and lower parts to be converted and stored in at least one energy store and supplied back to the joint device with a time offset in order to assist the relative movement. The stored energy is converted back and the supply of mechanical work takes place in a controlled manner during the assistance of the relative movement.

Systems, devices and methods for detecting ground contact with a lower-limb POD. A sensor array for the POD on a first or second body may include two or more sensors in an array that each detect a distance to a respective target on the other of the first or second body. The first and second bodies may move relative to each other thereby changing an offset distance or distances between the two bodies which is detected by the sensors. In some embodiments, the sensors may include Hall Effect sensors that detect distances to respective magnets. Load data based on the detected distances may be generated for control of the POD, such as for stance phase control.

An orthopedic joint device is provided, the device having an upper part, a lower part pivotably mounted thereon and an actuator fastened to the upper part and the lower part and having a drive shaft coupled to an output element via a force transmission device, the force transmission device having a load transmission element that can by adjusted depending on the load.

A joint for an orthopedic device, the joint comprising: a first element; a spring support mounted to the first element and having at least one spring element; and a second element, the second element being pivotally mounted to the first element in a first swiveling direction counter to a first force applied by the at least one spring element and in an opposite second swiveling direction counter to a second force applied by the at least one spring element.

The invention relates to a method for creating manufacturing data for manufacturing an orthopedic product for a body part of a patient, the method comprising the following steps: providing a digital three-dimensional body part model of the relevant body part for which the orthopedic product is destined to an electronic data processing apparatus, the three-dimensional body part model being based on external body part data acquired from the body part of the patient; identifying at least one rigid body part region in the provided body part model by means of the electronic data processing apparatus, with the remaining region situated outside of the rigid body part region being identified as a yielding body part region on the basis of the identified rigid body part region; creating a reduced three-dimensional body part model by means of the electronic data processing apparatus on the basis of the provided three-dimensional body part model, the identified rigid body part regions and a reduction metric applied in the region of the yielding body part region; and producing manufacturing data for the orthopedic product on the basis of the reduced three-dimensional body part model by means of the electronic data processing apparatus.

Hybrid terrain-adaptive lower-extremity apparatus and methods that perform in a variety of different situations by detecting the terrain that is being traversed, and adapting to the detected terrain. In some embodiments, the ability to control the apparatus for each of these situations builds upon five basic capabilities: (1) determining the activity being performed; (2) dynamically controlling the characteristics of the apparatus based on the activity that is being performed; (3) dynamically driving the apparatus based on the activity that is being performed; (4) determining terrain texture irregularities (e.g., how sticky is the terrain, how slippery is the terrain, is the terrain coarse or smooth, does the terrain have any obstructions, such as rocks) and (5) a mechanical design of the apparatus that can respond to the dynamic control and dynamic drive.
