A system and method for method including receiving data representing coordinates of a shape of a body part, forming a model of a flexible inner liner based upon the received data, the flexible inner liner configured to be placed over the body part, receiving, as input, a thickness and an offset of the model of the flexible inner liner, assigning a default density to an internal structure of the model; and varying the default density of the model without changing an outer geometry of the model to create a modified model of the flexible inner liner.

A prosthetic device may include a forearm portion having a prosthesis wall, a prosthesis interior formed by the prosthesis wall, a control module access opening in the prosthesis wall and communicating with the prosthesis interior, an access opening cover reversibly closing the control module access opening and a control module in the prosthesis interior adjacent to the control module access opening. A cosmetic prosthetic glove may be configured for deployment on the forearm portion. The cosmetic prosthetic glove may include a dorsal glove surface and a ventral glove surface. At least one display may be provided in at least one selected position on the cosmetic prosthetic glove. The control module may be configured to be disposed in electronic communication with the display upon deployment of the cosmetic prosthetic glove on the forearm portion. The control module may be operable to present at least one image on the display.

Embodiments of the present invention provide improved prosthetic devices. The prosthetic devices may be fabricated using environmental friendly, renewable and sustainable materials. Methods of manufacturing the devices are also provided. Additionally, the present invention provides an environmental friendly, renewable and sustainable substitute for carbon and/or fiberglass materials.

A liner for an orthopedic or prosthetic device includes a core formed from a porous and compressible material, a first layer secured to the first side of the core and forming a first surface to the liner, and a second layer secured to the second side of the core and forming a second surface to the liner. The first and second layers may comprise different properties from one another and be formed from different materials including fabrics and polymeric materials. A polymeric film may be secured to the core or one of the layers to define at least part of a surface of the liner.

A prosthetic foot device (1) having a longitudinal direction (L) and a transverse direction (T) and comprising a base spring blade (2), an ankle spring blade (3) being made from a composite material comprising glass fibers and a heel spring blade (4), the base spring blade (2) and the ankle spring blade (3) being connected in a forefoot region (5) of the prosthetic foot device (1), the base spring blade (2) and the heel spring blade (4) being connected in a heel region (7) of the prosthetic foot device and the ankle spring blade (3) and the heel spring blade (4) being connected in an ankle region (9) of the prosthetic foot device.

A prosthesis device can include a socket or a kit for forming a socket having a lanyard suspension system. In one example, the lanyard suspension system includes a tightening device having a housing, and tightening the lanyard gathers a tensioning line portion of the lanyard into an interior of the housing.

A medical apparatus is provided for use in manufacturing a plaster impression of limb stump, in particular of a lower stump, wherein the apparatus comprises a pressure vessel with a fluid container of pressure chamber for receiving or storing a fluid being under pressure, wherein the pressure vessel comprises a wall made of a first material, wherein the wall limits the an interior of of the pressure vessel against an exterior, wherein the pressure vessel comprises an insertion opening for the insertion of a limb stump into the interior of the pressure vessel and a fluid-tight membrane made of a second materials, which is arranged to form or limit the fluid container or the pressure chamber. An upper section of the membrane is preferably releasably fastened at or to the pressure vessel by a connector.

A prosthetic foot device having a longitudinal direction and a transverse direction and comprising a base spring blade, an ankle spring blade being made from a composite material comprising glass fibers and a heel spring blade, the base spring blade and the ankle spring blade being connected in a forefoot region of the prosthetic foot device, the base spring blade and the heel spring blade being connected in a heel region of the prosthetic foot device and the ankle spring blade and the heel spring blade being connected in an ankle region of the prosthetic foot device.

Orthotic and prosthetic devices having integrated features such as cushioning features are described, as well as methods for computer aided designing and making of these devices. The orthotic or prosthetic devices comprise a cushioning layer superimposed onto an orthotic or prosthetic shell, the cushioning layer comprising an array (35) of discrete solid and resilient cushioning elements (31). In one preferred embodiment, said cushioning structure is a beam, defined around a centerline of any arbitrary shape. In another preferred embodiment, said cushioning structure has the shape of a spiral.
