Embodiments herein relate to socket liners for prosthetic systems and prosthetic systems including the same. In an embodiment, a socket liner for a prosthetic system is included having a polymeric wall member defining an interior volume. The polymeric wall member having an inner surface bordering the interior volume and an outer surface. The polymeric wall member can include an anterior side, a posterior side, a first lateral side and a second lateral side the second lateral side opposite the first lateral side. A plurality of horizontal ridges can be disposed on the inner surface of the polymeric wall member on the first lateral side and the second lateral side. A plurality of vertical channels can be disposed on the inner surface of the polymeric wall member on the anterior side and the posterior side. Other embodiments are also included herein.

The present invention relates to a medical apparatus (100) for use in manufacturing a plaster impression of limb stump, in particular of a lower stump, wherein the apparatus (100) comprises a pressure vessel (1) with a fluid chamber of pressure chamber (DK) for receiving or storing a fluid (F) being under pressure, wherein the pressure vessel (1) is limited against an exterior (Ä), wherein the pressure vessel (1) comprises an insertion opening (9) for the insertion of a limb stump (KS) into the interior (I) of the pressure vessel (1) and a fluid-tight membrane (5) made of two materials, which are arranged to form or limit the fluid chamber or the pressure chamber (DK). In addition, the present invention relates to a system (300) having a medical apparatus (100) and at least one contact surface (111). Furthermore, the present invention relates to a method.

A prosthesis liner provided for fitting over a stump of a limb. The prosthesis liner includes a main body having an inner face directed towards the skin of the stump, and an outer face directed away from the stump. The prosthesis liner also includes a proximal access opening and a side wall, which extends from the access opening as far as a closed distal end portion of the liner. At least one sealing lip is arranged on the outer face of the main body and protrudes radially outwards from the main body.

A liner for a prosthesis, wherein the liner is made of a liner material and comprises a proximal opening for accommodating an amputation stump, a distal end, a longitudinal direction, which extends from the proximal opening to the distal end, and an auxetic material The auxetic material is a two-dimensional-auxetic material, which is arranged in such a way that an extension of the liner in the longitudinal direction leads to an expansion of a diameter of the liner.

Breathable residual-limb system that admits air and allows sweat to evaporate from the surface of the residual limb. In an embodiment, the system comprises a liner sock to be worn on the residual limb, and comprising air-permeable textile forming a substantially cylindrical portion that is closed on a distal end and open on a proximal end and comprising an internal surface and an external surface. The liner sock further comprises a friction-interface material that covers only a portion of the internal surface of the air-permeable textile, such that, when worn on the residual limb, the friction-interface material contacts a surface of the residual limb, and an uncovered portion of the air-permeable textile which the friction-interface material does not cover allows air to pass between an external environment of the liner sock and the surface of the residual limb.

A prosthetic liner for use with a prosthetic assembly that acts as the interface between the residual limb of an amputee and the socket assembly. The prosthetic liner comprises an outer textile with variable stretch characteristics due to the knit construction and stitching and an interior gel layer. The distal region of the liner textile has less stretch than does the intermediate region or proximal region and is stitched together to form a unitary liner. The liner advantageously minimizes a condition referred to as “pistoning” wherein the distal most portion of the residual limb ascends and descends in the lower portion of the socket creating an unhealthy condition for the residual limb.

A prosthetic liner has a ventilated structure communicating with an interior volume to an exterior of the prosthetic liner, thereby permitting a transfer of air and moisture therebetween. The prosthetic liner includes a facing layer defining a periphery of at least part of the interior volume of the liner, and forming a plurality of apertures extending therethrough. A cushion layer is juxtaposed to the facing layer and forms a lattice structure including a plurality of interstices in communication with the apertures of the facing layer.

A prosthetic socket, comprising a base for distal connection means for attaching a prosthesis component to the prosthetic socket and comprising at least one side wall, which extends from the base in the proximal direction and at least partially extends around a stump to be held in the prosthetic socket, and at least one support for fastening the side wall to the base being arranged on the base.

An adjustable seal system, seal component for use in the system, and method are provided for forming a sealing interface between a residual limb and a prosthetic socket. The seal component is selectively placed over the outer surface of a suspension liner including a plurality of seal bands, which the seal component may removably and securely engage.

Systems and methods for creating custom-fit prosthetic devices, orthotic devices, and related medical devices via three-dimensional printing (3D printing) or additive manufacturing techniques are described. Through the described systems and methods, a residual limb or other body part of a patient is scanned and analyzed to determine measurements and characteristics of the residual limb. The measurements and characteristics of the residual limb are used to design a customized device for the residual limb. The customized device uses multiple different materials. For example, the customized device may use a first material for a frame and a second material for a liner, wherein the first material is more rigid than the second material. The customized device is fabricated using a three-dimensional printer that is capable of printing and bonding multiple different materials at the same time.
