A flexible inner socket is fabricated by forming a pre-socket. The pre-socket includes a body formed with an opening and an enclosed end. The enclosed end is opposite to the opening. The body of the pre-socket has an outer circumference that is smaller than the inner circumference of the rigid prosthetic socket. Different portions of the body may have different thicknesses. The preform socket is heated. After the heating, the flexible inner socket is formed by molding the pre-socket onto the inner surface of the rigid prosthetic socket to form the flexible inner socket. The inner circumference of the rigid prosthetic socket is reduced by a thickness of the flexible inner socket when the flexible inner socket is attached to the inner surface of the rigid prosthetic socket. An opening of the flexible inner socket may be trimmed after the formation to fit contours of an opening of the rigid prosthetic socket.

In one example of the present disclosure, a system may be configured with a prosthetic liner configured to be worn over a residual limb of a user where the prosthetic liner comprises a first one or more programmed magnets. The system may be further configured with a prosthesis comprising a prosthetic socket configured to receive the residual limb and the prosthetic liner where the prosthetic socket comprises a second one or more programmed magnets. The first one or more programmed magnets are magnetically attracted to and repelled by corresponding ones of the second one or more programmed magnets when the prosthetic liner is received within the prosthetic socket.

Aspects herein are directed to a tubular knit sleeve for a below-the-knee amputee where the tubular knit sleeve includes zoned grip features, zoned cushioning features, zoned traction features, and zoned breathability/permeability features that facilitate the wearer participating in athletic activities, such as wrestling, without a prosthetic leg.

A prosthesis system with a liner and a prosthesis socket, wherein the liner includes a closed distal end, an open proximal end, a lateral surface, which extends from the distal end to the proximal end, and a first connection device. The prosthesis socket includes a second connection device, which is configured to interact with the first connection device. The first connection device is arranged on the lateral surface, and the first connection device and the second connection device are configured to establish a mechanical locking and an electrical contact between the liner and the prosthesis socket.

A prosthetic liner includes a textile cover having at least first and second regions having different elongation from one another. The first region is in a prestretched configuration in at least one orientation relative to an axis of the prosthetic liner and locked in the prestretched configuration according to a layer of elastomeric material located along a surface of the textile cover.

A sheath made of an elastomer material for a prosthesis liner comprises an inner wall and an outer wall defining a sheath body that extends between a proximal end suitable for placing the sheath body onto a stump and a distal end. The sheath is provided at the distal end thereof with a conformable cavity that is formed in the sheath body and is open to the outside via an opening.

A prosthetic socket cooling system and method includes a thermally conductive heat spreader including a curved shaped portion configured to maximize contact with a residual limb of a user. A heat extraction subsystem is coupled through a wall of the prosthetic socket and to the thermally conductive heat spreader and is configured to maintain a desired temperature inside the prosthetic socket.

A conductive human interface includes an insulating body of elastomeric material and a compliant electrode embedded in the insulating body. The electrode is formed from an electrically conductive gel including a polymeric material and conductive particles dispersed in the polymeric material. The conductive particles can be included in the gel in an amount that is not more than about 10% by weight.

A liner is arranged for use in prosthetic and orthopedic devices. The liner defines first and second end portions, and inner and outer surfaces. The liner includes an inner layer having a frictional component and forms at least part of the periphery of the inner liner surface. The inner layer defines a plurality of apertures. A porous element is in communication with the inner liner surface and is connected to the inner layer such that the apertures permit a transfer of air from the inner surface to the porous element. A base layer adjoins the porous element and extends between the first and second end portions of the liner.

The present disclosure includes prosthetic devices, including implants for joints and external prosthetics. The 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.
