A prosthetic liner for use with a prosthetic socket that has a thermoplastic elastomeric (TPE) layer that is in contact with the amputee's residual limb. The TPE layer is not uniform in thickness but has ridges to extend circumferentially around the TPE layer. A fabric layer covers the outer surface of the TPE layer conforming to the ridges and is used as a substrate to form a mechanical bond to an outer seal layer. The outer seal layer is formed by applying an uncured material to the fabric around the ridges thereby creating an air tight boundary layer when inserted into a socket. When vacuum is applied the air is evacuated from the volume below the seal layer.

A prosthetic liner for use with a prosthetic socket that has a thermoplastic elastomeric (TPE) layer that is in contact with the amputee's residual limb. The TPE layer is not uniform in thickness but has ridges to extend circumferentially around the TPE layer. A fabric exterior layer covers the outer surface of the TPE layer conforming to the ridges and is used as a substrate to form a mechanical bond to an elastomeric material. Impregnating the elastomeric material within the fabric exterior occurs by applying an uncured material to the fabric exterior layer and onto at least the apex surfaces located within the sealing regions thereby creating an air tight boundary layer when inserted into a socket. When a vacuum is applied the air is evacuated from the volume below the seal layer.

A prosthesis socket retaining device and a system for securing a prosthesis socket to an upper extremity, comprising a securing part that can be guided along the torso below the axilla of the contralateral, unprovided side of a patient, and a coupling element which can be secured to the prosthesis socket and connected to the securing part, wherein the coupling element is displaceably mounted on the securing part.

The present invention relates to absorbent articles for solving the problem of stopping the excessive accumulations of sweat from building up inside a prosthetic liner. The four layers of materials include: a first layer of a cellulose pulp material having a thickness use for a desired absorbency, a second layer of a wicking cloth material having a thickness use for a desired absorbency, a third layer of a non-toxic double side adhesive tape material one side will stick to both layer, and a fourth layer that is the opposite side which are cover with paper material that can be peeled from the third layer to adhere the inside of a prosthetic liner base sheet to stop the excessive accumulation build-up of sweating.

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 socket system includes a prosthetic lock assembly having a lock body defining a pin hole adapted to receive an attachment pin, and a locking device in the lock body. The locking device is engageable with the attachment pin to unidirectionally lock the attachment pin in the lock body while permitting insertion of the attachment pin in the lock body. A valve assembly is positioned in the lock body that is movable between a closed position and an open position in which the valve assembly is unsealed so that air moves into the lock body via the valve assembly. A release mechanism positioned in the lock body is arranged to both release the locking device from the attachment pin and move the valve assembly to the open position by translating the locking device in the lock body.

The prosthetic device is a general use prosthetic device for shower and daily mobility applications which provides a semi-custom fit. The semi-custom fitment of the leg height and anatomical sizing of the affected leg amputation are possible via configurable liner pads which can be interchanged within the support socket based on need by the wearer. The device is capable of being used on either the left or right leg with no modifications to the device and can be secured to the wearers residual limb via a friction fit between the socket liner and limb. Furthermore, an ergonomic handle and grip provides another point of control for the device to assure safety and security.

A unibody transtibial prosthetic device includes a socket personalized for a specific patient's residual limb. A pylon extends from the socket, the pylon being a unitary polymer structure of interconnected elongated supports having open spaces therebetween. The device also includes a foot-ankle complex, the foot-ankle complex being a unitary polymer extending from the pylon, the foot and ankle unitary structure being shaped to provide multi-axial dynamic flex to enable dorsiflexion, plantar flexion, inversion and eversion motion for smooth symmetric gait performance and energy capture and return. The socket, pylon and foot-ankle complex are portions of a unibody.

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 prosthetic connector system for use with a prosthetic socket having a distal end includes a plate defining a plurality of holes and attachable to the distal end of the prosthetic socket. A component is removably attachable to the plate via the plurality of holes and arranged to connect a prosthesis to the prosthetic socket. The plate defines an outer periphery having an asymmetrical configuration contoured to substantially correspond to at least a portion of the component when the component is attached to the plate via at least some of the holes.
